8-32. 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 running the SC600 Option in EDGE
mode. If you are, the Control Display shows the following menu.

Perform the following sample procedure to calibrate the pulse response:
1. Connect the Calibrator to Channel 1 on the oscilloscope. Select 50Ω impedance or
use a 50Ω termination directly at the oscilloscope input. Verify that the O key is
lit, 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 (20.0 or
50.0 ns/div).

5. Verify that your oscilloscope exhibits the proper rise time and pulse aberration
characteristics.
6. Remove the input signal by pressing Y.
