Chris, Clemens & All: Just a note on the HP SLM CP1 testing. I had to use a
6dB 75 to 50 ohm attenuator as the HP SLM tracking generator output is 75
ohm, which is why the HP SLM is showing -36 dBm @ 475kHz instead of -30 dBm.

Hello Clemens,
Tuesday, July 21, 2015
>>There are some that go down to 200kHz but these are for the
'high sensitivity' 4410 range (just looks like a 43) which
implies they might need a bit of power ...... borne out by
the power range going to 10kW :)
Indeed there is one element from 0.2-0.535 MHz (power range from 10W to
10kW full scale)
but only for the 4410 Model.One element covers 7 power ranges.
The elements fo the Bird 4410 Model are not compatible with the 43
Model,however.
The 4410 Wattmeter is quite rare to find and much more expensive than
the
much more common 43 Model.

Thanks Clemens, and all those who replied. I'm investigating the
LP100A as it seems a very useful piece of kit, generally, as well as
being available for 136kHz. Much appreciated.
