In Band A (100 Hz

GHz),
the
A6A6
First Converter Assembly
functions as the spectrum analyzer input mixer. In Bands B, C, D, and
E (2
GHz
-
22
GHz),
the
A6A8
YIG-Tuned Mixer (YTX) Assembly
functions as both a tracking preselector and an harmonic input mixer.
A preselector is a YIG-tuned bandpass filter that tunes in synchronism
with the tuning of the spectrum analyzer’s 1st LO. This prevents
undesired mixing products from being generated in the harmonic
