Test and Measurement

This is a basic test setup for measuring the output voltages of the inverter circuit. The
output voltage to th e tube can be measured with a dual-channel oscilloscope and two
lo w-capacitance (< 2.5 pf) scope probes. The oscilloscope should be connected
differentially, with the probe grounds connected and floating as depicted in the diagram
Figure 7 indicates how an oscilloscope can be used for achieving these measurement
Channel A should be added to the inverse
waveform on the oscilloscope.
Output waveform
This is what the typical output current waveform should look like as viewed in the above
test arrangement.
