PRODUCT FEATURES

Amplifier Input Configuration Programming 
The 609B-3 can be configured as a noninverting amplifier, an inverting amplifier, or a differential amplifier. The different input configurations are wired into the AMP INPUT receptacle on the rear of the unit.

External Control Connector 
Connections from customer supplied remote switching devices can turn on and off the high-voltage output and/or the AC power to the unit using a multi-pin connector on the rear of the unit.

High-Voltage Switch 
A three-position switch to select ON, OFF or REMOTE.

Power Switch 
A three-position switch to select ON, OFF or REMOTE.

Voltage Monitor 
A buffered output providing a low-voltage replica of the high voltage output.

• Scale 
  1/1000th of the high-voltage output signal.
• DC Accuracy 
  Better than 0.1% of full scale.
• Offset Voltage 
  Less than ±5 mV.
• Output Noise 
  Less than 5 mV rms (measured using the true rms feature of the Hewlett Packard Model 34401A digital multimeter).
• Output Impedance 
  0.1 ohm.
