A.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<cr>

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<cr>”). 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}

<cr><lf> {End of transmission}

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}

RSS: nn {n = current Received Signal Strength}

Stored Faults: {None/Signal Fault/LO Fault/LO Fault, Signal Fault}

Reference: {Internal/External}

<cr><lf> {End of transmission}

A.8 Set Channel Command (S, P1:1, P1:8)

This command changes the Current Channel and thus the Gain and Frequency of the converter to

one of the 30 preprogrammed channels. The command is as follows:

@01/SETCHANcc<cr>

Where ‘cc’ represents a channel number from 01 - 30.

If successful, the converter will return the following string:

For Upconverter:
