Performance Verification Tests
50. Gate Delay Accuracy and Gate Length Accuracy: Agilent E4401B, E4402B, E4404B,
E4405B, and E4407B (Option 1D6)
2-106.
Record the ∆Time (1)-(2) max value as the Maximum Gate Delay in
Table 2-106.
13.Clear all current oscilloscope measurements. Click on Measure, Clear,
and All Measurements.
14.Adjust the oscilloscope horizontal position to center the pulse on
Channel 2 on the display. Switching the trigger source to channel 2
will help with the measurement.
15.Activate the pulse width measurement function for channel 2 of the
oscilloscope.
Click on Measure, Time, and click on +width.
Set the Source to be channel 2 and click OK.
16.Record the +width (2) mean value in Table 2-106 as the 1 µs Gate
Length.
17.On the analyzer, press
