Agilent 10400B Series Miniature Passive Oscilloscope Probes
Compensation adjustments
Adjusting high-frequency compensation
To compensate for cable loss in your probe, you’ll need the equipment listed
below.
Equipment Required
1
Remove the probe cover to provide access to the two high-frequency
compensation adjustment resistors.
High-Frequency Adjustments
2
Connect a 50
Ω
feedthrough to the oscilloscope BNC ac cal out.
3
Connect the BNC-to-probe tip adapter to the 50
Ω
feedthrough.
4
Remove any probing aid and the barrel insulator from the probe tip.
5
Connect the probe tip to the BNC-to-probe tip adapter.
6
Connect the probe BNC to the appropriate oscilloscope channel.
7
Press Autoscale, then set the time base to 5 ns/div.
8
Set the sample mode to equivalent time, and the # of averages to 4.
9
Rotate the two high-frequency compensation resistors fully clockwise.
10
Adjust the two high-frequency compensation resistors alternately in
small increments until the displayed waveform has the flattest top.
Do Low-Frequency Compensation First
You must do the low-frequency compensation procedure described previously
before doing this high-frequency compensation procedure.
