List Price is: $38,500.00 from Guildline (60 Day Delivery Time) The Unit's Serial Number Tag Reads: Serial Number: 60 825 Features: Stability < 10 ppm/hour @ 30 kHz Ranges, (6) 200 µA to 20 A Frequency DC to 1 MHz Compliance 10 volts Guarded output IEEE 488 Interface Over voltage & over current protection Description: Guildline Model 7620 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 amps over a specified frequency range of DC to 100 kHz, and a usable frequency range extending to 1 MHz. The 7620 provides the capability of calibrating any device requiring a known stable source of current up to 20 amps, 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 amps at 30 kHz. The 7620 offers an impressive 10 volts output compliance voltage at D.C. and low frequencies, reducing to 5 volts at 100 kHz. A front panel display indicates the compliance voltage existing at the output at all times. Three compliance LEDs indicate the operating output current and frequency band in use. The 7620 is intended to calibrate devices requiring a known stable source of current up to 20 amps. 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 making current measurements is the leakage between the HI and LO terminals of the current source. To alleviate this condition, the 7620 has a driven output guard which provides a buffered signal whose potential follows that of the output HI. The 7620 is fully programmable over the IEEE 488 General Purpose Interface Bus. The Bus address is selectable from the rear panel, and all front panel controls can be duplicated over the Bus with the exception of power on/off. A sophisticated overload detection system is implemented on the unit to control and indicate when the 7620 is operating within its specified limits. It is also possible to operate the unit outside the specification but within its safe limits by disabling part of the protection system. In this case, information is still provided to the front panel and over the Bus as the status of the instrument.
