Measuring method of output current
The measuring method of frequency characteristics for output voltage and voltage monitor is as shown
in the figure below. For output current, measure voltage at both ends of the current detection
resistance.
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.
Figure5-3. Measuring method of output current
Representative characteristics are shown on the following pages. However, these do not assure the
performance. Use them as reference data.
Scale of frequency characteristics
Output voltage
Since the gain of the high voltage probe is 1/1000 (-60 dB), 0 dB line on the diagram is actually
60 dB.
Output current
The current detection resistance is 1 k Ω
