Indeed, but with a 1000:1 probe that becomes a +/- 2000 volt
input range which is sufficient.
That was a work requirement and their solution covers more,
although this would be sufficient for them too.

Peter, didn’t you have some high-voltage
requirements for your application? Looks like the 54003A is
limited to +/- 2 Volts, after whatever reduction the probe
provides. (Just curious. I missed the last couple of days of
discussion.)?

Thank
to those who provided information I was able to successfully
use
54003A input modules as 1 meg probe converter/extenders.
For my company the current COTS device was used to allow
remotely using
scope probes (like the Tek HP probes) at a distance from the
test
equipment, which also happened to have 50 ohm inputs.
However I also
wanted this capability in my home lab and didn't want to
spend a lot of
money.
The 54003A modules are available very inexpensively.? With a
small +/-
10 volt supply and soldering on a 50 ohm coax cable these
modules will
very nicely allow high impedance measurements with 50 ohm
instruments
like spectrum analyzers, up to 300 MHz or so.
These can be had for under $30 shipped from the auction
site.
IMHO a very useful device to have hanging around the lab.
Especially for
the money.
