Hi,
Tektronix made two types of current probes, AC probes and Dc probes.
The AC probes go from some Hz or kHz upto Mhz or GHz. They are robust
and not so expensive. The DC probes are ac probes with an additional
hall sensor in it. The go from DC to say 100MHz. The DC probes are
expensive and the hall sensor is easily damaged by a drop on the
floor. At least, that is my experience. If you want to by a current
probe and need a DC probe, take care that the hall sensor is not
damaged.
regards,
Henk

I assume you've had pieces of kit where you accidentally released
the magic
smoke and they stopped working.
The price of the particular piece of magic in question is high for
at least
two reasons:
1) The spell in question is a mighty powerful one (very difficult and
expensive to make) and cost a lot new ($2200 in 1990)!
2) Simple scarcity

Subject: [time-nuts] Tektronix AM503X current probes
Hello and Happy New Year,
I've always wanted to get a current probe and amp like those just
because of
the magic Mark is talking about. But, specially compared to almost
any other
TM50X plugin, their prices are difficult to justify. Why is it that
they are
so expensive?? ( how much did they cost new ???? ) I've never
bought magic
before :-)...
Regards & 73's
