Rear interface

The SC504 has dedicated rear interface signal inputs switchable from the front panel AC/DC/GND/Int DC coupling selectors. These are terminated in 50 Ω (max.5 VRMS, 0.5 W).

Additionally, it provides a trigger input, Z-axis input (±5 V), delayed gate input (ECL), gate select input (ground for ext gate), intensify input (ECL), Ch1 trigger output (>50 mV/Div, 30 MHz), triggered gate output (ECL), holdoff output (ECL), and ramp output (0−10 V).

Internals

The SC504 uses some custom Tek ICs, namely the 155-0124-00 preamplifier (U4345), 155-0109-01 trigger (U3238), and 155-0122-00 A-B logic (U3158).
