5.
Set the oscilloscope Sec/Divto 2ns/div.
6.
Set the oscilloscope trigger source to EXT, the trigger slope to Rising,
and the trigger level to 0.
7.
Press Measurebutton on the front panel of the oscilloscope to display
Delay measurement.
8.
Check if the delay is within the limited range above (≤ 1 ns).
9.
Disconnect the test connection.
10.
Check the other analog channel in the same way as steps 1 to 9.

To Verify Trigger Level
This test checks the trigger level accuracy of the ext trigger. In this test,
the impedance of both the 9500B and the oscilloscope should be set to
50
Ω.
CH Trigger Level Error Limit: abs(Error
) ≤
20mV
Steps:
1.
Connect selected channel of the oscilloscope to the 9500B.
2.
Set impedance of the 9500B to 50
MΩ, frequency to
2 kHz, amplitude
to 800 mV, and waveform to sine.
3.
Set the oscilloscope Sec/Div to 50 us/div.
