During RF transmitting, Unblank signal will be generated and sent to synchronize
remote devices. Digital Unblank signal is sent from CAM lite to Exciter via DVMR link.
The analog Unblank signal is generated by the Exciter.
Then, the analog Unblank signal is sent to Driver module lite Unblank distributor,
which outputs same Unblank signals and sends to UPM1, UPM2, RF amplifier interface
board and SRFD3.
On the other hand, Unblank and AC Power Sense signal will be sent to the Magnet
Monitor.
1. Unblank signal may aid in executing ADC algorithms for improving accuracy of the
sensed ADC inputs that have spikes due to RF noise coupling.
2. Power Sense indicates whether or not the System Cabinet is powered-up. The
resulting state shall be made available for the SBC (Single Board Computer) in Magnet
Monitor to read. This will allow the determination of the validity of the Unblank signal.
