Sticky Re: What to do when a selftest fails


 

When I enable LO mode I get about -9.7dB from CAL port.

On signal generator mode,

when I set 2.4 GHz, -18.5 dB output (cant?go higher than this)
I measure -26.5? dB

This hints at a blown input switch.
Could you check with your power detector if the output in signal generator mode is also 10 dB low?
E.g. maximum -28 dBm instead of the indicated -18 dBm?
The wiki contains the type number and location of the input switch, it is user replaceable with some expertise in SMD soldering.
