Adjustments
LF Compensation
NOTE.
The P5202A probe only has one long-term +LF adjustment and one long-term –LF adjustment. The other three
probe models have two long-term +LF adjustments and two long-term –LF adjustments each.
1.
Verify that the generator output is off.
2.
Connect the probe inputs to the signal output connector on the back of the generator, using adapters if necessary.
Connect the red probe lead to the signal, and the black lead to ground.
3.
Set the probe attenuation to the lower range for the probe that you are adjusting.
4.
Set the oscilloscope horizontal to 4
μ
s/div, Acq mode = Average 16.
5.
Set the generator fast-rise output (rise time waveform) frequency to 10 kHz.
6.
Set the generator fast-rise output voltage to 50 Vp-p.
7.
Enable the generator output. Set the oscilloscope vertical to display the signal.
8.
Make the adjustments in the following order: long-term +LF, long-term +LF*, short-term +LF. (The long-term +LF*
adjustment is not used in the P5202A probe.) Repeat this sequence as necessary to optimize the square-wave response.
WARNING.
Use only an insulated tool to make the adjustment. Failure to do so presents a potential shock hazard.
