at the left upper portion of the screen.
Serial Number
Provides the unit serial number.
Model Number
Provides the model number of the unit.
Firmware Version
Provides the version of firmware that is running on the unit.
Temperature
Temperature
Displays the temperature of the unit in degrees C.
Fan Speed

automatically increases or decreases to control the overall temperature.
Power Supply
Drain Voltage
Displays the analog output voltage from the internal power supply.
Drain Current
Displays the analog output current from the internal power supply.
Unit Led

[On/Off]. Displays the status of the u
nit’s amplifier
RF
RF Input Power
Where applicable, displays the input power level in dBm.
RF Forward Power
Where applicable, displays the analog RF forward power level (output) in dBm.
Note that for RF forward power readings below 25 dBm, the forward power may
not read accurately.
RF Reflected Power
Where applicable, reads the analog RF reflected power level (reflected back into
unit). The approximate output power in dBm is displayed. For RF reflected power
readings below 25 dBm, the forward power may not read accurately.
Step Attenuation
Where applicable, displays the gain attenuation.
