Note:
1)
The "TSNR", "LID" and "UID" in Table 2 are the measurements of feedback signal quality. This
feedback signal could be from a transmitter or the exciter/translator itself and its input range is -30
dBm to 0 dBm (Recommended range is -15 dBm to -5 dBm). These measurements are derived from
the After-filter Feedback Signal connected to the rear port [RF_IN_A] BNC connector. If there is no
signal connected, these readings will not be available or not valid. The "TSNR" is measured with
equalization on. It takes about 10 seconds to get the first reading on "TSNR", and about 3 seconds to
get the first reading of "LID" and "UID". After averaging, the displayed upper limit on the "TSNR" is
about 39 dB and about 54 DB for the IMD metrics.
2)
The "RSNR" and "RSSI" in Table 3 are status of the signal from the tuner when working in Translator
Mode. And the "RSNR" is measured with equalization on. Therefore if there is no signal connected to
port "RF_IN", these readings will not be available or not valid.
3)
The "CTRL" status in Table 4 indicates "RMT" (Remote) mode or "LCA" (Local) mode. When in
"LCA" mode, the exciter/translator can only be controlled by the front panel interface and when in
"RMT" mode, settings from the front panel keyboard are ignored - with the exception of
"RMT"/"LCA" setting - and while in RMT mode, only commands from remote control interface, such
as the WEB or serial port, are processed.
