oscilloscope to high voltage shv ports?

Hi,

We are building an enclosure for a high voltage pulser with 3 pulsed outputs. The outputs on the three channels are bipolar square waves of +-500V at up to 40kHz. We would like to take some RG59 cable inside the enclosure, and use it to connect the three internal pulser circuit outputs to three shv ports on the enclosure, so that we can monitor the output easily later on.

Our question is how to easily run a cable from the oscilloscope (rated to 300VDC) to the SHV outputs of the enclosure. It obviously needs a voltage reduction (e.g. 10-100x). We know that we could technically put voltage dividers on every single output in the enclosure, but I'm wondering if anyone knows of a more standard cable/option to do this? Isn't there a BNC to SHV cable with a 10x reduction somewhere?

We can't find an easy commercial option and are looking for advice from others who may know what is standard practice.

Thanks,
Brandon

You are asking about high voltage oscilloscope probes respectively inbuilt voltage dividers in your instrument, not "cables".

You should give a rough idea about the intended measurement bandwidth respectively signal rise time. Also the acceptable pulser output load by the measurement circuit. Passive oscilloscope probes, e.g. a 100:1 probe that could be used to monitor the output voltage use BNC connectors but not regular coaxial cable. A coaxial monitor output jack should have 50 ohms impedance which doesn't well fit a passive voltage divider.
