It will be advertised until we have a sufficient pool of candidates., we are estimating it will be open about 3 weeks. Please let us know if you have candidates in mind, or any questions. Applications are through the Project Manager link below, not through the Art Program.

I bought a used 5071A and my estimate from looking at the log was that it had run around 300 days previously. I ran it four weeks, then stopped to update firmware, then ran continuous operation for exactly 365*5 days before it apparently ran out of cesium couple months ago. So probably six years total (but I can only be certain of last 5.1 years).

When designing a synchroniser it is useful to have a quntitative model of the metastability characteristics of the devices used so that a reasonably accurate estimate of its output metastability rate can be calculated. Bruce

I did not perform a tolerance analysis on this measurement & can only estimate the error at +/- 40mV/Rad. The 90 deg offset of the SYPD-2 was measured at < 500uV using +7dBm input power to both RF & LO ports.

Normal estimates are in the 10K rad range. It all depends on just what nasty impurities there are in the lattice.

The better we know the receiver position (x, y, z) we can reduce the error in estimating the b term. Since the above equations have 4 unknowns, you need 4 birds to solve it. While these equations are non-linear, there is a linear solution to the above problem lurking in there. A nice little exercise with paper and pen. Cheers, Magnus

. :-) If you are interested, the made up boards will cost GBP57.50 plus shipping, and the bare boards will be GBP12.50 each plus shipping (originally estimated at GBP14.50). If I gave anyone a lower figure than GBP12.50 for bare boards, my apologies I forgot to allow for tooling costs.
