writes the complete detector setup (including configuration, trimbits, flat field coefficients, badchannels etc.) is a set of files for which the extension is automatically generated

online

return whether the detector is in online (1) or offline (0) state.

status

gets the detector status - can be: running, error, transmitting, finished, waiting or idle

data

gets all data from the detector (if any) processes them and writes them to file according to the preferences already setup

frame

gets a single frame from the detector (if any) processes it and writes it to file according to the preferences already setup

hostname

Gets the detector hostname (or IP address)

caldir

Gets path of the calibration files

trimdir

Gets path of the trim files

outdir

directory to which the files will be written by default

extsig:i

Gets usage of the external digital signal i. The return value can be: off, gate_in_active_high, gate_in_active_low, trigger_in_rising_edge, trigger_in_falling_edge, ro_trigger_in_rising_edge, ro_trigger_in_falling_edge, gate_out_active_high, gate_out_active_low, trigger_out_rising_edge, trigger_out_falling_edge, ro_trigger_out_rising_edge, ro_trigger_out_falling_edge

timing

Sets the timing mode of the detector. Can be auto, gating (works only if at least one of the signals is configured as gate_in), trigger (works only if at least one of the signals is configured as trigger_in), ro_trigger (works only if at least one of the signals is configured as ro_trigger_in), triggered_gating (works only if one ofthe signals is configured as gate_in and one as trigger_in).

Gets the number of cycles (e.g. number of triggers)

probes

Gets the number of probes to accumulate (max 3)

timestamp

Gets the internal time stamp of the nex frame acquired (i.e. during an acquisition, all timestamps of the frames are stored in a FIFO which can be read after the acquisition - returns -1 if the FIFO is empty)

dr

Gets the dynamic range

trim:mode fname

Trims the detector and writes the trimfile fname.snxxx. mode can be: noise beam improve fix offline - Check that the start conditions are OK!!!

flatfield

fname returns whether the flat field corrections are enabled and if so writes the coefficients to the specified filename. If fname is none it is not written

ratecorr

returns wether the rate corrections are enabled and what is the dead time used in ns

badchannels fname

returns wether the bad channels corrections are enabled and if so writes the bad channels to the specified filename. If fname is none it is not written

angconv fname

returns wether the angular conversion is enabled and if so writes the angular conversion coefficients to the specified filename. If fname is none, it is not written

globaloff

returns the fixed angular offset of your encoder - should be almost constant!

fineoff

returns a possible angualr offset of your setup - should be small but can be senseful to modify

binsize

returns the binning size of the angular conversion

angdir

gets the angular direction of the detector (can be 1 or -1 - by default 1, channel 0 is smaller angle)

positions

returns the number of positions at which the detector is moved during the acquisition and their values

startscript script

sets a script to be executed at the beginning of the measurements (e.g. open shutter). none unsets. Parameters will be parsed as script nrun=i par=spar where i is the run number and spar is the value of startscriptpar.

stopscript

returns the script to be executed at the end of the measurement (e.g. close shutter). none unsets. Parameters will be parsed as script nrun=i par=spar where i is the run number and spar is the value of stopscriptpar.

startscriptpar

returns the parameter passed to the start script as string with the syntax par=spar. Its meaning must be interpreted inside the script!

stopscriptpar

returns the parameter passed to the start script as string with the syntax par=spar. Its meaning must be interpreted inside the script!

scan0script

returns the scan script to be executed at higher level. Script can be none (unset), threshold (change threshold DAC values for all modules), energy (change energy threshold DAC values using calibration for each module), trimbits (change trimbits for all channels) or any script (e.g changing temperature or moving sample) which will be called with the syntax script nrun=i fn=fname var=val par=spar where i is the file index, fname is the file name val is the current value of the scan variable and spar is the value of the scan parameter

scan1script

returns the scan script to be executed at lower level. Script can be none (unset), threshold (change threshold DAC values for all modules), energy (change energy threshold DAC values using calibration for each module), trimbits (change trimbits for all channels) or any script (e.g changing temperature or moving sample) which will be called with the syntax script nrun=i fn=fname var=val par=spar where i is the file index, fname is the file name val is the current value of the scan variable and spar is the value of the scan parameter
