Guildline 7810 Transconductance Amplifier

Guildline Instruments 7810 Wideband Transconductance Amplifier is the latest innovation for High Current, Wide Bandwidth AC Outputs.  The 7810 operates from DC to 1 MHz with very low distortion.  By connecting the output from a stable voltage source, the 7810 is capable of producing outputs up to 100 A over a specified frequency range of DC to 1 MHz. With a touch sensitive screen, the 7810 provides the capability of calibrating any device requiring a known stable source of AC current up to 100 A, manually or via automation.  The Transconductance Amplifier satisfies AC current measurement requirements at power and frequencies up to 1 MHz. The 7810 provides up to 100 Amperes output.  This is based on a Guildline designed, and patent protected, AC source.  The output of the 7810 is based on a unique patented multi cell current source array developed at Guildline Instruments.  This output array is extremely stable, with a zero drift of less than 50 ppm/hour at 100 Amperes at 100 kHz.  The 7810 also offers an impressive 7 to 9 V output compliance voltage.
Guildline’s NEW 7810 Transconductance Amplifier Provides the Latest in New Patented Technology and Innovation – While Achieving Industry Leading Measurement!
To automate testing and calibration setups, the 7810 Series is controllable via the IEEE‑488.2 bus interface, or USB interface.  Additionally, full manual operation is achieved via the embedded Windows Based Computer.  The 7810 has a touch sensitive screen and display capable of providing input control, output control, overload indication and temporary storage of data from manual operation. Uses for the Amplifier include calibration of alternating current (AC) and direct current (DC) shunts and resistors up to 100 A and 1 MHz; and calibration of AC and DC ranges on analogue and digital multimeters.
