Testing
This section describes how the MegaPulse Code 360 tester is used to conduct a test. The test can be stopped
immediately at any time by turning OFF the rear-panel power switch.
CAUTION: Make sure you have a load of at least 50Ω connected between Output and Return or use internal
load for testing purposes.
1. Connect the tester to a proper source of supply using the included 18 AWG power supply cord.
2. Plug the Output and Return test leads into the jacks on the front panel.
3. Connect the ends of the test leads to the equipment under test.
4. Turn the Tester on. Toggle the POLARITY switch as needed so that the NOR or REV indicator
is lit.
5. Note that the Voltage meter may indicate that some residual voltage is present on the main storage
capacitor, even when the tester is first turned ON. This is due to inherent charging of the internal
capacitors. Pressing the
TRIGGER switch will discharge the capacitors (be sure not to touch the
output and return leads when pressing the trigger switch).
6.
If no load is connected at the Output, turn ON the 50Ω load switch.
7. Push the yellow CHARGE button. Verify the red TRIGGER indicator is now lit.
8. Adjust the digital VOLTAGE knob up to the desired level. Push the red TRIGGER button, when
the desired voltage is displayed on the front panel meter.
9. Note that the peak amplitude of the measured output waveform is proportional to the voltage that
is read off the front panel of the MegaPulse, but it will always be somewhat lower. This is because
the meter on the MegaPulse is measuring the voltage on the main impulse storage capacitor. This
voltage will intentionally dissipate to some extent before reaching the output leads.
