Parameter Storage Commands
MGparam, param: 0.0000 - 2000.0000,?
Description : Electron Multiplier Gain Storage.
Echo: Query Response.
Store a value of electron multiplier (CDEM) Gain, expressed in units of
thousands, in the non-volatile memory of the RGA head.
The command is typically used together with the MV instruction to store
calibrated sets of [High Voltage and gain] for the Electron Multiplier.
Important : The gain is not used internally by the RGA to correct the ion
currents measured with the Electron Multiplier, it is simply stored so it can be
read and used by any host computer connected to the instrument.
As expected, this command is only available in heads with a CDEM option
(Option 01) installed (See MO command for details).
Parameters:
MGparam, param: 0.0000-2000.0000: The parameter, interpreted as a CDEM
gain in units of thousands, is stored in the non-volatile memory of the head.
MG?: Electron Multiplier Gain parameter query.
Error checking:
The absence of a parameter (i. e. MG) is treated as an error.
No default value is available.
A bad-command communications error is reported when this command is
invoked in a unit with no CDEM option installed (See MO command).
MVparam, param: 0 - 2490,?
Description : Electron Multiplier Bias Voltage Storage.
Echo : Query Response
Store a value of Electron Multiplier (CDEM) Bias Voltage, in units of Volts, in
the non-volatile memory of the RGA head.
The command is typically used together with the MG instruction to store
calibrated sets of [Bias Voltage and gain] for the Electron Multiplier.
Important: The voltage value is not used internally by the SRS RGA to set the
bias voltage of the Electron Multiplier, it is simply stored so it can be read and
used by a host computer.
As expected, this command is only available in heads with a CDEM option
installed (See MO command for details).
