6.
Press Measurebutton on the front panel of the oscilloscope to display
Time@Level measurement.

To Verify Ext Trigger Delay
This test checks the trig delay between the external channel and analog
channels. In the test, the impedance of the 9500B should be set to 50 Ω
and external channel and selected analog channel both set to 50
Ω.
CH-
Ext Trigger Delay Limit: abs(Delay) ≤ 1 ns
Steps:
1.
Connect selected analog channel and external channel of the
oscilloscope to the 9500B with active heads (CH1/CH2) shown as in
2.
Press the ‘Aux’ key at the right of the ‘OSCILLOSCOPE CALIBRATOR’
panel of the 9500B and select the Skew function.
3.
Set impedance of the 9500B to 50Ω, frequency to 1
kHz, and
amplitude to 0.6 V.
4.
Set the oscilloscope Volts/Divto 100mV/div.
