I have a pulsed power supply that provides 250v pulses with a pulse width of 2 uS and a frequency of 10 Hz. However, I'm unaware of the polarity of these pulses.
In order to detect the polarity of the pulses, I'm planning to place a diode in series with the output of the pulsed power supply (which only has a single output lead). Depending on the polarity of the voltage, the pulse will either pass through the diode or be defected.
The diode is followed by a charging resistor (20 ohms) in series with a 4 nF capacitor. A voltmeter probe makes contact with the other pole of the capacitor, with the opposite voltmeter probe being grounded. The set up may be shown below:
Based on my specs, I'm expecting to receive some sort of a signal/blip on my multimeter (Fluke 87 III True RMS Meter) to provide some evidence of the presence of a pulse.
Please note that I am not looking to measure the pulse width, voltage, or frequency of the pulses. I'm only looking to see if they are present after the diode.
EDIT 1: The question is whether or not this set up will work to detect a measurable signal.
EDIT 2: The diode shown is a 300v diode, the label shown was only auto-generated by the system.
