MI 2701A Transconductance Amplifier

The MI 2701A Transconductance Amplifier was originally developed for use in the 2100 series power calibration and DC resistance measuring systems.

Fully programmable, the MI 2701A Transconductance Amplifier can is configurable as part of a fully automatic power calibration system to optimize throughput and will drive resistive, capacitive and inductive loads. When used as a Transconductance Amplifier, the Model 2701A converts a voltage signal applied to the input, in a high resolution output current whose value is directly proportional to the input signal level. It has 3 ranges of 5, 20 and 100 amps.

In DC or source mode, the model 2701A is bipolar. Select the source voltage via the IEEE488 interface on the front panel. And generate the DC voltage from a 16 bit DAC. The 2701A uses fast connecting high current female terminals for the DC output connections.


You can produce outputs of 100 Amps over a frequency range of DC up to 1000 Hz. A large vacuum fluorescent display indicates both the source and amplifier modes. Select these modes selected using the front panel keyboard. The selected current is displayed when in source or DC mode. You can mount the MI 2701A in a rack in a standard 433 mm cabinet. The outputs for the 2701A are located at the rear of the instrument. Two separate outputs provide AC, five way binding posts up to 20 amps and quick disconnect high current female terminals from 20 to 100 amps.

Applications of the MI 2701A include measuring systems such as Model 6010-100A resistance measuring system and Model 2100A and 2100B power calibration systems.
