The '''Tektronix 134''' current probe amplifier interfaces a [[P6019]], [[P6020]], [[P6021]] or [[P6022]] current probe to the voltage input of an oscilloscope. It also has a VOLTS ONLY setting of the input attenuator switch that provides a voltage gain of 125 or 50, depending on the position of the probe selector switch, with a 50 Ω input impedance. 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. | The '''Tektronix 134''' current probe amplifier interfaces a [[P6019]], [[P6020]], [[P6021]] or [[P6022]] current probe to the voltage input of an oscilloscope.
