Tektronix 7A42 Features:

  • Bandwidth: 350 MHz 
  • Deflection: 0.1 / 0.2 / 0.5 V/Div (TTL mode),  20 / 50 / 100 mV/Div (ECL mode), each direct or through 10:1 probe
  • Input impedance: 1MΩ or 50 Ω 
  • Max. input voltage: at 1 MΩ: 25 V DC+peak AC below 36 MHz, down to 3 V AC at 300 MHz,  at 50Ω: 5 V RMS during any 1 ms interval
  • Trigger level: -1.27 to +1.28 V (TTL mode) in 10 mV steps,  -254 mV to +256 mV (ECL mode) in 2 mV steps (or ×10)
  • Hysteresis: 40 mV (TTL), 8 mV (ECL) (or ×10) 
  • NiCd battery to preserve front-panel control status

The Tektronix 7A42 is a four-channel 350 MHz plug-in for 7000-series scopes. It was specifically designed for logic signals (TTL, ECL, CMOS) and supports triggering based on Boolean conditions of the four inputs. A fifth trace, "Trigger View", displays the trigger function output or external clock input.
