Series ATE power supplies are precision analog-controlled power supplies. They feature high gain and zeroable offsets to follow voltage signals or variable resistance controls precisely. An optional fast mode provides fast programming response into the mid audio range. The voltage and current channels are equally controllable with automatic crossover between modes. Panel mounted analog meters allow monitoring of both channels. Optionally, ATE models can be provided with digital displays. To specify, substitute the suffix "DM" for the suffix"M" in the model number. For example: ATE 36-15DM specifies digital displays. Local control of both channels is by panel-mounted 10-turn rheostats. Optionally, the front panel knobs can be replaced with locking-type screw-driver-adjustable controls by specifying models with suffix "L." Panel mounted LEDs indicate voltage or current mode operation. This information is simultaneously delivered as an optically isolated TTL-compatible flag signal accessible through the rear connector. The tabulation of the effective series resistance and inductance in voltage mode and the effective shunt resistance and shunt capacitance in current mode, is done to allow a calculation of the output impedance versus frequency. Series ATE is available in the following Models:
