Measurement Device [MD]


The MD could be one of two kinds: 2D (or serial mode) – e.g. multi-channel ADC or single-channel oscilloscope; or 3D (or package mode)– e.g. multi-channel oscilloscope. ChnIdx (channel index) has different meaning for 2D and 3D MDs.

MD.IniSet

    (re)Initiate the device using loaded in advance setting or hard setting otherwise, the device state after command IniSet is in state "OffLine" . Returns 'OK' or 'Error'.

MD.EnbGet 

    Checks if the device enabled (is it connected and switched on). Return "True" / "False"

MD.EnbSet(B) 

    Switches device to Running / StandBy state (B true/false). Returns 'OK' or 'Error'.

MD.DftSet(ChnIdx)

    Sets default channel of MD to ChnIdx. Returns 'OK' or 'Error'.

MD.ChnGet(ChnIdx)     - 2D (serial mode) MD only

    Measures and returns the value of ChnIdx channel, if ChnIdx is omitted then default channel is assumed.

MD.SpcGet(ChnIdx)

    Measures and puts measured spectrum in the spectrum buffer (package). Returns 'OK' or 'Error'.

    ChnIdx specifies z-channel and it is valid only for 3D (package mode) MD, otherwise (in 2D) ChnIdx is ignored and all 2D channels are transferred into the buffer (the package).

MD.DSmGet

    Sends next spectrum thru open data stream to its plot. Returns 'OK' or 'Error'.

MD.SetLod(FileName)

    Loads from FileName MD's settings if FileName is empty the device will be read for the setting or internal defaults will be loaded. Returns the loaded filename or 'Error'.

MD.SetSav(FileName)

    Saves into FileName MD's settings, if FileName is empty the the last loaded or default setting will be written. Returns the saved filename or 'Error'.

MD.SetGet(FileName)

    Gets back the current setting filename

MD.DimGet(Dim)

    Returns units of measurement, for multi-channel device and you input Dim="Abs”  the command returns for abscissa units (along the spectrum). For multi-channel device N is zChn, otherwise N is a channel number.

    That is one way to check if certain MD is multi-channel, when you ask the device for abscise units, multi-channel device  will return something, but single-channel one will reply with error message.

MD.CmdExe(Command)

    The device interprets this text Command and returns the result as text
