4.0 Model 2099-2424 Option W65:
L-Band Inserted 10 MHz Reference Power Adjustment
Option W65 allows the user to independently adjust the power of the 10 MHz signal that is inserted on both
(LNB and SSPB) L-band loop-throughs. NOTE: The maximum 10 MHz input power is +3 dBm when
Option W65 is installed.
There are two methods available for adjusting the power of the 10 MHz signal inserted onto the L-band
Loop-throughs.
1). If the user has selected the internal 10 MHz reference as the source, the user may adjust the output
power LEVEL from -10 to +10 dBm.
2). If the user has selected the external 10 MHz reference as the source [i.e., 10 MHz from the external
reference input (J5)] then the user may adjust the GAIN from -10 to +10 dB from the input level point
to the insertion point. Eg., if the external 10 MHz reference input is +2 dBm and the GAIN is set to
+4 dB then the inserted 10 MHz reference power is +6 dBm.
If the Reference Mode is set to INTERNAL, EXT LOCK, or EXT LOCK AUTO then the front panel menu will
allow the user to adjust the inserted reference LEVEL from -10 to +10 dBm. The Remote M&C commands to
perform these settings are ” {CW} “ (Set SSPB 10 MHz Reference Insert Level) and ” {CY}” (Set LNB 10
MHz Reference Insert Level).
If the Reference Mode is set to EXT PASS or EXT PASS AUTO then the front panel menu will allow the user
to adjust the inserted reference GAIN. The Remote M&C commands to perform these settings are ” {CX} “
(Set SSPB 10 MHz Reference Insert Gain) and ” {CZ}” (Set LNB 10 MHz Reference Insert Gain).
