hp 5359A Time Synthesizer (Pulse Generator)

hp 5359A Parts Store


The hp 5359A is essentially a pulse generator. What distinguishes this instrument over typical pulse generators is the ability to provide an ultra-high accuracy, ultra-high resolution time delay (from an external trigger) and an ultra-high accuracy, ultra-high resolution time delay pulse width. The full scale for both time delay and time width is 160 ms with 50 ps resolution. The minimum width is 5 ns and the minimum period is on the order of 100 ns. The internal pulse repetition rate generator (frequency) has less absolute accuracy than the two delay times. The unit can also provide delay and width times using a 2^24 bit system counting external edge events. However, our best understanding (to be reviewed) is that the external event mode does not make use of the high resolution features of the unit, more to follow.

hp 5359A in the August 1978 hp Journal From the hp website: "Cover: Model 5359A Time Synthesizer and Model 5370A Universal Time Interval Counter Universal Counter Resolves Picoseconds in Time Interval Measurements...a new triggered phase-locked oscillator and a dual vernier interpolation scheme provide 20-picosecond resolution without averaging, by David C. Chu, Mark S. Allen, Allen S. Foster, pg 2-11 The Triggered Phase-Locked Oscillator, by David C. Chu, pg 8-9 Time Synthesizer Generates Precise Pulse Widths and Time Delays for Critical Timing Applications...this time synthesizer's extremely stable, low-jitter time delays may be synchronized precisely to an external trigger, by Leonard R. Dickstein, Keith M. Ferguson, pg 12-19"

In 1981, the hp 5339A sold for $7,500. They crossed $10,000 in 1979, and by the last year it was available as a catalog item in 1993, the hp 5359A sold for $17,950.

We acquired a small fleet of these units some years back to construct a time line for a physics experiment. No longer needed, most will now be parted out and/or recycled for precious metals.

All parts, boards, and assemblies are used and in working condition. Here are some preliminary prices:

All prices are subject to change without notice, shipping is an additional charge.

Parts Prices

All boards will be taken from a working unit and/or tested before shipping. Boards and parts are not returnable. Use good trouble-shooting an repair practice. For example, check all power supply rails for both DC and AC ripple before doing any other trouble shooting! Do not put "new" used cards in a unit with power supply problems, until the power supply rails are operating correctly (with the possible exception of the power supply regulator boards).

If you are concerned about physical condition / appearance (e.g. for a Front Panel Assembly), please request a snap-shot of the actual item prior to placing your order and making payment.
