7.5.1 MA4061B Upconverter Detailed Command Descriptions and System Responses
This section defines each of the command codes and the associated parameters for the MA4061B
Upconverter module.
FL - Load Frequency
Description: Loads the frequency for the specified module.
Parameters: Desired frequency in MHz, in the form XXXX.XXXX. Leading zeros are optional, but not required. The
decimal point and four trailing characters are required. Valid input frequencies are between 2500.0000
MHz and 2686.0000 MHz. Valid trailing characters are multiples of 0.0625 MHz, all others will be
denied.
Example:
*999<sp>A<sp>FL<sp>2500.0625<sp>CRC<cr>
Response:
OK or MOD or ERR or CRC
AI
- Set IF Attenuation
Description: Sets the IF attenuation for the specified module.
Parameters: Desired IF attenuation in dB, in the form XX.XX. Leading zeros are optional, but not required. The
decimal point and two trailing characters are required. Valid attenuation values are between 0 dB and
25 dB in 0.25 dB steps. Valid trailing characters are 00, 25, 50 or 75.
Example:
*999<sp>A<sp>AI<sp>10.50<sp>CRC<cr>
Response: OK or MOD or ERR or CRC
AR
- Set RF Attenuation
Description: Sets the RF attenuation for the specified module.
Parameters: Desired RF output attenuation in dB, in the form XX.XX. Leading zeros are optional, but not required.
The decimal point and two trailing characters are required. Valid attenuation values are between 0 dB
and 39.75 dB in 0.25 dB steps. Valid trailing characters are 00, 25, 50 or 75.
Example: *999<sp>A<sp>AR<sp>4.25<sp>CRC<cr>
Response: OK or MOD or ERR or CRC
ITS - Set IF Threshold
Description: Sets the IF thresholds for the specified module.
Parameters: Desired IF thresholds in dB, in the form X.X<sp>-X.X. Leading zeros are optional, but not required. The
decimal point and trailing character is required. The first parameter is the positive threshold and can
range between 4.0 and 0.0 dB. The second parameter is the negative threshold and can range
between 0.0 and -4.0 dB. The trailing character can range between 0.0 and 0.9.
Example:
*999<sp>A<sp>ITS<sp>1.5<sp>-1.5<sp>CRC<cr>
Response:
OK or MOD or ERR or CRC
ITE - Enable IF Threshold
Description: Enables IF Threshold detection for the specified module.
Parameters: None
Example: *999<sp>A<sp>ITE<sp>CRC<cr>
Response: OK or MOD or ERR or CRC
