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.
Specifications
- 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: 1 MΩ or 50 Ω
- Max. input voltage at 1 MΩ: 25 V DC+peak AC below 36 MHz, down to 3 VAC at 300 MHz
- Max. input voltage at 50 Ω: 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
- Weight: 2.8 kg / 6.2 lb
