Note:
1)
The RF parameter in the “RF” sub-menu turns the RF output of the exciter/translator ON or OFF.
2)
The POWER parameter specifies the RF output power level in dB (in the range of -25 to +5 dBM,
note: typical exciter/translator output level is 0 dBm).
3)
The "AGC" parameter in the "RF" sub-menu is used to engage or disengage the exciter/translator
system-level automatic gain control. AGC has options "ON" and "OFF". "LVL" and "REF" are
decimal numbers whose range is from 0 to 255. "LVL" is the reading of the DC voltage from Port
[AGC_IN] which reflects the AGC feedback signal level, and "REF" is the reference value (or target)
of the AGC function. When AGC is turned ON for the first time, the "LVL" will be saved
automatically to "REF" as a reference. So if the AGC feedback signal level changes due to
temperature differences or mismatch impedance, etc., the reading of "LVL" will be different from that
of "REF", and the AGC function starts to slowly adjust the output level of the exciter/translator to
approach to the pre-set reference level. The AGC adjustable range is from +1 dB to -10 dB.
