female “D” connector. The cable wiring and internal signal names are
shown in Table 17. The cable provides 10 RS-422 signals, 10 TTL signals,
three differential analog input A/D signals, and +5V and -5V auxiliary
power from the IFDR. Standard cable length is 1 meter.
B.5 Optional DAFC
The Digital Automatic Freq Control (DAFC) module is used on the
RVP900 for magnetron systems to interface to a digitally controlled
STALO. The DAFC is driven from the Trig-A trigger output SMA of the
IFDR module. DC power needs be provided by running discrete wires, but
