Page 12: J1 - Input
ATOM Ku BUC/SSPA Revision A 20W/25W/40W/50W 908239 Section 2.3 J1 – I NPUT The IF input is a 50 ohm type-N connector. The input is to be applied here (950-1700 MHz for Extended Band; 950-1450 MHz for Regular Band). Also, the 10 MHz signal input is diplexed onto this line. Therefore, the IF signal and 10 MHz reference are both traveling on this line. -

ATOM Ku BUC/SSPA Revision A 20W/25W/40W/50W 908239 Pin D is also configurable to be either active high or active low. When configured as active high, any voltage between 3.0 V and 5.0 V (relative to case ground) will mute the output. When configured as active low, any voltage between 0.0 V and 0.8 V (relative to case ground) will mute the output. -

ATOM Ku BUC/SSPA Revision A 20W/25W/40W/50W 908239 ESSAGE EFINITIONS getident This command returns the part number, software revision and serial number of the unit. Figure 2-3: Command getident getstatus This command instructs the unit to respond with fault flag, forward power and temperature. Note: reverse power, “revpwr”, in the response is a future enhancement and is not currently supported. -
Page 17: Figure 2-5: Command Getfaults
ATOM Ku BUC/SSPA Revision A 20W/25W/40W/50W 908239 getfaults This command gets the status of the mute, over temperature and pll loss of lock. For mute, “0” indicates the unit is in an unmuted state. A “1” indicates a muted state. Note that a “1” does not necessarily indicate an error as the unit could have been commanded into a mute state (see “setmute”... -

ATOM Ku BUC/SSPA Revision A 20W/25W/40W/50W 908239 Section 2.6 J3 – DC P OWER Units typically require 20V to 56V DC power. Refer to the specific configuration of the unit for the exact voltage range. Power is supplied through a four pin type cannon connector. Two pins are used to deliver the positive connection and two pins are used for the negative connection in order to reduce resistance. -
