==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 V<sub>RMS</sub>, 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). | |||
