If you're in the GPIB hardware business, you cannot release an API for your hardware that supports the ibnotify() function without licensing this patent. Needless to say, LabVIEW requires ibnotify(). Agilent does have an NI488.2-compatible API layer for their hardware, and ICS has been shipping NI488.2-compatible hardware for a long time now. Agilent may have been able to license the patent from NI; in any event NI wouldn't be crazy enough to start a patent war with them. But I have no idea how ICS has handled the issue, and I'm not aware of anyone else who has tried. If you live in the US, you might consider writing to your legislators to try to educate them on the economic effects of software patents. You can also contribute your thoughts on post-'Bilski' patentability to the USPTO here: http://www.uspto.gov/news/pr/2010/10_35.jsp . -- john, KE5FX ___ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.

Stanley, Would you be willing to do another "group buy"? I'll send you enough $ for 10 of them via PayPal before you buy and I know others are already willing to buy more. I just can't logistically do a group buy myself right now but would be willing to help pay for your time and efforts. I know what they are in quantities of 50. I'll pay $2 each.

Re: [time-nuts] Z38xx and z3805
Hi Bob, I have a Z3801A and I am not sure whether the SCIP commands are the same as for the Z3805A. There must be some differences related to the channel numbers and serial post configuration at least I would expect. I think the following apply. You need to not only be able to provide a position, as was suggested, or from a survey, but to also prevent site survey from starting up at power on. Survey at start is default, at least on the Z3801A, and from what you say, I suspect your box does the same. If a position is specified, or the survey completes OK, the unit should go to position hold mode automatically. To check. :GPS:POSition:HOLD:STATe? To specify what startup mode you want :GPS:POSition:SURVey:STATe:POWerup ON or OFFON forces a survey. to check :GPS:POSition:SURVey:STATe:POWerup? If it is turned off the receiver will use the last valid position it has. This might be the default , (Korea) if the eprom is shot. hope that helps, Mike Le 02/08/2010 00:42, Bob Camp a écrit : GPS:POS N,DD,MM,SS,W,DD,MM,SS,ALT > ___ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.

Re: [time-nuts] Prologix GPIB controllers
Bob, Thanks to you and all the other people on this wonderful list (on and off list) who have recommended this product... done. Ordered with "Next Day Shipping". Got a lab coat too (couldn't pass it up... the one's I have at work are "disposable" as getting someone to clean them is near impossible or actually too expensive as it's a bio-hazard) as well as a bunch of other stuff that was just sitting in my SparkFun cart. Oh well... fantastic excuse for placing the order and I'm sure my wife will LOVE me wearing a lab coat around the house. ;) Grabbed a few more (okay... a dozen) logic level converters too while I was at it. It seems these days... everything I'm working with is either 1.8v (Gumsix Overo), 3.3v (Arduino and Propeller), or 5v (everything else) and nothing likes to talk to each other without a logic level converter. Anyway, I'm looking forward to being able to getting the HP-B/GP-IB data out of the HP 5335A (and other equipment to come) and being able to log it and do something useful (unlike wearing the lab coat around). hehe Thank you all... I'm on the right path (I think) with measuring "time" but it seems to lead to insanity.

I do not have a 5335A, but... I use a ProLogix USB-GPIB adapter on a HP5370. I am not doing anything fancy, no real controlling. I set the GPIB on the 5370B to talk, then use John Miles GPIB Configuration program for the adapter.

After running the configuration program, you close it, then bring up a terminal emulator - HyperTerminal built into Windows - and capture the data.

I have a couple notebooks with PCMCIA (AKA PC Card) slots. A few years back I got an NI card on eBay. Probably harder to find than a PCI card and possibly more expensive, but it is one more option that should be compatible with all the software. Doesn't need a full sized PC too. It is one more option that wasn't mentioned, but slots are harder to find on newer notebooks. On 8/1/2010 5:55 PM, Robert Darlington wrote: I have the Ethernet version.

Re: [time-nuts] HP 5335A and HP-IB (GP-IB)
I have the Ethernet version. They're nice for quick and dirty stuff and the USB / Ethernet versions can be used on laptops (Ethernet can be used on any computer that can telnet across the wire). You get to write your own software to use them or use EZGPIB (and write your own software). Using a "real" NI GPIB interface means it works with everything out there, including EZGPIB but you're greatly limited on hardware platforms. You're stuck using a computer with a PCI bus unless you want to fork over the cash for the NI USB or Ethernet interfaces for lots of money. I tend to use my PCI-GPIB card and it was under $100 delivered from eBay. -Bob On Sun, Aug 1, 2010 at 5:18 PM, Heathkid wrote: > I just purchased a HP 5335A and would like to know the group's opinion on > the following: > http://www.sparkfun.com/commerce/product_info.php?products_id=549 > > 73 Brice KA8MAV > > ___ > time-nuts mailing list -- time-nuts@febo.com > To unsubscribe, go to > https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts > and follow the instructions there. > ___ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.

Hi The good old Iotech RS-232 to 488 converters will drive a counter 5335 counter just fine. They are < 1/3 the price used. Not much to running one.

Re: [time-nuts] HP 5335A and HP-IB (GP-IB)
Depends on what he wants to do. If he wants to write his own apps for the counter (or use mine) the Prologix controller will work fine. You talk to it with generic COM port code rather than a proprietary API. If he wants to run existing commercial software like Labview he is likely better off buying a used National Instruments adapter on eBay, though. It will not necessarily be any cheaper than a new Prologix adapter... probably close to the same price in fact, unless he makes the mistake of buying an ancient ISA-bus or RS-232 adapter. -- john, KE5FX > -Original Message- > From: time-nuts-boun...@febo.com [mailto:time-nuts-boun...@febo.com]on > Behalf Of Bob Camp > Sent: Sunday, August 01, 2010 5:36 PM > To: Discussion of precise time and frequency measurement > Subject: Re: [time-nuts] HP 5335A and HP-IB (GP-IB) > > > Hi > > I think I'd haunt the e-place for a much cheaper alternative. > > Bob > > > On Aug 1, 2010, at 8:18 PM, Heathkid wrote: > > > I just purchased a HP 5335A and would like to know the group's > opinion on the following: > > http://www.sparkfun.com/commerce/product_info.php?products_id=549 > > > > 73 Brice KA8MAV > > > > ___ > > time-nuts mailing list -- time-nuts@febo.com > > To unsubscribe, go to > https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts > > and follow the instructions there. > > > > ___ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.

Re: [time-nuts] GR 1115B
Hi It's an early Warner resonator so stress is an issue. It is drifting in the right direction. I am also worried that the tuning coil may be tough to replace.
