*
The
HP
8753D
RF source
characteristics in
this mode
are dependent
on the
stability of
the external
LO
source
.
The
RF
source
tracks
the
LO
to
maintain a
stable
IF
signal
at
the
R
channel
receiver
input.
Degradation
in
accuracy is negligible with an HP
8642A/B or HP 8656B RF signal generator as the LO source
.
y
Refer to \HP 8753D Descriptions and Options" for a functional
description.
z
Operation from 3 GHz to 6 GHz requires option 006.
x
Measurement accuracy is dependent on the stability of the input signal.
