SFC6400A/SFC1450A Synthesized Frequency Upconverter Appendix A

TM106 – Rev. 1.1 A-15

A.10 Store Current Channel Settings (S, P1: 1, P1: 8)

This command stores the current settings for the Frequency and Gain into the channel table for the

currently selected channel. The command is as follows:

@01/STORE<cr>

If successful, the converter will return the following string:

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}

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

Reference: {Internal/External}

<cr><lf> {End of transmission}

A.11 RF On/Off Command (Upconverter Only) (All)

These commands control the converter’s output. The commands are as follows:

@01/RFON<cr>

@01/RFOFF<cr>

Note: If the converter is faulted, any attempt to turn on the RF without first clearing the fault

will fail.

If successful, the converter will return the following string:

For backup converter:

Backup RF: {Off/On}

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

<cr><lf> {End of transmission}

For Single or Primary Converter:

RF: {Off/On}

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

<cr><lf> {End of transmission}

A.12 Change Input Attenuation Command (Upconverter Only)(S, P1: 1, P1:

This command alters the converter-input attenuation. The commands are as follows:

@01/SETATTNaa<cr>

Where aa is the input attenuation (00 - 30)
