To Verify Trigger Delay
This test checks the trigger delay of the analog channels. In this test, the
impedance of both the 9500B and the oscilloscope should be set to 50
Ω.
Channel Trigger Delay Limit: abs(T@L) ≤ 1
50 ps
Steps:
1.
Connect the selected channel of the oscilloscope to the 9500B shown
as in
2.
Press the ‘Aux’ key at the right of the ‘OSCILLOSCOPE CALIBRATOR’
panel of the 9500B and select Skew function.
3.
Set the
impedance of the 9500B to 50 Ω, frequency to 1
kHz, and
amplitude to 0.6 V.
4.
Set the oscilloscope Volts/Divto 100mV/div.
5.
Set the oscilloscope Sec/Divto 2ns/div, trigger source is the selected
channel.
