We are looking for a system to test current transmitter sensors only by a short pulse.
Is it possible to use a PicoScope with internal AWG for the following task?
1. Generating a positive pulse with a pulsewidth range of 500..2000us (presettable/preloadable in steps of 5us) triggered via USB command or by external trigger input. The sensor supply line will be switched on by this pulse via an external connected POWER-MOS-FET and then the floating current will be mirrored at a load impedance resistor for masuring the voltage signal...
2. Oscilloscope starts measuring on CH1 (200kS/s..1MS/s = 100..2000 Samples for the above pulsewidth range) when seeing the rising edge of the output pulse (connected to the external trigger input or to another measuring channel)
3. Transferring measuring stream to PC
4. PC-Software do a Mask- or TimestampValue-Test and sets result OK or NOK
Which PicoScope model is in minimum suitable for that?
Kind regards - Jan
