    Test Set and RF Switching Path Test If you suspect an RF signal path problem with the test set and have verified that the problem in not the front panel RF interface cables, the following procedure will check all of the RF signal paths through the test set. Path checks 1 thru 4 are from the front panel Test Port to the analyzer source and receiver interconnect ports.
