How fast can you switch between input ranges?

Post by rvm »

I am considering to buy a Picoscope 4824A, but I am not entirely sure whether this scope is suitable for my application.

I have three coils [A, B and C] that are periodically (at a known time) switching from a 2V signal to a 50mV signal. I would like to measure both signals at the highest possible resolution, so I see two options:
1. I connect each coil to two inputs, one with a 2V input range and one with a 50mV input range. QUESTION: Can the picoscope handle a 2V input signal, while the input is configured with a 50mV input range? Of course this will result in a useless measurement, but will it also break the hardware?
2. I connect each coil to one input and fast switch between the 2V and 50mV input range. QUESTION: can I reconfigure the picoscope from a 2V to 50mV input range within 1millisecond?

Many thanks in advance!

Hi rvm,

I'm not sure if you are still looking for an answer to this, but if you are, then the answer to your question is that (1) would be OK. A ±2V, 500Hz waveform continuously applied to the ±50mV Input Range of the PS4824A would only cause overranging alerts, and is not going to damage the PicoScope over time.

Regards,

Thank you Gerry. My second question is not relevant anymore. So this answers my question.
