The Tektronix 5A24 is an amplifier plug-in for 5000-series scopes. The deflection range is 50 mV/div to 1 V/div. The maximum bandwidth is 2 MHz.

The 5A24 contains an area on its printed circuit board that has empty solder pads. The user can add custom circuitry that accesses the input signal, output to scope, and power rails.

The 5A24N is the least expensive plug-in Tektronix ever made, priced US$25 in the 1973 catalog (~$140 in 2018 value). The vertical signal path of the 5A24N is basically just an NPN emitter-follower.
