I wish to use my F6.7K as an instrument to measure isolation in a home brew antenna switch.

It is VERY accurate at its resolution. Calibration is done at the factory. I've confirmed my signal strength scale with a NIST calibrated source.

There is a bug in the vertical scalling of the panadapter that could make results inconsistant.
A more accurate reading can be had by turing the RX slice to the signal of interest and then mouse over the s-meter to get a signal level in dbm. If you doing a wide band comaprison, then you may wish to get into the 'WIDE' ( no band pass filter ) mode.
