Measurement/Storage Modules

Measurement/Storage Modules
The Agilent 54657A 54658A and 54659B Measurement/Storage
Modules provide additional measurement and storage capabilities to
the Agilent 54600–Series oscilloscopes. The 54657A has a GPIB
interface and the 54658A has a RS-232 interface. The 54659B has a
RS-232 interface plus an additional parallel output connector which
allows the module to be connected to both an RS-232 controller and a
parallel printer at the same time. The main features are:
•Full Programmability.
•Hardcopy output.
•Three additional automatic voltage measurements (amplitude
preshoot and overshoot).
•Two additional automatic time measurements (delay and phase
angle). User defined measurement thresholds of 10%/90%
20%/80% or selected voltage levels.
•Two additional cursor measurements (voltage in percent and time
in degrees).
•Two additional cursor measurement sources (math function 1
and 2).
•Waveform math functions (addition subtraction multiplication
differentiation integration and FFT)
•Time and date tagging of hard copy and and nonvolatile memories.
Three uncompressed nonvolatile trace memories.
•Additional 64K of nonvolatile trace memory (with data
compression) for up to 97 more trace memories..
•Unattended waveform monitoring by use of mask templates.
•Built-in automatic mask generation and mask editing capabilities.

Installation
This chapter provides you with the information necessary to install
the Measurement/Storage Module on the oscilloscope. Information
required to connect and configure the module to the desired external
devices (such as printer, plotter, computer prior to local or remote
operation is given in the Interface Modules for Agilent 54600-Series
Instruments I/O Function Guide shipped with your module.
Oscilloscope Compatibility
54657A and 54658A These modules are compatible with all Agilent
54600-series oscilloscopes except 54600A, 54601A, and 54602A
oscilloscopes with an operating system version lower than 2.2. If your
54600A, 54601A, or 54602A oscilloscope has an earlier operating system,
it can be updated using upgrade kit HP part number 54601-68702. The
version is briefly displayed on screen when the Print/Utility key
is pressed.
54659B The 54659B in NOT compatible with the 54600A, 54601A,
54602A, or 54610A Oscilloscope. This module is compatible with all
other Agilent 54600-series oscilloscopes with an operating system
version 1.2 or higher or with an operating system version number in the
form of A.XX.XX. If your 54600B, 54601B, 54602B, or 54603B
Oscilloscope has an earlier operating system, it can be updated using
upgrade kit Agilent part number 54601-68704. If your 54610B
Oscilloscope has an earlier operating system, it can be updated using
upgrade kit Agilent part number 54610-68704. The version number is
briefly displayed on screen when the Print/Utility key is pressed.

Operating the
Measurement/Storage Module

Operating the Measurement/Storage
Module
This chapter provides you with the information necessary to use the
additional, or enhanced features that the Measurement/Storage
Module provides. Basic operation for the oscilloscope is covered in
the User and Service Guide for your oscilloscope.
This chapter provides you with practical exercises and detailed
information designed to guide you through operation of the following
functions:
•Math Functions
•utomatic Measurements
•Cursor Measurements
•Mask generation and waveform monitoring
•Trace Storage
2–2

Math Functions
Without the Measurement/Storage module installed, addition and subtraction
are the only math operations provided. In addition to the limited selections,
the single function is performed on the pixel position of the data on the
screen.
With the Measurement/Storage module installed, two functions define up to
six operations that create mathematically altered waveforms (not pixel math.)
•Function 1 will add (+), subtract (–), or multiply (*) the signals acquired
on vertical inputs 1 and 2, then it will display the result as F1.
•Function 2 will integrate, differentiate, or perform an FFT on the signal
acquired on input 1, input 2, or the result in F1; then it will display the
result in F2.
The vertical range and offset of each function can be adjusted for ease of
viewing and measurement considerations. Each function can be displayed,
measured (with cursors), stored in trace memory, or output over the
interface.
Operating the Measurement/Storage Module
Math Functions

Function 1
1Press ± .
2Toggle the Function 1 On Off softkey to enable math function number 1.
3Press the Function 1 Menu softkey
softkey menu with four softkey choices appears. Three of them are related
to the math functions.
4Toggle the + – * softkey until the desired operation is selected.
esults (F1) are displayed on the screen.
ll operations are calculated on a point-by-point basis.
•plus (+) algebraically sum input 1 and input 2 (input 1 + input 2).
•minus (–) algebraically subtract input 2 from input 1 (input 1 – input 2).
•multiply (*) algebraically multiply input 1 with input 2 (input 1 * input 2).
5Press the Units/div softkey and rotate the knob closest to the
Cursors key to set the vertical sensitivity of the resulting
waveform.
6Press the Offset softkey and rotate the knob closest to the
Cursors key to set the offset (from the center graticule) of the
resulting waveform.
Function waveform (F1) is available for viewing, measurement, or storage.
7Press the Previous Menu softkey.
Function 1 Operating Hints
If channel 1 or 2 are clipped (not fully displayed on screen,) the resulting
displayed function will also be clipped. Once the function is displayed, channel
1 and 2 may be turned off for better viewing.
When multiply is the operation selected, the value displayed for units per
division and offset is (V2).
Offset is the value (in V or V2) assigned to the center graticule for function 1.
Normal screen position is 0 V offset, or at the center graticule (until changed).
See "Making Cursor Measurements", and "Saving and Recalling Traces" in this
chapter for more information.
