3.7.1 Output Service
This screen is accessed from the Output screen in Figure 3-12. It is used for 2 purposes:
a. To monitor the PA Module Circulator reject power. Provides a bargraph and a
DAC count of 0 - 1023 (0 meaning no reflected power and 1023 being maxi-
mum). This allows for a relative reading which can be monitored for changes
which could mean increased system VSWR or a bad circulator. There is no
adjustment for this reading.
b. To monitor Combiner Reject Load Power in the CZ1000F. Provides a bargraph
and a DAC count of 0 - 1023 (0 meaning no reflected power and 1023 being max-
imum). It is used to adjust the phase relationship of PA Module #2 to minimize
the power to the module combiner reject load. The combiner reject load is actu-
ally a 40dB 1kW attenuator whose output is sent to the RF Monitor board where
it is detected and then A/D converted for the reading shown below the “PA 1&2”
bargraph. It is a relative reading which will simply be minimized with the phasing
adjustment R7 on the Backplane Interface board. See "3.7.2 Module Phasing Pro-
cedure".
Figure 3-13 Output Service Screen
NOTE:
The GAIN button can be toggled between LOW and HIGH, with high only being
used to increase the detector resolution for finer adjustment of the module phas-
ing. Proper phasing can usually be obtained using only the LOW setting and
monitoring the DAC reading.
