1/100 gain amplifier for 650 V

[Black Pearl]

My requirements are to measure a DUT up to 650 V. I'd like to use standard M-series DAQ for PCI (10 V). As far as I know NI only has some SCC 1/10 amplifier for up to 60 V.

Any recommendations?

We've done some testing of ignition coils, which can get some very high voltages on the primary side. We typically use a voltage divider with a little protection circuitry then run it through a 5B module for isolation.

We are very happy with Dewetron DMM (DAQ-P HV) modules, you can via software set the attenuation and measure up to 1400 V.
