Hi It’s almost enough to get one to sign up for a course at the local college every decade or so, just to be able to legitimately get student copies of some of this stuff. === That said, a lot of these companies do quite a bit to support education. I’ve seen them toss out a *lot* of licens

OK I can see I am in the same boat I always have been old HP gear as mentioned above. Still I will install and tinker for some fun. I mean the factthat you can interface to arduinos for control of bits and such could be useful. Will have to see. Regards Paul WB8TSL On Sat, Jun 20, 2015 at 6:03 PM,

Re: [time-nuts] potential source for cheap copy of labview

Hi Dave: When I was working with LV you could run the program on a Mac, Windows or Unix without any changes. It's my understanding that's still true. Note the instruments that accept SCPI commands are pretty much interchangeable. It's the "R2D2" commands that are model number specific. The

Re: [time-nuts] potential source for cheap copy of labview

Well this looks interesting. You can download what appears to be the same bundle for a free 45 day trial. Doing that at the moment. Then there is the NI-Visa download and it has gpib. Not sure what much of this means in reality. What drivers do they have to get to the old clasical fat GPIB used on

Here's the National Instruments web page about the "Maker" (I also hate that term) version. It is the same as the $2999 Full version with the addition of the $2119 Control and Simula

Re: [time-nuts] potential source for cheap copy of labview

They provide an evaluation version that lasts for 45 days, and if you like it you can buy the 'LabView Home Bundle' for $49. Apparently the home version is Windows-only, which I sadly didn't realise till after a 1.4GB download. I can't complain too much, though, given the price and the feature set

Hi Bob: That's exactly the question I had yesterday. I was a certified LabView programmer and yesterday was thinking about having a local computer store making me a WIN 3.1 computer so I could run my old LV code and write some new code. I may still do that, but for now I have the $50 LV Home

[time-nuts] SR-620 noise floor question

Dear Time-Nuts, I played around with my SR-620 counter and TimeLab and got strange ADEV curves, so I started to investigate a bit. The SR-620 is equipped with Option 1, the high performance Wenzel OCXO - specified with 5E-12 at tau = 1s. I tried to evaluate the counters noisefloor. I fed 10 M
