Response to
Query
Command or Query.
Sets or returns Rx Symbol rate in the form xxxx.xxx, where:
xxxx.xxx = value, in ksymbols/sec, from 4.8 ksps to 3.00 Msps
Resolution = 1 sps.
Note: Symbol Rate ranges in IP-ACM from 37ksps to 3000ksps
Example: <0/RSR=2047.999 (2047.999 ksymbols/sec)
Command or Query.
Sets or returns Rx Frequency in the form xxxx.xxxx, where:
For CDM/R-570AL – 950 to 2250 MHz in CDM-570A Compatible Mode (CMO=1)
and 950 to 2000 MHz in CDM-570 Compatible Mode (CMO=0)
For CDM-570A – 50 to 90 and 100 to 180 MHz
Resolution = 100 Hz
Examples:
1) <0/RFQ=0950.9872
2) <0/RFQ=0073.4528
Command or Query.
Sets or returns Invert Receive Data in the form x, where:
0 = Normal
1 = Inverted
Example: <0/RDI=1 (selects Inverted RX Data)
Command or Query.
Sets or returns Rx Spectrum Invert in the form x, where:
0 = Normal
1 = Rx Spectrum Invert
Example: <0/RSI=0 (selects Normal)
Sets or returns Invert Receive Clock in the form x, where
0 = Normal
1 = Rx Spectrum Invert
Command or Query.
Sets or returns Rx Descrambler state in th form x, where:
0 = Off
1 = On (default descrambler type)
2 = On – IESS-315
Note: When CnC mode is ON, Rx Descrambler state is fixed as IESS-315.
Example: <0/RDS=1 (Scrambler On)
