Model 7620 W IDE -B AND T RANSCONDUCTANCE A MPLIFIER Highest Performance, Range and Accuracy Available for any Amplifier Today! Guildline's 7620 Transconductance Amplifier is a very wide band Transconductance Amplifier. By connecting the output from a stable voltage source to the 7620, it is capable of producing outputs up to 20 A over a specified frequency range of DC to 100 kHz. The 7620 provides the capability of calibrating any device requiring a known stable source of current up to 20 A, such as current shunts and current meters. The Transconductance Amplifier has been designed to satisfy a growing need for AC current measurement of power harmonics in power distribution systems. The output of the 7620 uses a unique patented multi cell array, developed at The National Institute of Standards and Technology (NIST). This output array is extremely stable, with a zero drift of less than 50 ppm/hour at 20 A at 30 kHz. 7620 FEATURES The 7620 offers an impressive 10 V output compliance voltage Stability <10 ppm/hour @ 30 kHz at D.C. and low frequencies, reducing to 5 V at 100 kHz. A front Ranges, (6) 200 A to 20A panel display indicates the compliance voltage existing at the output at all times. Three compliance LEDs indicate the Frequency DC to 1 MHz operating output current and frequency band in use. Compliance to 10 Volts The 7620 Allows Calibration of Devices requiring Guarded Output a Known Stable Source of Current up to 20 A and IEE$-488 Interface provides an amazing 100 kHz to 20 Amperes and Over Voltage and Over Current Protection 1 MHz to 8 Amperes! Input errors have been eliminated by providing the unit with a four terminal input. This enables the 7620 to be easily connected to most accurate 4-wire sensing voltage sources. One of the main sources of error in mak
