Stanford Research SRS DG535 Digital Delay/Pulse Generator with GPIB and Option 02 Key Features: -Four delay channels -Two pulse channels -5 ps delay resolution -< 100 ps rms jitter -Adjustable amplitude & offset -Delays up to 1000 seconds -Standard GPIB interface Description: The DG535 Digital Delay and Pulse Generator provides four precisely-timed logic transitions or two independent pulse outputs. The delay resolution on all channels is 5 ps, and the channel-to-channel jitter is typically 50 ps. Front-panel BNC outputs deliver TTL, ECL, NIM or variable level (-3 to +4 V) pulses into 50 Ω or high impedance loads. The high accuracy, low jitter, and wide delay range make the DG535 ideal for laser timing systems, automated testing, and precision pulse applications.
