3.2.2 MCPA Power ON/OFF Sequence Summary
Figure 4 is a functional diagram of the MCPA Power ON/OFF sequence.
Initially, the MCPA +27 VDC and +15 VDC bias are both off.
After depressing the On/Off switch, both the ex27 VDC and +15 VDC bias are
on. Typical current without any RF applied to the MCPA is 18 amps.
Depressing the On/Off switch again will turn off the MCPA module completely, as it was
initially.
