Appendix C SFC1800A Synthesized Frequency Upconverter
C-10 TM111 – Rev. 1.0
If successful, the converter will return the following string:
For Upconverter:
Channel: cc
{cc = current channel number, 01 to 30}
Frequency: ffff.fff {ffff.fff = frequency in MHz}
Gain: sgg.g {s = ± and gg.g = gain in dB}
Input Atten: aa dB {aa = input attenuation}
Stored Faults: {None/Signal Fault/LO Fault/LO Fault, Signal Fault}
Reference: {Internal/External}
{End of transmission}
For Upconverter:
Channel: cc
{cc = current channel number, 01 to 30}
Frequency: ffff.fff {ffff.fff = frequency in MHz}
Stored Faults: {None/Signal Fault/LO Fault/LO Fault, Signal Fault}
Reference: {Internal/External}
{End of transmission}
C.7 Set Current Channel Gain Command (S, P1:1, P1:8)
This command alters the stored Gain of the current channel. The command is as follows:
@01/SETGAINsgg.g
The numeric value ‘s’ indicates the ‘plus’ sign (+) or ‘minus’ sign (-). The numeric value ‘g’
consists of three digits indicating gain. Valid Gain ranges are dependant upon device
configuration: To see range for current configuration, send the setgain command without any data
(i.e. “@SETGAIN”). This will result in an error message being returned that contains the
current gain limits. Gain values outside this range will be responded to by the ‘ILLEGAL GAIN’
prompt.
If successful, the converter will return the following string:
For Upconverter:
Channel: cc
{cc = current channel number, 01 to 30}
Frequency: ffff.fff {ffff.fff = frequency in MHz}
Gain: sgg.g {s = ± and gg.g = gain in dB}
Input Atten: aa dB {aa = input attenuation}
RF: {Off/On}
Stored Faults: {None/Signal Fault/LO Fault/LO Fault, Signal Fault}
Reference: {Internal/External}
{End of transmission}
