Description of Arguments
to Query
Command or Query. CDM-570L Only
BUC transmit LO frequency information in the form: xxxxxs,
where:
xxxxx is the LO frequency, in the range of 3000 to 65000 MHz
All 0's (000000) disables the feature.
s is the sign for the mix (+ or - character)
Terminal Frequency = BUC LO ± TFQ
Example: BLO = 12000+ (BUC LO is 12 GHz, low-side mix)
Query only. CDM-570L Only
BUC output power level in the form xx.x, where xx.x is the value
in Watts.
Example: BOL=08.3 (BUC reports output power is 8.3 Watts)
Returns 00.0 when FSK and BUC power are not enabled.
Query only. CDM-570L Only
Indicates BUC temperature, in the form: sxx, where:
s = sign (+ or - character)
xx = value
If not available, response is –99
Example: BUT=-13 (BUC temperature is -13 degrees C)
Note: This query is only valid when the FSK and BUC power are
turned On.
Query only. CDM-570L Only
BUC PLL lock state, where:
1=Unlocked
0=Locked
Example: BPA=0 (BUC PLL is locked)
If not available, response is 9
Note: This command is only valid when the FSK and BUC power
are turned On.
