STANFORD RESEARCH SYSTEMS DG645 4/8 Ch Digital Delay/Pulse Generator


General description of the used STANFORD RESEARCH SYSTEMS DG645 for sale.
The SRS DG645 is a versatile digital delay/pulse generator that provides precisely defined pulses at repetition rates up to 10 MHz. The instrument offers several improvements over older designs — lower jitter, higher accuracy, faster trigger rates, and more outputs. The DG645 also has Ethernet, GPIB and RS-232 interfaces for computer or network control of the instrument. The SRS DG645 eliminates timing indeterminacy by measuring the timing of triggers with respect to the internal clock and compensating the analog delays. This approach reduces the jitter by about 100× and allows the internal rate generator to operate at any rate - not just a sub-multiple of the clock frequency. Specifications. Delay Channels: 4 independent pulses controlled in position and width. 8 delay channels (optional). Range: 0 to 2000 s. Resolution: 5 ps. Accuracy: 1 ns + (timebase error × delay). Trigger delay: 85 ns (ext. trig. to T0 output). External Trigger Rate: DC to 1/(100 ns + longest delay), (maximum of 10 MHz). Threshold: ±3.50 VDC. Internal Rate Generator Trigger modes: Continuous, line or single shot. Rate: 100 µHz to 10 MHz. Resolution: 1 µHz. Option 01, Eight delay channels (5 V) . Option 02, Eight delay channels (30 V). Option 03, Combinatorial outputs. Option 04, OCXO timebase. Option 05, Rubidium timebase.
