Distortion below -60 dB
Ethernet / IEEE-488.2 and USB interfaces


The 7810 series of Transconductance amplifiers is the latest innovation for high current, wide bandwidth AC current outputs. It operates from DC to 100kHz with very low distortion. By connecting the output from a stable voltage source, the 7810 is capable of producing currents up to either 50A or 100A over a specified frequency range of DC to 100kHz.

Automated and user friendly

With an embedded Windows 10 computer and touch sensitive colour screen, the 7810 Transconductance Amplifier is very easy to use. It can calibrate any device requiring a known stable source of AC current up to 100A, manually or via automation. The transconductance amplifier satisfies AC current measurement requirements at power frequencies and at higher frequencies up to 100kHz.

The output current from the 7810 Transconductance Amplifier is based on a unique patented multi cell current source array developed at Guildline Instruments. This output array is extremely stable, with zero drift of less than 50 ppm/hour at 100 A at 100 kHz. The 7810 also offers an impressive 7 to 9 V output compliance voltage.
