Re: [time-nuts] Warning if buying from directly from Agilent via eBay with Paypal.
I would strongly suggest that you consider buying Agilent Certi-Prime items not through EBay but through one of the distributors that they now sell much of their equipment through. I have dealt with Electro-Rent on this kind of equipment and had much better response and less hassle if there are problems. I don't know if E-R operates in the UK, but I suspect that there is an equivalent there. Sorry to hear you had trouble with the FieldFox as I am considering one myself.

Re: [time-nuts] Z3805 two frequency maxima
Hi That's what you get if you have sub harmonic energy in the output of your OCXO. I'd bet you a warm glass of beer that you have a 5 MHz / doubled to 10 MHz MTI OCXO in your Z3805. If you have a lot of time on your hands, you can calculate the likely level of the energy from the amount of jitter (spacing between the two peaks) you get.

Re: [time-nuts] getting a grip on 10811 drift (trying to read my instruments)
The picture, if attached, did not come through. Probably it was stripped off by the mailing list software. I did located what I believe you were speaking of. A small white donut placed in the circuit board which was an attachment point for the trimmer and a smaller fixed capacitor and the blue wire going to the crystal. Mine looked ok but maybe a bit dry compared to two other such fixtures on the middle board. So I touched it up with more solder on both sides. I also touched up the other end of the small fixed capacitor. I have the oscillator running and so far it seems happier. It warmed up faster, the trimmer adjustment seems more sure-footed.

The discounts on eBay (48% was agreed, prior to my adding a couple of more options), were much better than on the Agilent web site (35%). I don't know how much I would have got off of other dealers, but quotes I've had on other equipment have been quite small discounts (5%) from the Agilent web site. I have dealt with Electro-Rent on this kind of equipment and had much better response and less hassle if there are problems. I don't know if E-R operates in the UK, but I suspect that there is an equivalent there. Microlease is one such place in the UK. A friend of mine has suggested to me Livingston Hire, which mainly hire kit, buy my friend said Cellnet used to get a better discount from Livingsone than they did from Agilent. I've not tried contacting them yet. Sorry to hear you had trouble with the FieldFox as I am considering one myself. In the 2-3 weeks I had the FieldFox, I discovered a large number of firmware bugs. Agilent agreed several were bugs, and others were submitted as requests for enhancements. Some of the bugs were so obvious - like the firmware version mine was shipped with, would not interface to a computer. That was not just a newly discovered bug, but had been documented in the release notes and was the stable release for some time. That was until Agilent discovered it had a bug which could give the wrong results under some conditions, so it was pulled from the Agilent web site. If you do get a FieldFox, the QuickCal is a nice option to have. It is not as accurate as a mechanical calibration kit, but still good, and very convenient. If the highest accuracy is not required, you just leave the cable open with an N,APC-7 or whatever connector you specify, and it does the cal from just the open connector. For better performance with a DUT which reflects very little, then a load is needed too, but that does not need to be a good quality load. For the very best performance, you need a mecanical cal kit. I paid for all the options, which with hindsight was not such a clever idea. If you do buy a FieldFox, I think I'd at least try to get a trial of the options for a few weeks - they can be time-limited. There are no hardware options - the hardware is there, but it needs to be enabled by software. I think several of the options are really aimed at technicians, who might have limited knowledge, as they just present information in a different way to which one can read off the S-parameters. For example, the vector-voltmeter, which is not a high impedance voltmeter as you might assume, but just gives a big display of the loss and electrical length of a bit of cable. Great big numbers, very easy to read, but actually showing you nothing you can't simly read off the S paramters. There's an option for antennas (I forget what it is called) which gives a time-domain response, to find faults in cables. That really tells you nothing the TDR option does not tell you. But the TDR option is a lot more capable (and a lot more expensive). But it is a bit pointless having both.

Re: [time-nuts] Z3805 two frequency maxima
Hi 60 db isn't to bad a number. More or less: 100 ns - 100 ps is 1000:1. 20 log of that is 60 db. 100 ps to 60 ps is about 4.4 db. That would sum up to -64.4 dbc. The main gotcha is that you *might* also have some 15 MHz (and higher) energy in the signal as well. Also phase gets into the calculation. Still, pretty close.

Re: [time-nuts] Warning if buying from directly from Agilent via eBay with Paypal.
That works just fine. I have two Paypal accounts, one tied to my regular bank account which I use for purchases, and another tied to a small account at a local bank (where I keep almost nothing) which I use for selling. As soon as money goes into that account I use an ATM to withdraw cash, which makes it harder for Paypal to track even if that bank gave them records as there is no direct link to my other account. I did add a credit card to my main Paypal account but I find that useful at times. Peter On 11/17/2012 5:37 PM, J. Forster wrote: Perhaps.

However, this is over the limit I can pay via Paypal, which is $10,000.

That's what concerns me - especially if the $1 goes through, but I can't get the rest to you. It could be a bit tricky.

I was initiallly a bit worried about wiring the money, but I'd satisfied myself he was a legit dealer when I spoke to a test equipment dealer in the UK, who confirmed the price I got was very good, and the dealer was reputable. So I wired the money, and saved myself a few percent. That transaction was relatively painless.

Re: [time-nuts] Warning if buying from directly from Agilent via eBay with Paypal. Shipping delays
I have been waiting for two N1922A sensors for a couple months now from Agilentused the new eBay site. They have already offered a substantial discount on my next purchase. And their prices were already very good. The only concern is the delay has put the transaction beyond the point the eBay or PayPal will officially help out if there is a problem. That said I am sure that Agilent will resolve any problem to my satisfaction. Agilent used explained they are having some delays as they add products to the new system that should be resolved soon. My only concern is that because of the delay they do not rush when refurbishing the sensors. I would hate to start the wait all over again. I hope they work the delays out, it seems to be the cheapest source for many current Agilent products. For the others that have had problems, I would explain to Agilent that you have acted in good faith and expect a full refund or a product that performs as new. Agilent may not be aware that PayPal and eBay did not return fees because of their delays.

Re: [time-nuts] Z3805 two frequency maxima
Hi A little more detail: What's going on is more clear if you trigger a scope on the positive edge of the 5 MHz and look at the 10 MHz. With an ideal multiplier, both the positive and negative edges of the 5 MHz should line up exactly with a positive edge of the 10 MHz. In reality, negative edge (the one not triggered) does not quite line up. It's a bit ahead (or behind) the ideal location. Since it's a small angle, the delta in phase and delta in amplitude both follow the same basic law. Bob On Nov 17, 2012, at 9:36 PM, Bob Camp li...@rtty.us wrote: Hi Just good old Fourier series.

[time-nuts] Wanted - AN/URQ-10 manual
Can't help you with the manual but I just wanted to say that the 1051 was one of my favorites. Loved the PLLs. I worked on an upgrade for Stewart Warner back in the early 80s. As part of a prototype I put two Z-80 systems in the space between the front panel and the main gear. Part of its purpose was to interface to the 1553 bus. I also implemented a DDS in TTL for fine tuning. I still like tube front ends for mil radios for ruggedness. But you can't sell it because of wear out issues. The Navy didn't buy in to the prototype. Collins beat us. The code for the processors was written in Forth. The Navy code inspector said it was some of the best written code he had seen in several years. We also could complete a design cycle - including code - in a month. The Collins boys had a team 10X as large as ours (we had 3). And it took them 6 months to complete a design cycle using C. I was project manager and lead engineer. I was mostly hardware but I did some software and rode heard on the coders. Forth was my idea. I also put a Z-80 inside the companion 1KW transmitter. The RF inside the transmitter was a few volts per inch. I used a sealed box and a lot of feed through filters. It worked the first time. I also worked with the gear in Navy ETA school. And went on to become a Nuke so I didn't see that radio gear again until about 15 years later.

Re: [time-nuts] Warning if buying from directly from Agilent via eBay with Paypal.
-Original Message- From: David Kirkby [] This is some of the communication between me and Agilent on eBay. I think it is clear Agilent wanted to use Paypal, and I did not. It was Agilent who said I should split the payment into two - one of $10,000 and the other of $7,736 [] Dave == $17,736 seems a high price when the typical configured is US $13,200 (GBP 8308): http://www.home.agilent.com/en/pd-1760161-pn-N9923A/fieldfox-handheld-rf-vector-network-analyzer-4-6-ghz?cc=GBlc=eng I have also experienced currency problems - when the US $ changed between me quoting and him paying. Accused me of all sorts when it was simply that there were currency fluctuations and my quote was in GBP. He ended up paying more dollars, and didn't like it at all!
