USED. IN EXCELLENT CONDITION. There are some scratches and minor dents on shell.But the PCB is in good condition and the unit works fine. This is a programmable clock from 1Hz to 20MHz. With the low phase noise of this clock. It is the best choice to create a super clock standard using FE-5680A. The supply of this clock use 15Vdc and current about 2A. After warm up for 10 minutes, the current will drop to about 0.75A. Thus the continue power consumption is about 12W which is quite a lot and thus the metal body should be attached to a heat sink or metal chassis for cooling. The FE-5680A features: programmable clock from 1Hz to 20MHz.

Lucent RFG Rubidium Frequency Standard- Calibrated- HAM This rubidium standard was manufactured by Lucent Technologies using the highly regarded Efratom FRS rubidium oscillator. It was originally rack mounted and received its power from. And delivered its output to, the larger system. This unit now has its own power supply and lock indicator, and is ready to use as a stand-alone unit. Photo 4 of the interior shows the added power supply and(at the lower edge) the 10 MHz output filter that ensures a clean sine wave output with no DC offset. Output is 3 volts P-P into an open circuit, or half that into a 50 ohm load as seen in photo 2. If required, a 15 MHz signal is available behind the small panel at the rear. This standard is in excellent working condition and achieves rubidium lock within 2 minutes of receiving power. Although the lock ... moreindicator will not light until the oven temperature has stabilized(less than 15 minutes) Accuracy is extremely good almost immediately, with very high stability achieved in less than an hour from turn-on. It was very recently calibrated against a laboratory standard which is phase-locked to the 10 MHz signals of the GPS satellite system cesium standards, and exceeded the original Efratom factory guaranteed accuracy at the time of calibration. It ships with the Efratom FRS 80-page manual on CD in PDF format. If you'd like a very accurate frequency standard. You'd do well with this one!

Stanford Research PRS10 10Mhz Rubidium Frequency Standard with Manual on CD Tested. Works The PRS10 is a ultra-low noise 10 MHz frequency standard which disciplines an SC-cut ovenized oscillator to a hyperfine transition in the ground state of rubidium. The PRS10 was designed to fill a variety of communication. Synchronization, and instrumentation requirements. The phase noise of the 10 MHz output is low enough to be used as the reference source for cellular synthesizers. The unit’s short-term stability and low environmental coefficients make it an ideal component in network synchronization systems. Also, the low aging rate makes it an excellent choice as a timebase for precision frequency measurements. The unit is compatible in fit, form, and function to the Efratom FRS frequency standards, with improvements in features and performance. ... moreThe PRS10 allows closed case diagnostics and calibration via an RS-232 interface, its digital synchronous detection and filtering eliminate spurs on the 10 MHz output, and the PRS10 has 1000x less phase noise than the Efratom unit(130 dBc vs. 90 dBc at 10 Hz) The PRS10 can time-tag an external 1pps input with very high resolution. These values may be reported back via RS-232 and/or used to phase lock the unit to an external reference(such as GPS) with a time-constant of several hours. This feature can provide Stratum 1 performance at a very low cost. In addition to reading time-tag results, the RS-232 interface allows the user to set the Any questions please ask before bidding What you see is what you get Your bid is a contract.

Used but in a mint condition. Quartzlock GPS disciplined RUBIDIUM Time and Frequency Standard, Pulled out of working environment. It comes with a manual. Please see the pictures for details. Unlike most low cost GPS receivers the Quartzlock model A8 series Frequency Standard Receivers are able to perform extremely high resolution carrier phase measurements for each satellite being tracked. This yields a frequency resolution which is better than“code-only” detection by a factor of 10. 000. By performing carrier smoothed high resolution code evaluation the model A8 is able to make range(or time) measurements of far superior precision to non-carrier. Code only detection receivers. This enables the model A8 to detect almost instantaneously any local oscillator frequency excursions and makes fast corrections such that. Even with a low cost crystal, ... morethe short term stability is well controlled. The model A8 is therefore unique in its price range and yields performance equal to that of less affordable multi-channel receivers. All satellites in view are tracked and fast time frequency averaging is performed which minimises errors due to any single satellite. All satellites URAs(User Range Accuracies) are taken into account in the course of the averaging process. Further. Significant errors can be eleiminated from the averaging process by the use of special plausibility checks and the ability of the receiver to assume that it is stationary with respect to the earth having fixed its position to an accuracy of better than ±2m(which it may do automatically given sufficient time.

Auction consisting of: 1- Symmetricom SA.22C 10MHz Precision Rubidium Reference Oscillator 1- 2x9 2mm surface mount connector 6- Flathead metric mounting screws Only what is listed above and/or shown in the pictures below are included in this auction. This auction is for a Symmetricom model SA.22c rubidium oscillator. This oscillator is a pull from a telecom application(output originally at 15MHz) However, we have switched the output to 10MHz(see dump below) and turned on the 1pps. The power-up header indicates that the 1pps is off, however, it has been changed to ON and defaults to ON at power-up. The unit is in a very small package and uses both +15V and +5V for the supplies. Interface is a 2x9(18-pin) ... more2mm connector. Output is an ACMOS signal. Unit also has analog voltage frequency control(currently defaults to OFF, but can be changed) and digital step control(2x10E-12 resolution) via the serial interface. Serial interface is also CMOS/TTL interface levels(you need a converter to get to RS-232C) There is also a lock signal output as well. The output frequency can actually be changed to any value of 60MHz/2N where N=1 to 65536. The firmware in this unit does NOT have the 1pps input discipline capability(6.02c is in this unit, 1pps discipline starts with 6.05c) However, there is an internal time interval counter(TIC) that can be accessed via the'j' command that does return a value of the difference between the 1pps input and the rubidium oscillator output(which is kind of neat) For more detailed information we have provided this link to the website. Here is the startup header from the serial port and the output of the'w' command(from a typical unit) SA22C by Symmetricom. Inc.

Efratom SLCR-101 Rubidium Frequency Standard- Calibrated- HAM Here's a very nice. Accurate rubidium 10 MHz frequency standard for your lab or"shack. The Efratom SCLR-101 is a re-packaged version of the original Datum/Symmetricom LPRO-101, but is lower in in height. They are operationally identical. Specifications for the LPRO unit apply equally to the Efratom SLCR. The Symmetricom data sheet is shown in photo 4. This unit has been recently calibrated against a laboratory standard kept phase-locked to the GPS system cesium standards. And is guaranteed to meet or exceed its original factory accuracy specification. The output is a nice, clean sine wave of approximately 2.5 Volts P-P(photo 2) and about half that into a 50 Ohm load. Photo 3 shows its measured accuracy on my HP 5334B counter. Actual accuracy is much greater than the resolution ... moreof the counter can display. Measured frequency offset from the standard was +0.76E-11 at the time of calibration, measured over a 6 hour period after an initial 6 hour warm up. Lamp voltage is 8.7 Volts, an almost new value, and this standard has many years of useful life left. The Efratom SLRC-101 runs on a single 24 Volt DC power supply with a start-up current draw of just under 1.5 Amps. After warm-up. Operating current drops to under 0.5 Amps. Included documentation(in PDF format on CD) is the Symmetricom Data Sheet and the Datum User Guide, plus a schematic diagram for constructing a portable standard with multiple outputs that can be run from a car battery. The other instruments and BNC cable shown are not included. You will also need to supply your own connector. I purchased this unit to build my own frequency standard. In the meantime. However, I've acquired several commercial units and have no need to"roll my own. Nor do I have the time, no matter how fun it might be. If you'd like a good rubidium standard that you can be sure is operating properly and accurately. You'd surely be pleased with this one! Very carefully packed and shipped via USPS
