Common Intput and Outputs
Remote Inhibit A logic Low or High contact closure input to inhibit the outputs
External Amplitude Modulation 0 to 5 VRMS provides 0 to 20% output amplitude modulation (±2% of full scale output).
External Drive Input Acts as Amplifier, 0 to 5 VRMS (DC to 5 kHz) or ±5 VDC input for zero to full scale programmed voltage output (±2% of full scale output). Individual inputs for an external signal for each of the three phases.
Remote Programming Voltage 0 to ±7.07 VDC provides zero to full scale programmed voltage output
(±2% of full scale output).
External Input Impedance 40K (ohm symbol) for each of the three inputs.
Externaly Sync External Sync allows the output frequency of the AC source to be synchronized to an external TTL level clock signal.
LKM Clock and Lock Master. Enables synchronizing outputs of two or more California Instruments sources, one acts as master.
LKS Clock and Lock Auxiliary
Front Panel Trigger, BNC Connector Output available at the front panel BNC connector that provides a negative going pulse for any programmed voltage or frequency change. The trigger can be reassigned as an output when running list transients.
Front Panel Phase A, B and C, BNC connectors These three outputs are representive of the programmed output waveform, magnitude and frequency. 0 to 4.86 Vrms represents 0 to a full-scale output voltage.
