phase locking scheme allows it to operate as a tuned re
-
ceiver by locking all of its local oscillators to its internal
crystal reference oscillator. Set-On Receiver Mode capabil-
ity significantly increases the versatility of the 373XXA VNA
in applications that check for harmonics, intermodulation
products, and signals of known frequency.
Dual Source Control Capability: Dual Source Control
capability allows a user to independently control the fre-
quencies of two sources and the receiver without the need
for an external controller. The frequency ranges and output
powers of the two sources may be specified. A frequency
sweep may be comprised of up to five separate bands,
each with independent source and receiver settings, for
convenient testing of frequency translation devices such as
mixers. Up to five sub-bands may be tested in one sweep.
This feature enables users to easily test mixers, up/down
converters, multipliers, and other frequency conversion de
