Command or Query.
Sets or returns Tx Symbol rate in the form xxxx.xxx, where:
xxxx.xxx = 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/TSR=2047.999 (2047.999 ksymbols/sec)
Command or Query.
Sets or returns Tx 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 - 180 MHz
Resolution=100 Hz
Examples:
1) <0/TFQ=0950.9872
2) <0/TFQ=0073.4528
Command or Query.
Sets or returns Invert Transmit Data in the form x, where:
0=Normal
1=Inverted
Example: <0/TDI=1 (selects Inverted TX Data)
Command or Query.
Sets or returns Tx Spectrum Invert selection in the form x, where:
0=Normal,
1=Tx Spectrum Inverted
Example: <0/TSI=0 (normal)
Command or Query.
Sets or returns Tx Scrambler state in the form x, where:
0=Off
1=On (default scrambler type)
2 = On – IESS-315
Note: When CnC mode is ON, Tx Scrambler state is fixed as IESS-315.
Example: <0/TSC=1 (Scrambler On)
