Lambda Exclusive Promotion:
Additional 12 months warranty for free (2 years total) via our UK Service Centre.

The Stanford Research Systems DB64 Coax Delay Box provides switch-controlled delays from 0 to 63.5 ns with 0.5 ns resolution. Applications include the timing of photomultiplier coincidences, set-up of time-to-amplitude converters, adjustment of signal phase, or any application which requires an adjustable, high-bandwidth analog delay.

The interchangeable inputs/outputs are on BNC connectors. Internally, the delay line segments consist of accurate lengths of RG58A/U coax cable with 50 Ω characteristic impedance. DPDT switches are used to insert or remove delay segments. Careful component selection, mechanical design, and PCB layout ensure low reflections and low switch feed-through for high speed signals. Two DB64s can be mounted side-by-side in a 19” rack using the RM1U rack mount accessory. A chassis lug is provided on the rear panel as a safety ground.
