My HP-3400A RMS Voltmeter (serial 1218A22958) was given a meter movement calibrated in Volts, dBw, and RMS Watts. Most 3400As do not have this meter movement.?

I am fairly certain that I have seen some instrument from HP that had something on the front to indicate a measurement of RMS power. It might have been an audio signal generator or similar. Does anyone know of such an instrument??
I see Minicircuits sell a 6 GHz power meter that they claim measures RMS Power.?
Analog Devices have an article about a 100 MHz to 40 GHz RMS power meter.
