6. COMMANDS AND RESPONSES
33
SET_DEVICE
device
This command is provided for compatibility with the Model 919. Only device number 1 is
valid for a DSPEC.
SET_DSP
num, command,value
This is a debugging command that can be used to directly modify parameters within the
digital signal processor chips. Num (1–4) selects the DSP chip that will receive the
command; command (0–7) indicates which parameter will be changed; and value (–8388608
to 8388607 or –1.0 to 1.0) specifies the new value as either a 24-bit signed integer or a
floating point value. See also SHOW_DSP.
Execution Errors:
%131132080<CR>
There are three parameters.
%131128085<CR>
The first parameter is incorrect.
%131129086<CR>
The second parameter is incorrect.
%131130078<CR>
The third parameter is incorrect.
SET_GAIN_ADJUSTMENT
value
Sets the gain stabilization adjustment to an arbitrary value from –65535 to 65535. This
adjustment is usually made only by the gain stabilizer, and reset to 0 with the
INITIALIZE_GAIN_STABILIZATION command. See also
SHOW_GAIN_ADJUSTMENT.
Execution Errors:
%131134082<CR>
The command was attempted when the currently selected device
was other than device 1.
SET_GAIN_CHANNEL
chan
Sets the center channel for the stabilizer gain peak. If a gain channel is chosen such that the
beginning channel or ending channel would be below channel 0 or above the maximum
channel as determined by the conversion gain, the gain peak width is reduced until the peak
fits the device boundaries. A gain channel and width must be set before gain stabilization can
be enabled.
Execution Errors:
%131128085<CR>
The specified channel number would create a peak that was less
than the minimum width (3 channels) or would be outside the
device’s range.
%131136084<CR>
The command was attempted while gain stabilization was enabled.
SET_GAIN_COARSE
num
This sets the coarse gain to num, which must be one of the following: 1, 2, 5, 10, 20, 50,
100. See also SHOW_GAIN_COARSE.
