5.1 Measuring method
Measuring method of output voltage
Measure the output voltage with the high voltage probe (P6015A by Tektronix). To measure frequency
characteristics, compensate the frequency characteristics of the
high voltage probe using equalizing function of the frequency characteristic analyzer (FRA5095 by
NF Circuit Design Block).
Figure5-1. Compensation of probe
The measuring method of frequency characteristics for output voltage and voltage monitor is as shown
in the figure below.
Connect load as required. Take measurements with the load cable length of approx. 15 cm for
resistance load and with the load cable length of approx. 5 cm for capacity load.
