USE WITH A 360B
VECTOR NETWORK
ANALYZER
The 680XXB CW generator is compatible with the
WILTRON
Model
360B Vector Network Analyzer (VNA). The following paragraphs pro-
vide instructions for connecting the 680XXB to the 360B VNA so that
it can be used as a signal source for the analyzer operating in the
tracking receiver mode. Operating instructions for the vector network
analyzer can be found in the Model 360B Vector Network Analyzer Op-
eration Manual, P/N 10410-00110.
When operating in tracking receiver mode, the 360B steers its second
local oscillator frequency and phase signal so as to phase-lock itself to
the reference signal from the 680XXB. Due to the inherent resolution
of the 360B’s frequency readout, frequency resolution is limited to
1 kHz intervals.
Connecting
the 680XXB
to the 360B
Connect the 680XXB CW generator to the 360B vec-
tor network analyzer as shown in Figure 7-3.
Step 1
Connect one end of a GPIB cable, 1 meter
in length, to the 680XXB rear panel
IEEE-
488 GPIB
connector. Connect the other
