Re: [time-nuts] Lucent 40 dB Antenna
Hi Joe, 40dB is not needed when you have a short (10m) /good antenna cable. Then 26dB will be plenty fine. Howver going to 20 or 30+ meters using standard RG58 will be a problem with 26dB. Ofcause what matters is the attenuation at L1 with your cable. Better cable can be longer... You do not need an spectrum/network analyzer. Take a your antenna and receiver to a good site, if you installation site might be marginal. Your C/N0 (snr) should be around or above 50dBHz for high elevation satellites. Then compare the C/N0 values for you antenna at your workshop, to see how much worse than perfect that site is. If using a Tbolt remember to change from Trimble AMU into dBHz. Note that LNA dB amplification not generally translate direcly into dB carrier to noise ratio. -- Björn PS I got a small batch of HP timing antennas new in box for around $25 a piece some years ago... :-) DS Mine arrived in the same manner. It works but I can't tell any real difference between it and my 26 dB antenna, switching between them when mounted on the corner of the roof of my workshop.

Re: [time-nuts] Lucent 40 dB Antenna
Bjorn, My setup is a Lucent 26 dB antenna on a bracket on the edge of the roof at the corner of my workshop feeding about 20 feet of 9913 coax (7.5 dB attenuation per 100 feet @ 2.4 GHz) to a 58536A four way splitter that feeds a Z3816A, Z3805A, TBolt, with a 'spare' for playing with. The splitter uses about 2 feet of 9913 to the Z3816A and the Z3805A and the TBolt is fed with about 6 feet of RG58 with BNC connectors and adapters for BNC to F and BNC to N. With SatStat and a Z3816A, C/N is typically 30 to 50. With TBoltMon or Lady Heather and a TBolt, dBc also typically 30 to 50. I didn't see much difference on either with switching antennas but I suspect I have a fair amount of signal to start with (Lat of 30 degrees but under trees).

Re: [time-nuts] Looking for CA3130E IC...
CA3130EZ is the lead-free version of the part. Looks like good stock (both Newark and Avnet have thousands on the shelf), and should be usable unless you're sending it into space or something. If so, it appears that Rochester Electronics http://www.rocelec.com has stock on the shelf. They are authorized distributors and manufacturers of obsolete semiconductors, and oftentimes the last resort for old components. If necessary, they can package from die that they have in stock, or even reverse engineer old designs. Of course, that's very pricey, but if you're a government and need to maintain some 20 year old piece of critical equipment, they may be one of the few avenues to getting something working again. --Glen Quoting Bob Smither smit...@c-c-i.com: On 04/13/2012 05:45 PM, Michael Blazer wrote: Findchips was my first choice as well.

Re: [time-nuts] Lucent 40 dB Antenna
I think I got lucky. Despite the almost nonexistent packing, my antenna looks like reasonable wear and tear for a used item and didn't suffer much from shipping, and it passed an operational check on the bench today. Setup was an 8566B SA as receiver, bias tee on the input, 5vdc to the antenna, and about 10 inches of RG8 to the Lucent antenna, which was hand held. The source was a GS-100 GPS simulator into a log periodic that was only designed for 400 - 1000MHz but it was what I had in reach. Distance between the source antenna and the DUT was about 12. A far from optimal, cobbled together setup but it was quick and easy. With the GS-100 output connected to the SA through 18 of RG8, the signal level was set to -70 dbm for a reference. When the aforementioned crude lash up was put in place with the antenna powered up, the signal level on the SA increased 10-12 db. This was far from scientific but it gives me enough confidence that at next opportunity I can take it up into the attic for further testing.

[time-nuts] Opinion Of Attached - Possible HPSDR GPSDO 'Engine'
Are the Jupiter GPS engines still available? Don't know but if I was doing it today I would use the ublox timing receiver or the Motorola timing equivalent and a good sc-cut docxo and build it. Of course I don't have the know-how but it would be an incredible open source build that I would buy from tapr if it was standalone (didn't have to plug into the back-plane). I would presume the sub 1000 s adev is worse than 1x10-10 on that part so the miller approach seems cheaper and more stable.

Especially short tem. http://www.jrmiller.demon.co.uk/projects/ministd/manual.pdf The short term performance of a GPSDO is defined by the short term performance of the OCXO. I think the proposed device that was quoted at $300 used a TXCO, not an OCXO. One could also use a double oven XO (DOCXO) One way to get good performance and low cost is to make the system modular. It breaks nicely into three parts 1) The GPS 2) A voltage controlled oscillator which could be a double oven OX or the cheaper TXCO or whatever 3) the GPSDO controller. As shown on the PDF file above these can be very simple. All GPS and most oscillators have about the same interface so an end user could choose his parts based on budget. If you'd build a stand alone controller that would accept timing pluses from a GPS from 1Hz to 1KHz and would output a voltage to control an oscillator you'd have a pretty popular device. The problem is the competition. It is hard to build anything that is better than the Thunderbolt without spending more for parts than the price of a Thunderbolt.

Re: [time-nuts] Opinion Of Attached - Possible HPSDR GPSDO 'Engine'
I recently had a chance to look at the GPSTCXO. I was quite impressed. It's performance is a lot better than any bare GPS receiver, but maybe not as good as some GPSDOs. Here are some measurements that I made on the 1 PPS of the GPSTCXO and other GPSDOs: GPSTCXO Std. Dev. 400 ps. min-max range 4 ns. Tbolt 500 ps. . ~ 4 ns. Z3801A ... 300 ps. . ~ 2 ns. Z3817A ... 100 ps. . 1 ns. These measurements were 1000 pulses or more measured with an HP 5372A or 5370B for the Z3817A. The Z3817A requires an external 1 PPS source to lock to. I used a Navsync CW12-wi. Over longer periods of time typical GPS wander is present in all units. I measured the 10 MHz output of the GPSTCXO with the Histogram Time Interval function of my 5372A. Out of 200 million cycles, every one had a period of either 100.0 or 100.2 ns. There wasn't even one outlier. I have OCXOs that aren't nearly that good. A few random points to remember about the GPSTCXO: - There's no way to set the time zone offset - fixed at UTC. - There's no way to set the elevation mask - fixed at 10 degrees. - The Allen Deviation matched the graph in the manual which is available at the Jackson Labs site. - On the evaluation board, the 1 PPS is wired to the DCD lead on the USB-emulated serial port. - I can confirm that, as mentioned in the manual, performance improves substantially when you shield the unit from temperature fluctuations. - If you use Z38XX to communicate with the GPSTCXO be sure to disable serial echo as described in the manual. The GPSTCXO _really_ doesn't like serial echo. It can cause the unit to reboot. The GPSTCXO stands between a bare GPS timing receiver and a typical GPSDO. It's performance is closer to a GPSDO than to a GPS receiver, but it's price is closer to the bare receiver than to the price of a new GPSDO. It should be useful in many situations. I have no relationship to Jackson Labs. They did make a GPSTCXO available to me for this testing.
