Keysight R8486D/Q8486D microwave transition power sensor question

 

This rf power sensor has a waveguide to TEM transition which then drives the more or less standard diode detector/chopper mechanism (I assume, never seen one).? Does anybody know if there is a filter between the 50MHz ref connector and the transition? Keysight manual says nothing besides not being repairable.? Another question is calibration.? It needs a? 30dB atten so the sensor cals at -30dBm, how does the display know about that?

The D series use the same power sensor cartridges? as the 8487D and can be used to bring those back to life if they have a blown cartridge.? The power meters know which power range they cover by the value of a resistor between ground and a pin on the? ??
power sensor to cable connector.? While they are 'sensitive', you can handle them as long as you use basic anti-static procedures.
There is no filter on the 50Mhz connector, its in direct contact with? the center of the cartridge.

manual says, in part, "Due to the extreme static sensitivity of the power sensors, customer repair is not recommended. If your power sensor should feel or need calibration, return it to Keysight Technologies"
"I'm feeling one here... under anti-static conditions... but, I can't tell if it 'needs' calibration.
Perhaps, it doesn't 'feel' like it?
 

Thanks Richard.?
