The stock SSB filters' composite bandwidth, which is typically 2.4kHz at
minus 6db down and 3.4kHz at minus 60db, Peter. Other minus 60db receive
bandswidths can be utilised--provided that the test-receiver offset is
adjusted so that there is an appropriate separation between the
fundamental frequency window of the signal under test and the receive
window. - In other words, if the window of the test-receiver is allowed
to significantly overlap the fundamental frequency window of the
transmitter, the IMD measurement will not be accurate.
cheers.
