1.3 Probe

1.3.1 Probe Safety

A guard around the probe body provides a finger barrier for protection from electric
shock.

Picture 1.3-1

Connect the probe to the oscilloscope and connect the ground terminal to ground before
you take any measurements.

Note ● To avoid electric shock when using the probe, keep fingers behind the guard

on the probe body.

● To avoid electric shock whil e using the probe, do not touch metallic po rtions of
the probe head while it is connected to a voltage source. Connect the probe to
the oscilloscope and connect the ground terminal to ground before you take any
measurements.

1.3.2 Probe Attenuation Setting

Probes are available with various attenuation factors which affect the vertical scale of
the signal. The Probe Check function verifies that the Probe attenuation option matches
the attenuation of the probe.

7

Find Quality Products Online at: [e-mail]

www.GlobalTestSupply.com

You can push a vertical menu button (such as the CH 1 MENU button), and select the
Probe option that matches the attenuation factor of your probe.

Note: The default setting fo r the Probe option is 1X.

Be sure that the attenuation switch on the probe matches the Probe option in the
oscilloscope. Switch settings are 1X and 10X.

Note: When the attenuation switch is set to 1X, the probe limits the bandwidth of the
oscilloscope to 6MHz (according to Probe spec). To use the full bandwidth of the
oscilloscope, be sure to set the switch to 10X

1.3.3 Probe Compensation

As an alternative method to Probe Check, you can manually perform this adjustment to
match your probe to the input channel.

Picture1.3-2

1. Set the Probe option attenuation in the channel menu to 10X. Set the switch to 10X
on the probe and connect the probe to channel 1 on the oscilloscope. If you use the
probe hook-tip, ensure a proper connection by firmly inserting the tip onto the probe.

2. Attach the probe tip to the PROBE COMP 3V connector and the reference lead to the
PROBE COMP Ground connector. Display the channel and then push the “AUTO”
button.

2. Displaying the FFT Spectrum

Press the MATH button to display the Math Menu. Use the options to select the Source
channel, Window algorithm, and FFT Zoom factor. You can display only one FFT
spectrum at a time. You can select “Full screen” or “Split” in “Display” option to display
FFT waveform on full screen or display channel waveform and its FFT waveform on half
screen at a time.

Picture2.6-10 FFT function

3. Select FFT window

Windows reduce spectral leakage in the FFT spectrum. The FFT assumes that the YT
waveform repeats forever. With an integral number of cycles, the YT waveform starts
and ends at the me amplitude and there are no discontinuities in the signal shape A
non-integral number of cycles in the YT waveform causes the signal start and end points
to be at different amplitudes. The transitions between the start and end points cause
discontinuities in the signal that introduce high-frequency transients.
According to the tested options and source speciality, make sure the window you
need to use.

2.7.1 Horizontal Control Knob

You can use the horizontal controls to change the horizontal scale and position of
waveforms. The horizontal position readout shows the time represented by the center
of the screen, using the time of the trigger as zero. Changing the horizontal scale causes
the waveform to expand or contract around the screen center.

■ Horizontal “POSITION” Knob

1. Adjust the horizontal position of all channels and math waveforms (the position of the
trigger relative to the center of the screen). The resolution of this control varies with the
time base setting.

2. When you press the horizontal “POSITION” Knob, you can set the horizontal position
to zero.

■“S/div” Knob

The feature is very useful because you can see the events that led up the trigger point
everything to the right of the trigger point is called posttrigger information the amount of
delay range (pre-trigger and posttrigger information) available is dependent on the
sweep speed selected.

2.8.1 Signal Source

You can use the Trigger Source options to select the signal that the oscilloscope uses
as a trigger. The source can be any signal connected to a channel BNC, to the EXT TRIG
BNC or the AC power line (available only with Edge triggers).

2.8.4 Position

The horizontal position control establishes the time between the trigger position and the
screen center. You can adjust the horizontal “POSITION” knob control to view waveform
data before the trigger, after the trigger, or some of each. When you change the
horizontal position of a waveform, you are changing the time between the trigger and the
center of the display actually. (This appears to move the waveform to the right or left on
the display.)

2.8.5 Slope & Level

The Slope and Level controls help to define the trigger. The Slope option (Edge trigger
type only) determines whether the oscilloscope finds the trigger point on the rising or the
falling edge of a signal.

The TRIGGER LEVEL knob controls where on the edge the trigger point occurs.

2.8.6 Trigger Holdoff

You can use the Trigger Holdoff function to produce a stable display of complex
waveforms. Holdoff is time between when the oscilloscope detects one trigger and when
it is ready to detect another. The oscilloscope will not trigger during the holdoff time. For
a pulse train, you can adjust the holdoff time so the oscilloscope triggers only on the first
pulse in the train.

When you acquire a signal, the oscilloscope converts it into a digital form and displays
a waveform. The acquisition mode defines how the signal is digitized and the time base
setting affects the time span and level of detail in the acquisition.

■ Sampling: In this acquisition mode, the oscilloscope samples the signal in evenly
spaced intervals to construct the waveform. This mode accurately represents signals
most of the time.

Advantage: You can use this mode to reduce random noise.
Disadvantage: This mode does not acquire rapid variations in the signal that may occur

between samples. This can result in aliasing may cause narrow pulses to be missed. In
these cases, you should use the Peak Detect mode to acquire data.

Picture 2.9-2 Sampling modes

■ Peak Detect: Peak Detect mode capture the maximum and minimum values of a
signal Finds highest and lowest record points over many acquisitions.
Advantage: In this way, the oscilloscope can acquire and display narrow pulses, which
may have otherwise been missed in Sample mode.

Disadvantage: Noise will appear to be higher in this mode.

Picture 2.9-3 Peak Detect mode

Average: The oscilloscope acquires several waveforms, averages them, and

■

displays the resulting waveform.

Advantage: You can use this mode to reduce random noise.

Picture 2.9-4 Average Mode

■ Equivalent Time Sampling:

The equivalent time sampling mode can achieve up to 20 ps of horizontal resolution
(equivalent to 50GSa/s). This mode is good for observing repetitive waveforms.

■ Real Time Sampling: The scope has the highest Real-time sampling rate
up to 1GSa/s.

■ “RUN/STOP” Button: Press the RUN/STOP button when you want the
oscilloscope to acquire waveforms continuously. Press the button again to stop the
acquisition.

■ “SINGLE” Button: Press the SINGLE button to acquire a single waveform. Each time
you push the SINGLE button, the oscilloscope begins to acquire another waveform.
After the oscilloscope detects a trigger it completes the acquisition and stops.

52

Find Quality Products Online at: [e-mail]

www.GlobalTestSupply.com

When you push the RUN/STOP or SINGLE buttons to start an acquisition, the



oscilloscope goes through the following steps:

1. Acquire enough data to fill the portion of the waveform record to the left of the trigger

point. This is also called the pre-trigger.

2. Continue to acquire data while waiting for the trigger condition to occur.
3. Detect the trigger condition.
4. Continue to acquire data until the waveform record is full.
5. Display the newly-acquired waveform.

■ Time Base: The oscilloscope digitizes waveforms by acquiring the value of an input
signal at discrete points. The time base allows you to control how often the values are
digitized.
Use S/div knob to adjust the time base to a horizontal scale suits your purpose,

■ Time Domain Aliasing

Aliasing occurs when the oscilloscope does not sample the signal fast enough to
construct an accurate waveform record. When this happens, the oscilloscope displays
a waveform with a frequency lower than the actual input waveform, or triggers and
displays an unstable waveform.

displayed. There are scale, Cursor and auto measure modes.

2.11.1 Scale Measurement

This method allows you to make a quick, visual estimate. For example, you might look
at waveform amplitude and determine that it is a little more than 100 mV. You can take
simple measurements by counting the major and minor graticule divisions involved and
multiplying by the scale factor. For example, if you counted five major vertical graticule
divisions between the minimum and maximum values of a waveform and knew you had
a scale factor of 100mV/div, then you could easily calculate your peak-to-peak voltage
as follows:
5 divisions x 100 mV/division = 500 mV.
