200 kHz and Bandwidth Adjustments

CAUTION

200 kHz and bandwidth adjustments should only be

made by a qualifi ed engineer. Remove the plastic cover to access

these trimmers.
5. Change the square wave output to 200 kHz or to the frequency you

will be using in your testing.
6. Turn the 200 kHz Trimmer for a fl at topped square wave (Figures 2

& 4).
7. Turn the Bandwidth Trimmer for tuning the probe’s bandwidth

(Figure 2).

Figure 3 shows how over- and under-compensated pulse responses

will look.
