Lucent RFTG GPS Disciplined Frequency Standard(GPSDO) HAM This is the frequency disciplining section of a Lucent RFTG frequency standard. It's the second(and last) of these units that I have available. The RFTG consists of both an ovenized crystal oscillator(OXCO) which is disciplined by a GPS receiver and associated circuitry. And a separate rubidium oscillator, which is also disciplined by control from the OXCO. The system is redundant, and both the OXCO and the rubidium oscillator sections are capable of being operated independently. From the exterior they both look alike, but only the OXCO has independent GPS capability. I prefer the OXCO as a standard over the rubidium unit for two reasons: 1) The stand-alone rubidium unit must be periodically calibrated. The OXCO is self-calibrating by locking to the cesium beam standards of the ... moreGPS system. 2) The rubidium unit will eventually"wear out" due to gradual failure of the excitation lamp. The OXCO will last indefinitely. Even if left on continuously- which is the preferred mode of operation. This standard has been fitted with its own indicator and power supply. And is extremely simple to use. There are no switches or controls, just a red/green LED to show GPS lock status and a 10 MHz output port on the front. An antenna connection and a power input are on the rear. There is no on/off switch, as the unit is intended to operate continuously for maximum accuracy. The GPS receiver is shown at the top in the fourth photo, attached to the removable bottom of the standard. This receiver and antenna connection are not present in the rubidium version. The output impedance is a standard 50 ohms. With just over 4 volts of clean sine wave output into an open circuit as shown in the second photo. The output is a bit less when terminated in its 50 ohm characteristic impedance. A new power supply and"starter" antenna are included. However, the receiver should have a standard mast-mounted antenna for best operation. They are available at modest cost here

TrueTime/Symmetricom XL-AK GPS Disciplined Oscillator(GPSDO) This is the TrueTime aka Symmetricom model XL-AK 600-101-1 receiver and GPS disciplined frequency& time standard. The instrument contains the optional 86-690 Output Configuration“L” Board which allows the user to select the analog or digital signals that will appear at five rear panel BNCs labeled J1 through J5. Signal selection is made by the installation of jumpers. Outputs include 10 MHz and 1 PPS signals. Analog output formats are: IRIG B AM IRIG B amplitude modulated. Analog signal amplitude is 1 V rms into 50 ohms. Digital output formats are: IRIG B 001. IRIG H 001, and IRIG E 001- These are the DC Shift formats of IRIG B, H, and E time code. ALARM- This output level is asserted by various programmable alarm conditions such as timing error during loss of lock or antenna ... moreshorts. A Programmable Pulse Output allows the generation of a precisely synchronized trigger pulses at an arbitrary time and with arbitrary pulsewidth in integer multiples of 1 ms. Pulse rates are: 1 PPS, 1 KPPS, 10 KPPS, 1 MPPS, 10 MPPS. These pulse rate outputs have a 50 percent duty cycle with their rising edge“on-time. Digital output amplitude is +2.5 Vdc into 50 ohms(+/24 ma) 0 to +5 Vdc Open Circuit) The Symmetricom data sheet is included in the attached photos. The instrument also has the optional up-converter board installed piggy-back on the receiver. It receives its power from the receiver and has two SMB connectors to accept an input signal and deliver the up-converted signal back to the receiver. This board may be un-plugged and removed. However. It appears that if this is done, some jumper settings on the receiver board will need to be changed for the receiver to work properly. As I do not have a proper antenna to supply a down-converted signal, nor the information needed to operate without the up-converter board, I am unable to receive any satellite signals to prove its operation. Therefore this instrument is sold as-is for parts or repair. It ships with
RDR ELECTRONICS WILL ONLY SHIP TO U.S. ADDRESSES. FOREIGN BIDDERS WILL BE APPROVED TO BID ONLY AFTER PROVIDING A U.S. SHIPPING ADDRESS! Auction consisting of: 1- Nortel NTGS50AA GPSTM GPS Timing Module 1- New-In-Box Alcatel/Lucent CC-849143987(manufactured by PCTel- GPS-TMG-26-MCN) GPS antenna 2- SMB pigtails(for GPS antenna and 10MHz) Only what is listed above and/or shown in the pictures below are included in this auction. This auction is for a cell site GPS timing reference module that has a Trimble GPSDO built into it and can be controlled from the Lady Heather software program. This unit runs from 36 to 72 volts DC(positive or negative. Both input lines are floating) The front panel has SMB connectors for the GPS antenna, 10MHz output, pulse per 2 sec output, and 9.8304 MHz output. There is also an RS-232 port for communication with ... moreyour control program. The backplane connector on the back of the unit has connections for power, 10MHz, pp2s, 9.8304MHz, serial port, and more(check out the document link- which has pinouts) This unit was built by Trimble and is a close cousin to their Thunderbolt GPS disciplined oscillator(GPSDO) and appears to be a newer version of the NTBW50AA module with smaller main board and separate daughter board for the lights and serial port(this unit would be much easier to re-package than the NTBW50AA) The GPS receiver is an 8-channel model(and appears to have much better input filtering than the NTBW50AA) The 10MHz oscillator in this unit is a Trimble p/n-34310-T2 unit. Removal of only two screws is needed to disassemble the unit, the board could be put in a 1U rack-mount box if desired(with power supply) The gain. Damping factor, and time constant of the control loop can be changed with the Lady Heather software on these units. So, you can fine tune them for best performance if desired. However, the changed values cannot be saved to the NTGS50AA EEprom so they are not persistent over a power cycle. The unit will accept input voltages from 36V to 72V DC( voltage

This receiver and antenna connection are not present in the rubidium version. Output is approximately 4 volts P-P of clean sine wave output into an open circuit as shown in the second photo. And half that value when terminated into a 50 ohm impedance. A new power supply and"starter" antenna are included. However, the receiver should have a standard mast-mounted antenna for best operation. They are available at modest cost here on eBay. About $30 will get you a new(5 volt) one if you shop. I'
This is an HP 58514A band pass filter(L1 1.5742 GHz) for a GPSDO. It will filter unwanted RF frequencies from interfering with the satellite GPS signal to your GPSDO. The factory seal is still intact. Not the prettiest looking piece but typical HP quality construction and performance.
This is a Brandywine GPS-4 which has the Brandywine High-Stability Oscillator option and 18-36 VDC input option. Includes an Acopian VA24MT210 24V linear PSU. You can look up the details on the Acopian website. It seems to have pretty good specs(and lists for $225 itself) Don't even ask how it compares to a T-Bolt or other GPSDO because I wouldn't be able to answer that. Includes a short serial cable adapter I made(it's kind of rinky-dink but it does the job) since hooking up a regular serial cable directly to the unit triggers a fault(or holds down in reset. It’s been a while so I’m not 100% sure) Brandywine in their infinite wisdom decided to shove a whole bunch of non-standard related functions on the DB-9 connector, so to prevent issues that's why I made the adapter with just the tx/rx/gnd wires. The extra SYNTH port is ... morefactory-set to 19.6608 MHz. I believe the PPS port is also configurable, check the manual for details. 10MHz is obviously a sine-wave. IRIG-B is AM(but I think it too can be configured) Uses a regular 5V GPS antenna with a BNC connector( not included) You can find the You can also Google and find the full PDF manual. But I will also include it on a CD. I’m not going to bore you with a ton of details about this piece of hardware. If you are looking at this auction then you*hopefully* already know what it is and what it is used for. If you have ANY questions feel free to contact me through eBay. I will try to respond with 24hrs. Guaranteed NON-DOA. Otherwise sold AS-IS. Buyer to pay actual shipping costs(calculated via eBay’s system) Local pickup is always welcome during regular business hours if you happen to live close by. I try to ship within a day or two of the auction ending. But PLEASE realize that I do not sell often on eBay and I have a day job so I can’t always drop everything to get an item shipped out the minute an auction ends. I will ONLY ship to a USA physical address. I will NOT ship international. Don't ask!
