Stanford Research Systems SIM922A Overview
The SIM922A Diode Monitor continuously reads a single sensor and provides both digital and analog outputs. Based on the modular SIM platform, it provides high performance capability in a small footprint. The SIM922A has a programmable, precision 10 A current source to provide sensor excitation. Results can be displayed in either kelvins or volts. The SIM922A employs four-wire measurement circuits (ToneI excitation leads, V sense leads), making readings insensitive to series lead resistance. Sensor excitations can be disabled to reduce power dissipation at sensitive cryogenic stages. Measurements are performed at five readings per second. The scaled analog output (Tone10 V) produces a voltage proportional to measured temperature, with a full-scale range from 10 K to 1000 K. A relative-mode button subtracts the last absolute reading prior to scaling, to provide expanded resolution for temperature deviations.
