Stanford Research Systems

The DG535 Digital Delay/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.

Delay Outputs

There are four delay output channels: A, B, C and D. The logic

transitions of these outputs can be delayed from an internal or

external trigger by up to 1000 seconds in 5 ps increments.

The T0 pulse, which marks the beginning of a timing cycle, is

generated by the trigger signal. The insertion delay between

an external trigger and the T0 pulse is about 85 ns.

Delays for each channel may be “linked” to T0 or any of the

other delay channels. For instance, you can specify the delays

of the four channels as:

· Four independent delay channels

· Two fully-defined pulse channels

· 5 ps delay resolution

· <100 ps rms jitter

· Adjustable amplitude and offset

· Delays up to 1000 seconds

· 1 MHz maximum trigger rate

· Standard GPIB interface

· Optional ±32 V outputs

· DG535 ... $4195
