SET_MODE_LIST
Puts the unit in List mode as opposed to InSight or PHA Mode. In List mode, individual peak
values are stored along with the time the pulse arrived are stored and transferred to memory.
See SET_MODE_PHA and SET_MODE_SAMPLE.
SET_MODE_PHA
This command sets the MCB to pulse height analysis mode for collection of histogram data.
SET_MODE_SAMPLE
Starts the InSight Virtual Oscilloscope mode.
SET_ROI start_chan,number_of_chans
Sets the ROI flags for the specified channels. This command can be used multiple times to
set ROI flags without affecting previously set flags.
SET_ROI_SAMPLE num
Selects which controls signals are displayed as an ROI on the captured waveform. Only a
single bit can be turned on at a time. The following signals can be selected with the
associated
bit.
Bit 0: Reserved
Bit 1: Reserved
Bit 2: Reserved
Bit 3: LLD
Bit 4: Busy
Bit 5: Gate
Bit 6: Reserved
Bit 7: Peak detect
Bit 8: Reserved
SET_SEGMENT
Not used; included for backward compatibility. This command executes SET_WINDOW,
resetting the window of interest to the maximum number of channels.
SET_SHAP value
Sets the shaping time to the setting indexed by ‘value’. The LIST_SHAP command gives a
list of shaping times. The SET_SHAP command indexes into that list to set the shaping time.
For example, if the result of the LIST_SHAP is:
SHAPING 75 100 125 150 175 200
then the following SET_SHAP commands are valid:
SET_SHAP 0 Sets the shaping time to 0.75 ìs (75 × 10 ns)
SET_SHAP 1 Sets the shaping time to 1 ìs
