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:
t

At =t T0 t+ t0.00125000
Bt=tAt +t0.00000005
Ct=tT0t+t0.10000000t
Dt= Ct +t 0.00100000
