Frequency Compensation Adjustment
The N2771A High Voltage Probe has a Frequency Compensation adjustment that compensates for
the input capacitance of the oscilloscope being used with the probe.
Use a square-wave generator set for approximately 100 Hz output. Proceed with the following steps
for frequency compensation.
1
Connect the probe to the oscilloscope.
2
Connect probe tip to square-wave generator.
3
Adjust the square wave generator for approximately 10 volts amplitude.
4
Adjust the oscilloscope time base for 20 usec/div.
5
Use a trimmer tool to adjust the compensation capacitor for the flattest pulse top. See the figure
below for the location of the adjustment.
