84
The Tektronix Type 84 is a calibration fixture plug-in for 580-series scopes.
It was renamed the 067-0523-00 during production (SN 974+).
The Type 84 provides a calibrated amplitude signal for adjusting gain, a fast-rise voltage step – produced by a mercury switch – for adjusting the impulse response of the vertical amplifiers in the scope, and load resistors to test the power supply of the scope. It also features an external input to connect a time-mark generator during calibration.
