Digital Gamma-Ray Spectrometer
60
The actual response record may be a combination of any of the above records depending on
the warning conditions. For example:
%000048081<CR>
Amplifier not PZ’d and high voltage disabled.
START_OPTIMIZE
Starts optimization of PZ and flattop correction for all rise times.
START_PZADJUST_AUTO
Starts the automatic PZ process. The automatic PZ is not complete until indicated by the auto
PZ status bit. This bit is returned by the SHOW_STATUS command. Spectral data can be
corrupted if automatic PZ is initiated while a device is collecting data.
Execution Errors:
%131136084<CR>
The command was attempted while the amplifier was set for
a transistor reset preamplifier. No action was taken.
STEP_OUTPUT
[0]
Causes a pulse to be output on the Change Sample output port. The level of the Change
Sample output is changed then returned to the level present when the STEP_OUTPUT
command is received. The duration of the intermediate level varies but is never less than 2 µs.
Use the SET_OUTPUT_HIGH or SET_OUTPUT_LOW commands to establish an initial
output level.
Responses:
$C00000087<CR>
The initial and final level on Change Sample was low.
$C00001088<CR>
The initial and final level on Change Sample was high.
STOP
[seg-mask]
Stops the acquisition of spectral data. The optional segment mask is provided for
compatibility with other MCBs and may be any value from 0 to 65535 but is ignored.
Execution Warnings:
%000005074
Acquisition already stopped (no changes made).
STOP_OPTIMIZE
Stops the optimization in progress. The DSPEC may be in an indeterminate mode. See also
START_OPTIMIZE.
STOP_PZ_AUTOMATIC
Stops the optimization in progress. The DSPEC may be in an indeterminate mode. See also
START_PZ_AUTOMATIC.
