Remote control of RF power
Operating this switch locks out the Output set control on the front panel so that
RF power is controlled by a voltage on the remote connector.
Power control divide by ten
This simply reduces the voltage span of the output set control to allow the
setting of powers up to 10% with finer resolution.
Common exciter enable
On units that support this facility this enables a phase-locked-loop that
synchronizes the RF output to a signal on CEX-in
Pulse operation enable
This enables the pulse input facility. If this switch is up then RF can be rapidly
gated by a “TTL” (5v logic) signal on the rear panel pulse input
Display
(a)
The display panel shows the following information:
1. Forward RF power
2. Reflected RF power
3. Set power as a percentage
4. Timer status and progress
5. Matching network tune position
6. Matching network load position
7. Reflected power cutback warning
8. Remote control flag
9. Cooling interlock
10. External interlock
Note that in the event of the RF connector interlock being open this does not
generate a specific warning, however the display will switch to its alternate
“interlock” layout until the connector guard is refitted and the condition reset.
