4600 WaveTek Transconductance Amplifier

Wavetek 4600 Features:

• Extends calibrator currents to 11A DC & AC RMS
• Slave mode programmable from 4708,4700 & 4705
• Solo mode operation for general application
• AC performance from 10 Hz to 20 kHz
• Solo Mode:
  • Converting a voltage input to a current output, with a transfer characteristic of 1 Amp DC or AC output for 1 V DC or AC input, it may be coupled to any convenient voltage source
  • With total 90 day, ± 1 °C accuracies to ± 125 ppm (DC currents from 0 to 11A) and ±430 ppm (AC currents from 0.9 to 11A at frequencies from 10 Hz to 5 kHz)
  • Slave Mode: Used in conjunction with a compatible model 4707, 4700 or 4705, two cables connect the Transconductance Amplifier to the Calibrator. 
• Total Uncertainty Relative to Voltage Source:
  • 90 day, 23°± 1°C±80 ppm output ±500uA
• Input Impedance:
  • 300k Ohm
  • AC Current
• Total Uncertainty Relative to Voltage Source:
  • 90 day, 23°± 1°C, ±(330 ppm output + 1.1 mA)
  • 10 Hz-1 kHz. ±(0.1 % output + 1.4 mA) 1-5 kHz
• Distortion:
  • 0.2% (10 Hz-1 kHz), 0.5% (1-5 kHz)
• Input Impedance:
  • 300k Ohm in parallel with 100 pF

The Waketek 4600 Transconductance Amplifier extends the current sourcing capabilities of the Datron range of Multifunction Calibrators and Standards to 11A DC or RMS AC.

The first cable is fully shielded and carries the analog voltage from the rear panel of the Calibrator to the rear panel of the Amplifier. A digital cable carries control signals between the two rear panels enabling the Calibrator to automatically determine the presence of the Amplifier, and control it. The 10A range of the Calibrator is then enabled, and the user is able to program the required current output from the front panel or IEEE-488 interface of the Calibrator.
