Model 5344S
Operation and Programming
This procedure will demonstrate Frequency Offset Locking. The actual front panel output frequency will
be 10 MHz. The rear panel AUX OUT (YTO) will be used for the locking signal.
Connections:
SIGNAL
Example:
The 5344S will operate in CW mode and 10 MHz will be the locked frequency.
NOTE
Since there is no control over the Cavity Oscillator in the plug-in, the
output signal is not phase locked.
1.
First determine the frequency of the Cavity Oscillator in the plug-in. For the 83592A it is 3.8 GHz.
2.
Now enter the Cavity Oscillator frequency into the counter as an offset. Since the 5342A and 5343A
adds all offsets, the value must be entered as negative.
On the counter front panel press:

Select CW mode on the 8350A. If the plug-in has a CW filter, turn it OFF.

Notice that the counter is not displaying 10 MHz, but the frequency of the YTO before being mixed
with the Cavity Oscillator.
7.
Using the 5344A Function keys, press and release MODE until the CW annunciators lights. The FI
key will light indicating the 5344A is waiting for a CW frequency value.
