3.3 Probe Examination
3.3.1 Safety
When using the probe, keep your fingers behind the guard on the probe body to avoid electric shock. Do not touch
metallic portions ofthe probe head while it is connectedto a voltage source. Connectthe probe to the oscilloscope
and connect the ground terminal to ground before youstart any measurements.
3.3.2 Use of Probe Check Wizard
Every time you connecta probe to an input channel, you shoulduse theprobe check wizard to verify that this probe
is operating correctly. There are two ways to do this:
1) Use the vertical menu (for example, push the CH1 MENU button) to set the Probe option attenuation factor.
2) Press the PROBE CHECKbutton to use the Probe Check Wizard and configure the probe option attenuation
factor properlyfollowing menu prompts.
13
3.4 Manual Probe Compensation
Upon thefirst connection ofa probe and an input channel, you should manually perform this adjustmentto match the
probe to the input channel.Uncompensated or miscompensated probes may leadto errors or faults in measurement.
To adjust the probe compensation,follow the stepsbelow.
1. Set the Probe option attenuation in the channel menu to 10X. Set the switch on the probe to 10X and connect
the probe to Channel 1 on the oscilloscope. If youuse the probe hook-tip, ensure it is firmly inserted onto the
probe. Attachthe probe tip to the PROBE COMP ~5V@1KHz connector and the reference lead to the PROBE
COMP Ground connector. Display the channeland then press the AUTOSET button.
2. Check the shape of the displayed waveform.
3. If necessary,use a nonmetallic screwdriver to adjust the variable capacity of your probe until the shape of the
waveformturns tobe the same as the above figure. Repeat this step as necessary. See the figure below for the
way of adjustment.
3.5 Probe Attenuation Setting
Probes are of various attenuation factors which affect the vertical scale ofthe signal. TheProbe Check function is
used to verify if the Probe attenuation option matchesthe attenuation ofthe probe.
As an alternative method toProbe Check, you canpush a vertical menu button (such as the CH 1 MENU button) and
select the Probe option that matches the attenuation factor of your probe.
Make sure that the Attenuation switch on the probe matches the Probe option in the oscilloscope. Switch settingsare
1X and 10X.
When the Attenuation switch is setto 1X, theprobe limits the bandwidth of the oscilloscope to 6MHz. To use the full
bandwidth of the oscilloscope, be sure to set the switch to 10X.

4Main Feature Description
This chapter provides some general information that you need to learn before using an oscilloscope. It contains:
1. Oscilloscope setup
2. Trigger
3. Data acquisition
4. Waveform scaling and positioning
5. Waveform measurement
4.1 Oscilloscope Setup
While operating the oscilloscope, you may often use three features: Autoset, saving a setup and recalling a setup.
Hereinafter they are introduced one by one.
Autoset: This function can be used to adjustthe horizontal and verticalscales of the oscilloscope automaticallyand
set the trigger coupling,type, position, slope, leveland mode, etc.,to acquire a stable waveformdisplay.
Saving a Setup: By default, theoscilloscope will save the setup each timebefore being closed, and automatically
recall the setup once being turned on. (Note: If you modify the setup, please wait for more than 5 seconds
before turning off the oscilloscope to ensure the proper storage of new settings.) You can save 10 settings
permanently in the oscilloscope and reset them as necessary.
Recalling a Setup: The oscilloscope can recall any of your saved setups and the default factory setup.
Default Setup: The oscilloscope is preset for normaloperations when it is shipped from the factory. This is the
default setup.You may recall this setup atany time for your requirements. To view the default settings, refer to
Section 5.6.3.
4.2 Trigger
The trigger determines when the oscilloscope begins to acquire data and displaya waveform. Once a trigger is
properlyset up, the oscilloscope can convertunstable displays orblank screensto meaningful waveforms. Here
introduce some basic concepts about trigger.
Trigger Source
The trigger can be generated with multiple sources. The most common one is the input channel (alternative between
CH1 and CH2). Whether the input signal is displayed or not, it can trigger normal operations. Also the trigger source
can be any signal connected to an external trigger channel or the AC power line (only for Edge triggers). The source
with the AC power line shows the frequency relationship between the signaland the AC commercialpower.
Trigger Type:
The oscilloscope has six types of triggers: Edge, Video, Pulse Width,Slope, Overtime and Swap.
Edge Trigger uses theanalog ordigital test circuitsfor triggering. It happens when the input trigger source
crossesa specified levelin a specified direction.
Video Trigger performs a field or line triggerthrough standard video signals.
17
Pulse Width Trigger can trigger normal or abnormalpulses that meet trigger conditions.
Slope Trigger uses the rise and fall timeson the edge of signal for triggering.
Overtime Trigger happens after theedge of signal reachesthe set time.
Swap Trigger, as a feature of analog oscilloscopes,gives stable displays ofsignals at two different
frequencies. Mainly it uses a specific frequency to switch between twoanalog channels CH1 and CH2so
that the channels will generate swap trigger signals through the trigger circuitry.
Trigger Mode
You can select the Auto or Normal mode to define how the oscilloscope acquiresdata when it does not detecta
trigger condition. Auto Mode performs the acquisition freely in absence of valid trigger. It allows the generation of
untriggered waveformswith thetime base set to80ms/div or slower. Normal Mode updatesthe displayed
waveforms onlywhen the oscilloscope detects a valid trigger condition. Beforethis update, the oscilloscope still
displaysthe old waveforms.This mode shall be used when you wantto only view the effectivelytriggered
waveforms. In this mode, the oscilloscope displays waveforms only afterthe first trigger. To perform a single
sequence acquisition, push the SINGLE SEQ button.
Trigger Coupling
Trigger Coupling determines which part of the signal will be delivered to the trigger circuit. This can help to obtain a
stable displayof the waveform. To use trigger coupling, push the TRIG MENU button, select an Edge or Pulse
trigger, and then select a Coupling option.
Trigger Position
The horizontalposition control establishesthe timebetween the trigger position and the screen center.
Slope and Level
The Slopeand Level controlshelp to define the trigger.The Slope option determines whether the trigger point is on
the rising or falling edge of a signal. To perform the trigger slope control, press the TRIG MENU button, select an
Edge trigger, and use the Slopebuttonto select rising or falling. The TRIGGER LEVEL knobcontrols the trigger point
is on which position of the edge.
4.3 Data Acquisition
When you acquire an analog signal, the oscilloscope will convert it into a digital one. There are two kinds of
acquisition: Real-time acquisition and Equivalent acquisition. The real-time acquisition hasthree modes: Normal,
Peak Detect, and Average. The acquisitionrate isaffected by the setting of time base.
18
Normal: In thisacquisition mode, theoscilloscope samples the signal inevenly spaced intervals to establish the
waveform. This mode accurately represents signals in most time. However, it does not acquire rapid variations
in the analog signal that may occur between two samples, which can result in aliasing and may cause narrow
pulses to be missed. In such cases, you should use the Peak Detectmode to acquire data.
Peak Detect:In this acquisition mode, the oscilloscope gets the maximum and minimum values of the input
signal over each sample interval and uses these valuesto display the waveform. In this way, the oscilloscope
can acquire and display those narrow pulses that may have otherwise been missed in Normal mode. However,
noise will appear to be higher in this mode.
Average: In this acquisition mode, the oscilloscope acquires several waveforms, averages them, and displays
the resulting waveform. Youcan use this mode to reduce random noise.
Equivalent Acquisition: This kind of acquisition can be utilizedfor periodic signals. In case theacquisition rate
is too low when using the real-time acquisition, the oscilloscope will use afixed rate to acquire data with a
stationary tiny delayafter each acquisition of a frame of data. After repeating this acquisition for N times, the
oscilloscope will arrange the acquired N framesof databy time to makeup a new frame ofdata. Then the
waveform can be recovered. The number of times N is related to the equivalent acquisition rate.
Time Base: The oscilloscope digitizes waveforms byacquiring the valueof an input signal at discrete points.
The time base helps to control how often the values are digitized. Use the SEC/DIV knob toadjust the time base
to a horizontal scale that suits your purpose.
4.4 Waveform Scaling and Positioning
The display of waveforms on the screen can be changed by adjusting their scale and position. Once the scale
changes, the waveform display will increase ordecrease in size. Once the position changes, the waveform will move
up, down, right, or left.
The channel referenceindicator (located on the left of the graticule) identifies each waveform on the screen. It points
to the ground levelof the waveformrecord.
Vertical Scale and Position:
The vertical position of a waveformcan be changed bymoving it up and downon the screen.To compare data, you
may align a waveform over another. When you push the VOLTS/DIV button to change the vertical scale of a
waveform, the waveformdisplay willcontractor expand verticallyto the ground level.
Horizontal Scale and Position:
You canadjust the HORIZONTAL POSITION control toview waveform data before the trigger, after the trigger, or
some of each. When you change the horizontal position of awaveform, you are actually changing the time between
the trigger position and the screen center.
For example, if you want to find out the cause ofa glitchin your test circuit, you should trigger on the glitch and make
the pretrigger period long enough to capture databefore the glitch. Then you can analyze thepretrigger data and
perhaps find the cause.Youare allowed to change the horizontalscale of all the waveforms byturning the SEC/DIV
knob. For example, you may want to see justone cycle of awaveformto measure the overshoot on itsrisingedge.
19
The oscilloscope showsthe horizontalscale astime perdivision in the scale readout. Since allactive waveforms use
the same time base, the oscilloscope only displays onevalue forall theactive channels.
4.5 Waveform Measurement
The oscilloscope displays graphs of voltage versus time and can help to measure the displayedwaveform. There are
several ways to take measurements,using thegraticule, thecursors orperforming an automatic measurement.
Graticule
This method allows you tomake a quick, visual estimate and take a simple measurement through the graticule
divisions and the scale factor.
For example, youcan takesimple measurements bycounting the major and minor graticule divisions involved and
multiplying bythe scale factor. If you counted 6 major vertical graticule divisions between the minimum and maximum
values of a waveform and knew you had a scale factor of 50mV/division, you could easily calculate your peak-to-
peak voltage as follows:
6 divisions x 50mV/division = 300mV.
Cursor:
This method allows you to take measurements by moving the cursors. Cursors always appear in pairs andthe
displayedreadouts are justtheir measured values. There are two kinds ofcursors: AmplitudeCursor and Time
Cursor. The amplitude cursor appear as a horizontal broken line, measuring the vertical parameters. The time cursor
appear as a vertical broken line, measuring the horizontal parameters.
When using cursors, please make sure to set the Source to the waveform that youwant to measure on the screen.
To use cursors,push the CURSOR button.
Automatic Measurement:
The oscilloscopeperforms all the calculations automatically in this mode. As this measurement uses the waveform
record points, it is more precise than the graticule andcursormeasurements.Automatic measurements showthe
measurement results by readouts which are periodically updated with the new data acquired by the oscilloscope.
