MKS Instruments 937B Vacuum Gauge Controller

class pymeasure.instruments.mksinst.mks937b.MKS937B(adapter, name='MKS 937B vacuum gauge controller', address=253, **kwargs)

Bases: Instrument

MKS 937B vacuum gauge controller

Connection to the device is made through an RS232/RS485 serial connection. The communication protocol of this device is as follows:

Query: ‘@<aaa><Command>?;FF’ with the response ‘@<aaa>ACK<Response>;FF’ Set command: ‘@<aaa><Command>!<parameter>;FF’ with the response ‘@<aaa>ACK<Response>;FF’ Above <aaa> is an address from 001 to 254 which can be specified upon initialization. Since ‘;FF’ is not supported by pyvisa as terminator this class overloads the device communication methods.

Parameters

adapter – pyvisa resource name of the instrument or adapter instance
name (string) – The name of the instrument.
address – device address included in every message to the instrument (default=253)
kwargs – Any valid key-word argument for Instrument
