• Notes
• The Tektronix Model 84 Plug-In Test Unit is used with Tektronix 580-series oscilloscopes, providing a reference signal for setting the oscilloscope vertical amplifier gain, a fast voltage step for adjusting oscilloscope vertical amplifier transient response, and a load bank which loads the oscilloscope power supplies over their full current range. It allows a check of the DC balance of the oscilloscope vertical amplifier and may also be fed external signals which might be used in calibration procedures.
  The Type 84 underwent a model number change occurring at serial number 794; previously it was designated 067-0523-00 Calibration Fixture. Both unit designations are electrically identical.
