### Glossary

Measurement device – external device which is presented as Delphi frame in the program and communicate through standard set of commands with interpreter. Only for measurement purposes. Two types – 2D (or serial mode) and 3D (or package mode), as in multi channel ADC card vs oscilloscope. Names – three characters.

2D (or serial mode) measurement device – offers separate channels (one or more). Typically – ADC card or one channel of oscilloscope. Each ADC /measurement channel is responsible for different external parameter.

3D measurement device – offers an array of values which can be proceed as ensemble. 3D type of multi-channel device means that you can have more than one spectrum at one shot (e.g. different channels of the oscilloscope).

Control device – offers typically one channel; optionally multi-channels control over some external parameter(s). Calibration for using absolute and relative units can be set. Names – three letters.

Synchronisation (sinchro) device – all the measurements are synchronised optionally with this device. Could be used for temporally pause or abort of measurement sequence (scanning). Reserved script name -"Snh".

Interpreter – part of the program, which interprets the script, commands coming from the procedures or elsewhere, call the respective device functions and send back the result. For general commands - reserved script name "Itr".

Procedures – usually dialog boxes with options for later execution of sequences of commands to the devices with results typically presented in TheoPlot.

TheoPlot – chart component presenting GC/MS or MS, with some options for data processing.
