Calibrating the Pulse and Frequency Response on an Oscilloscope

4-17
If you have the 5-channel option, the following describes each item in the TRIG menu:
•
TRIG CH
Allows you to select either Channel 5 (C5) or Channel 1 (C1) as the
external trigger channel, with C5 being the default. When you select one channel as
an external trigger, the other channel becomes a source.
•
TIMEDIV
Allows you to select the trigger settings, with ”off” being the default.
When the trigger is on, the instrument does not allow the signal output and trigger
output to be on the same output. If you change the external trigger from C5 to C1 and
select a trigger setting other than “off,” the Calibrator automatically changes the
source from C1 to C2. This change prevents a conflict between the external trigger
and the source.
If you change the external trigger from C1 to C5 and select a trigger setting other
than “off,” the Calibrator automatically changes the source from C5 to C1.

Oscilloscope Pulse Response Calibration Procedure
This sample procedure shows how to check the oscilloscope’s pulse response. Before you
check your oscilloscope, see your oscilloscope’s manual for the recommended calibration
settings.
Before you start this procedure, verify that you are in Edge mode. If you are, the Control
Display shows the following menu:
TDPULSE
off
TRIG

MODE

Perform the following sample procedure to calibrate the pulse response:
1.
Connect the Calibrator to Channel 1 on the oscilloscope. Select 50
Ω
impedance or
use a 50
Ω
termination directly at the oscilloscope input. Verify that OPR appears in
the Output Display, indicating that the signal is connected.
2.
Alter the voltage setting for the signal so it matches the amplitude value
recommended by your oscilloscope manufacturer for calibrating the edge response.
The default setting is 25.00 mV p-p, 1.0000 MHz.
For example, on an HP 54522C oscilloscope, start with a signal of 1 V @ 1 MHz.
3.
Adjust the scale on your oscilloscope to achieve a good picture of the edge.
4.
Adjust the time base on your oscilloscope to the fastest position available
(
≤
1 ns/div).
