IMG Board
The IMG board operates Agilent IMG-100 and IMG-300 gauges and allows you to set gauge
sensitivity value, and gas correction factor. The UHV range is standard, as is remote I/O
control of emission and 0 to 10 V analog output.

Item Description
Supported Gauge Heads Agilent IMG-100, IMG-300
Measurement Range* 1.0E-12 to 1.0E-02 Torr * (or equiv mbar and Pa)
* This represents the ability of the controller to display pressure
values and not the capability of the gauge heads to accurately
measure pressure.
Sensitivity Input Range 00.1 to 99.9
Gas Correction Factor Range 0.1 to 9.9
Analog Output
❑ Range: 0-10 VDC
❑ Slope: 1 V per decade log
❑ Characteristic: output voltage = Log (Pressure) + 11
❑ Output when gauge OFF or Error = 10 V
❑ Load Impedance: >10 kOhms
❑ Response Time:
❑ SLOW - 250 msec
❑ FAST - 10 msec
Error Detection Over Temperature
Gauge Connector SHV
Remote I/O Connector
❑ Connector: 6 pin IEEE 1394 (Firewire type)
❑ Input for Emission on/off is user selectable to be either Active
LO or Active HI. Driving the input to the active state will turn
on the gauge.
❑ HI = +5 V max, 2.4 V min
❑ LO = 0.8 V max, 0 V min
❑ Status Output goes HI during error condition
❑ Analog Output
Allowable Cable Length up to 300’ using RG59U
