The Tektronix 134 current probe amplifier interfaces a P6019, P6020, P6021 or P6022 current probe to the voltage input of an oscilloscope. It also had a Volts Only setting of the input attenuator switch that provided a voltage gain of 125 or 50, depending on the position of the probe selector switch. It was designed by Hans Springer. Early versions, up thru S/N 6539, had the switch positions labeled only for the P6019 & P6020 probes but these early versions are still compatible with the later P6021 & P6022 probes introduced in 1969.
Each 134 came with its own separate, dedicated power supply using the same Tektronix proprietary coaxial connector as that used in the Type 131s and its power supplies . For more information on the power supplies for the Type 134 see the separate Type 134 Power Supplies page.
