Pulse Response Calibration Procedure for an Oscilloscope
This sample procedure shows how to examine the oscilloscope’s pulse response. Before
you examine your oscilloscope, see your oscilloscope’s manual for the recommended
calibration settings.
Before you start this procedure, verify that you are running the oscilloscope option in
Edge mode. If you are, the Control Display shows the subsequent menu.

Do the subsequent sample procedure to calibrate the pulse response.
1. Connect the 5502A to Channel 1 on the oscilloscope. Select 50Ω impedance or use a
50Ω termination directly at the oscilloscope input. Verify that the key is
illuminated, 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 mV @ 1 MHz.
For example, on a Fluke PM3392A 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. For
example, on a Fluke PM3392A oscilloscope with a 1 V @ 1 MHz signal, use
200 mV/div.
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
qualities.
6. Push to remove the input signal.
