3.7 Output Main Menu
If you press the Output button on the control panel
overlay, or the Output button on the HOME screen,
it will take you to the screen shown in Figure 3-20.
The Output Menu structure is shown in Figure 3-46
on page 3-38.
Figure 3-20 Output System Screen
This screen is broken into 3 main areas:
•
RF Output System - This panel gives the total system Forward and
Reflected power, measured after the filter. It also has a status indication
which will say OK or Fault.
•
Power Amplifier Cabinet - This panel has a button for each PA Cabinet.
For a 1 cabinet transmitter the second cabinet button will be grayed out.
Notice that each button gives a status indication of OK or Fault along
with cabinet Forward and Reflected power (before the filter).
•
Output Control - The control area at the bottom of the screen is used to
control an external rf switch so that the transmitter can be switched from
Antenna to the Test Load. It also reads out the position of the rf switch
based on micro-switches located on the switch. Lastly, it shows the
condition of the Test Load interlock.
NOTE:
If the load interlock is open and the transmitter is switched to the "Test Load"
position, the transmitter output will be muted. If a test load interlock is not
used the appropriate connection on the External I/O board must be jumpered.
For more information see "2.9 External Interlock Connections" on page 2-11.
