5. Using set the time base to 10 ms/div.
6. Using
toggle the sensitivity of Input A between 5 and 10 mV/div. After
changing the sensitivity wait some seconds until the trace has settled.
Observe the Input A trace, and check to see if it is set to the same position after
changing the sensitivity. The allowed difference is ±0.04 division (= 1 pixel).
7. Using
toggle the sensitivity of Input B between 5 and 10 mV/div. After
changing the sensitivity wait some seconds until the trace has settled.
Observe the Input B trace, and check to see if it is set to the same position after
changing the sensitivity. The allowed difference is ±0.04 division (= 1 pixel).
8. When you are finished, remove the Input A and Input B short.
4.5.2 Input A Trigger Sensitivity Test
Proceed as follows to test the Input A trigger sensitivity:
1. Connect the test tool to the 5500A as shown in Figure 4-3.
ST8004.CGM

2. Select the following test tool setup:
• Press
to select auto ranging (AUTO in top of display).
Do not press
anymore!
• Using
change the sensitivity to select manual sensitivity ranging, and
lock the Input A sensitivity on 200 mV/div.
3. Set the 5500A to source a 5 MHz leveled sine wave of 100 mV peak-to-peak
(SCOPE output, MODE levsin).
4. Adjust the amplitude of the sine wave to 0.5 division on the display.
5. Verify that the signal is well triggered.
If it is not, press
to enable the up/down arrow keys for Trigger Level
adjustment; adjust the trigger level using
and verify that the signal will be
triggered now. The trigger level is indicated by the trigger icon (
).
6. Set the 5500A to source a 25 MHz leveled sine wave of 400 mV peak-to-peak.
7. Adjust the amplitude of the sine wave to 1.5 divisions on the test tool display.
