History
I have worked with time and frequency equipment for over 40 years at Vandenberg Air Force base. I am a contractor working with satellite commanding and telemetry. On the side I specialize in the repair and calibration of Cesium, Rubidium, and Quartz frequency standards. The first standard I worked on was a Manson RD-180 Quartz standard. I then worked on various quartz standards. My first Rubidium was a Varian 4700. (A real boat anchor!) Heavy but neat. Then followed Varian R20 units, HP5065A units, All the different Efratom units, many FE units and SRS PRS10 units. Cesiums were HP5062C (I've allways liked the 5062C design!), 5071A, 5060A, 5061A, 5061B, FTS 4050, 4060, 5000, 5030, 4010, and some FE units. I have been baby-sitting a friends EFOS2 Hydrogen Maser and utilizing it to test the short term stability of numerous quartz oscillators, and to analyze the design features of the HP 5065A. The 5065A is my favorite to work on. I also enjoy making custom modifications and designs. |

What I sell and how I test
The frequency standards I sell are all tested for over 100+ hours to verify proper operation and stability. I use an HP 5071A, a hydrogen Maser, a GPS system, and a customized SR620 counter system using an NBS DMTD unit and computer to verify my accuracy. An example items I sometimes have for sale: -HP10544 Quartz modules -HP10811 Quartz modules -HP5062C, 5061A 5061B Cesium standards -HP5065A Rubidium standards -FTS 1000A, 2000, 1200 Quartz modules -Efratom FRSC, FRK, M100 rubidium modules -SRS PRS10 rubidium modules. | |
