• Exc Active: (Off or On) When on, this exciter is on the air.

• RF Present: (Off or On) This is an indication that the RF level at the output of the ex-

citer is above a given threshold level. The RF presence threshold is an RF output level

of approximately 5 mW.

• Board Type: (UHF or VHF) Interface configured to fit existing UHF and VHF exciter

interface connections.

• Board Rev: This is the board revision for the External I/O board.

• CPLD Rev: This is the software revision level of the CPLD in the External I/O board.

• EEPROM: (Ok or FAULT) The EEPROM is the local board memory. It stores board

specific information such as board type, board revision, CPLD revision, and other lo-

cal data.

Analog loopback: Choices are Enabled or Disabled. Disabled is the normal setting.

• This function loops an analog output back through an analog input channel for diag-

nostics purposes.

The last two screen entries are Analog Output A and Analog Output B. These two entries

provide a voltage for the analog loopback test mentioned above.

• Analog Output A is looped back through analog Analog 1 and 3 inputs and Analog

Output B is looped back through Analog 2 and 4 inputs, see external I/O Board screen

Figure 3-25 for the analog inputs.
