eZ-Analyst is the result of more than ten years of software
development and customer input. This software adds real-
time continuous and transient data acquisition to Wave-
Books, ZonicBook/618E, and to 640, 650, 652, and 655*
dynamic signal analyzers. Analysis can be in the time,
frequency, or order domain.
eZ-Analyst is operated through a series of setup windows
that display only the information deemed important to your
test. Acquisition configuration involves selecting desired
acquisition parameters from user-friendly menus.
*eZ-Analyst can be used for the dynamic channels of the 655 device, but not for the temperature channels. If you will be using a
655 for temperature applications you will need to use other software, such as eZ-TOMAS or DASYLab.
Features
•Real-time FFT analysis
•Easy-to-use graphical user interface provides fast setup
•Large number of display options: Time Waveform, Spectrum, Auto Spectrum,
FRF, Cross, PSD, Transfer Function, Coherence, Octave, and Waterfall
•Order Normalization and Order Tracked Plots
•Multiple Plot Overlays using exported data files
•Export to Excel, ME Scope, SMS Star, or UFF Type 58 ASCII or Binary
•Save/Recall display setups with multiple display windows and overlays
•Wide selection of real-time analysis features, including integration/differentiation
averaging, and much more

2-2 Introduction 896991 eZ-Analyst Series
Four Function View Windows in Playback Mode
eZ-Analyst is a graphical analysis application that can be used to collect, analyze, record, and
play back recorded data. With use of a 640, 650, 652, 655*, ZonicBook/618E, or WaveBook
analyzer, ez-Analyst can collect and display multiple channels of data in real-time. The
graphical displays can consist not only of the raw time-domain data, but also plots of
frequency domain data. For example, real time FFT (Fast Fourier Transform) plots.
Data that is recorded to disk-file is in the raw time domain and can be played back for
additional analysis time and time again. For example, a raw signal can be played back over-
and-over using different FFT Window algorithms to manipulate the signal. Once the desired
results have been achieved, the new data can be exported to a different file and format, while
preserving the original file. In addition, the playback capability does not require the presence
of analyzer hardware.
*eZ-Analyst can be used for the dynamic channels of the 655 device, but not for the temperature channels. If you will
be using a 655 for temperature applications you will need to use other software, such as eZ-TOMAS or DASYLab.

2-4 Introduction 896991 eZ-Analyst Series
Measurement Mode
The Measurement Mode is an active data-collecting mode, which, for that reason, requires the
use of data acquisition hardware. The Measurement Mode can only be selected if analyzer
hardware is present.
The Measurement Mode acquires data using one of the following three methods:
(1) Scope-Continuous, (2) Scope-Single, and (3) Record.
The Scope-Continuous and Scope-Single methods display data, but do not log data. The
scope methods are useful for signal validation and checkout. The Record method, in addition
to displaying data, logs data-to-disk based on user-defined start and stop criteria.
In addition to being selected from the Task Menu, the Measurement Mode can be selected
from the Task Tool Bar by clicking the <Change Task Mode> button while in the Playback
Mode. Clicking this button from Measurement Mode will change the task mode tool bar to
Playback.
The Measurement Mode is detailed in Chapter 3.
Measurement Mode Task Bar
Playback Mode
The Playback Mode does not require the presence of physical hardware. When in Playback,
eZ-Analyst is strictly a post-acquisition display and analysis program. Raw time-domain data,
that has been recorded-to-disk, can be played back for analysis repeatedly. For example, a
raw signal could be played back several times, each time using a different FFT Window
algorithm to manipulate the original signal. Once the desired results have been achieved the
new data can be exported in a new format and to a different file. The original file can remain
unchanged, and kept for future analysis.
To activate the Playback Mode, select Playback/Review on the Task Menu. An option is to click
the <Change Task Mode> button (the first button in the tool bar) while in the Measurement
Mode. If an analyzer (acquisition hardware) is not available eZ-Analyst will automatically
enter the Playback mode and will display the data that was most recently recorded to disk.
The Playback Mode is detailed in Chapter 3.

A Word About Configuration
Configuring Input Channels
eZ-Analyst makes use of various menus and related windows for the purpose of configuration.
Chapter 4 is devoted exclusively to the Edit menu. It is that menu which provides access to
the Configuration Window (see figure). It is from the Configuration Window that the majority
of acquisition related settings are made.

Foreword
The menus, with exception of the Task Menu and the Edit Menu,are presented in the
order that they appear on eZ-Analyst’s main window. The Task Menu is discussed first
since it is from this menu that the user (1) selects Measurement Mode or Playback
Mode and (2) makes use of the Auto-Ranging feature for input channels.
The Edit Menu is perhaps the most significant of all eZ-Analyst menus and is the most
frequently used. Chapter 4 is dedicated solely to the Edit Menu.
Task Menu
Task Menu > Measurement Mode
The Measurement Mode is an active data-collecting mode, which, for that reason, requires the
use of data acquisition hardware. The Measurement Mode can only be selected if an
appropriate data acquisition device is used; otherwise, eZ-Analyst will run in the Playback
Mode.
The Measurement Mode acquires data using one of the following three methods:
(1) Scope-Continuous, (2) Scope-Single, and (3) Record.
The Scope-Continuous and Scope-Single methods display data, but do not log data. The scope
methods are useful for signal validation and checkout. The Record method, in addition to
displaying data, logs data-to-disk based on user-defined start and stop criteria.
In addition to being selected from the Task Menu, the Measurement Mode can be selected from
the Task Tool Bar by clicking the <Change Task Mode> button while in the Playback Mode.
Clicking this button from Measurement Mode will change the task mode tool bar to Playback.

The Task Bar buttons will change accordingly.
Record Starts recording data-to-disk in continuous time. Note that a ZonicBook or
WaveBook must be used to acquire data.
Scope-Continuous Starts a block-time data acquisition. This scope method is typically used to
acquire impact data or to take measurements when data storage is not required.
Scope-Single Starts a single-time run data acquisition. This scope method is typically used to
acquire impact data or to take measurements when data storage is not required.
Signal Generator The Signal Generator button toggles between two images and is only active when
hardware is present.
The sine wave button indicates that the generator is ON. Clicking on it will turn the
generator OFF and the button image will change to a circled red line, indicating that
the generator is OFF.
Clicking the button, while the “Off Status” image is present, will turn the Signal
Generator back ON, and will change the button to show the sine wave image.
Note: For WaveBook applications you must set the applicable output channel
(that is to generate the signal) to “Active.” See, Output Channel Setup in chapter 4.

Cursor Lock An active cursor lock button will have the image of an opened or locked padlock.
When the padlock is locked (closed), cursors in multiple windows will be
synchronized and locked, providing that the windows are of the same time domain,
frequency domain, or have the same octave band data.
An opened padlock image indicates that cursors in multiple windows have
independent cursor movement, i.e., they are unsynchronized.
Export This button exports data, if export conditions are set. For details, see the section,
Export Menu> Export Function Data.
Task Menu > Playback / Review Mode
The Playback Mode does not require the presence of physical hardware. When in Playback, eZ-Analyst is
strictly a post-acquisition display and analysis program. Raw time-domain data, that has been recorded-
to-disk, can be played back for analysis repeatedly. For example, a raw signal could be played back
several times, each time using a different FFT Window algorithm to manipulate the original signal. Once
the desired results have been achieved the new data can be exported in a new format and to a different
file. The original file can remain unchanged, and kept for future analysis.
To activate the Playback Mode, select Playback/Review on the Task Menu. An option is to click the
<Change Task Mode> button (the first button in the tool bar) while in the Measurement Mode. Also,
note that when a WaveBook or ZonicBook is not available, eZ-Analyst will automatically enter the
Playback mode and will display the data that was most recently recorded to disk.
You can temporarily change three aspects of Engineering Units (EU) to customize your
playback of data (see figure at right). These are EU Mode, mV/EU and EU Offset. To
change the settings navigate as follows: Edit Menu>>Configuration>>Input Channels Tab;
and then make the desired changes. The new settings will be applied to your playback
session; however, upon closing eZ-Analyst the settings will default to those originally
configured at the time the data was recorded. Chapter 4 includes additional information
about the Configuration Input Channels tab.

Task Menu > Input Range (Auto/Manual) *
Auto-ranging is a procedure that automatically sets the input full-scale voltage (FSV) range for
input channels. The FSV is set by measuring a representative sample of real-time data. Auto-
ranging is only performed on active channels.
Auto-ranging works best if you supply the maximum expected voltage range for the data that
will be captured during the acquisition. Therefore, make the Auto Range Duration long enough
to apply a typical signal. In addition, make sure that the Auto Range Analysis Frequency is
fast enough to capture the high frequency component. Typically the Analysis Frequency will
be the same setting as eZ-Analyst’s Acquisition Analysis Frequency.
AutoRange Dialog Box, from a WaveBook
Note that AutoRange Dialog Boxes for other analyzers are similar.
* You can access the dialog box by clicking the <Auto Range> button, which is located on the
Input Channels tab, when in the “Measurement Mode.”

3-4 Menus 987990 eZ-Analyst
Mode
The Mode panel consists of three radio buttons, which are used to select one of the following
range modes: AutoRange(%), AutoRange(V), or ManualRange(V).
Starting FSV
The Starting FSV (Full Scale Voltage) panel consists of three radio buttons, which are used to
set the starting FSV to Maximum, Minimum, or Current.
Channel Gauges
The channel gauges, one per channel, display the instantaneous peak value as percentage or
voltage, depending on the mode that was selected. The color of the vertical bar has the
following significance:
Yellow The signal range is from 0 to the minimum Full-Scale Voltage set in the Auto-range Setup
window.
Green The signal range is from the minimum to the maximum of the Full-Scale Voltage set in the
Auto-range Setup window.
Red The signal range is over the maximum of the Full-Scale Voltage set in the Auto-range Setup
window.
%, FSVF, & Factors Display
Maximum FSV is the high-end limit for the input voltage.
Note that 25.7 V is the highest possible FSV for a ZonicBook
Medallion.
Minimum FSV is the low-end limit for the input voltage. In
the figure at the right Minimum FSV is set to 0.2 volts.
HI Accept %defines the highest acceptable percentage of
peak input voltage for the selected FSV, i.e., Current, Minimum, or Maximum. Thus, if
our selected FSV was 0.2 V and we had an upper limit of 90%; then our upper limit in
volts would be 0.18 V. An example follows as to how exceeding this value causes a range
adjustment.
LO Accept %defines the lowest acceptable percentage of peak input voltage for the
selected FSV, i.e., (Current, Minimum, or Maximum). Thus, if our selected FSV was 0.2 V
and we had a lower limit of 10%; then our actual low limit in volts would be .02 V.
Incr Factor (Increasing Factor) is the factor by which the Current FSV will increase,
should the peak exceed the upper limit. In the figure we see that the Increasing factor is
1.5.
Decr Factor (Decreasing Factor) is the factor by which the Current FSV will decrease,
should the peak not reach the lower limit. Keeping the decrease factor at “1” will result in
no decrease of the Current FSV. Setting the Decrease Factor to 0.8 would cause the
Current FSV to decrease to 80% of its value if the peak fell short of the low limit.
Note: These are the same values that were entered in the Vpeak column in the Channel Setup
window. The values are immediately replaced when the Auto ranging process begins.

Maximum FSV set at 25.7 V
Minimum FSV set at 0.2 V
Upper Limit set at 90%
Lower Limit set at 10%
Increasing Factor set at 1.5
Decreasing Factor set at 1
In this example we have set the radio button for
Current FSV instead of Minimum or Maximum
(note 2). The starting value, in the example, is 0.20 V.
In the first iteration we see
that we have a peak of 0.19 V.
This falls outside of our band of
0.02 to 0.18 V that was
established by our upper and
lower limit percentages; i.e.,
90% of the Current FSV and
10% of the FSV.
An Example of Auto-Ranging
As a result, the Current FSV is increased by a factor of 1.5 (our Increasing Factor) and the
Current FSV becomes 0.30 V. Our limits, in volts, also changed since we are now looking
at percentages of 0.30 volts instead of the same percentages of 0.20 volts.
In the second iteration of our example, we see a 0.22 volt peak. This value is within our
established limits so the Current FSV does not change.
Note 1: If the Capture Mode is the Input Channel (Trigger Mode), the Auto Range process waits for a
trigger.
Note 2: A Start FSV of Minimum or Maximum can selected instead of Current FSV, as in our example.
Minimum FSV is the default.
Task Menu > Calibration
When calibration is performed, a signal of known Peak level [or RMS value] is supplied to a
transducer that is connected to an active input channel. An accelerometer calibrator or piston
phone is typically used to generate the calibration signal for vibration sensors and microphones,
respectively.
Examples:
Accelerometer calibrators typically make use of linear engineering
units and, as their name implies, are used for calibrating
accelerometers.
Piston phones are most often used for calibrating microphones. Piston
phones typically make use of decibel (dB) engineering units.
eZ-Analyst includes a Calibration window for selecting the channels to be calibrated and for
entering several signal-related parameters. In addition, the calibration is actually started from
the window.

When you are in “Measurement Mode” you can access the Calibration window from the Task
Menu or from the Input/Output Channels tab.
Calibration Display Screen
When a channel is calibrated, the number of averages used will be 5, or the
number that is designated in the “No. of Averages” field (located on the
Analyzer Tab). The greater of the two values will be used, automatically.
A discussion of the various regions of the Calibration window now follows.
The section concludes with an example.
Calibration Process
Single
Channel Used to select one active channel at a time. When the calibrator only has one channel output, the Single Channel method must be used. When
Single Channel is selected, the “Active” column shows a radio button next
to each channel.
Multiple
Channel Used to select two or more channels for simultaneous calibration. This is only an option when the calibrator offers more than one output. When
Multiple Channel is selected, the “Active” column shows a checkbox next to
each channel.
Calibration Domain
With the use of Fourier Transform, any signal can be viewed from a time domain or a
frequency domain. Either domain can be selected for use in the calibration process.
Time The overall value is computed using time domain data.
Freq-
uency The overall value is computed with frequency domain data by summing up frequency component of FFT spectrum.
Calibrator Frequency (Hz)
This field is used to enter the frequency setting of the calibrator. The analysis frequency,
which is twice this frequency, is used if possible. Otherwise, the maximum allowed
analysis frequency is used.
