new Rigol DSA 7.5GHz

[gmit77]

last week on italian road show some first test on the future Rigol 7.5GHz spectrum analyzer
stay tuned for more info

Here's hoping Rigol do another DS1052e style gamechanger and offer a 7.5ghz SA for around $1k

I passed on getting the Flir E4 so i am itching to spend money on some well priced test gear.

Maybe after a few years. The DS1052E was $800, ya know.

No problem, I'll settle for a big price drop on the DSA815-TG instead. I would buy one if it was 50% of it's current price.

[cyr]

Remember that even Rigol charges $4000 for their cheapest 3GHz analyzer, $1k for a brand new 7GHz model seems more than a little optimistic.

I'm sure it would be really popular if it was priced anywhere near the DSA815 level though, finally something affordable that covers the 2.4G and 5.8G bands...

I'd like to see them offer something similar to Tek's MDO3000 at a better price point. I think it's quite clever to use the scope ADC to do the RF frontend sampling, a 4GSa/s scope (about $300 in ADC if you use 4 x quad channel gigasample ADCs) could probably do 1.5GHz RF quite well.

[gmit77]

hello, DSA 7.5GHz won't be at 1000k
the DSA815 and DSA815-TG will stay at hte same price, just few new models with godd performance.

aww, dont say that, i want to live in hope

I wouldn't mind a 200Mhz spectrum analyser for $500 would be nce using the technique you mentioned.

Interleave 2 channels, add some additional front end attenuators and amplifiers and here you have it for 500$, plus you get all the algorithm options and a 2ch generator for let's say loop charachterization etc. And it is allready 14 bit, so a even better dynamic range if you apply dithering.

Why so why?
3GHz would be enough of a game changer, surely?

I do a lot of stuff in the 5.8ghz band for radio controlled plane video links. Building antennas, tracking down interference sources etc..  So for a SA to be useful to me it needs that band.
Also, there's a large number of new wireless technologies moving to the 5.8ghz band. It's fast becoming just as used as 2.4ghz.

Just last month i bought some wireless headphones which are dual band 2.4 and 5.8

Where are the decent Siglent/Owon/Hantek SA's?  The low cost 3GHz space seems ripe for competitors.

on http://www.rigolna.com the range is $6k5 to $9k5.

i'm still hopeful someone else with come out with something.

You can already get PC based analyzers that do up to 6ghz for $1.
Simply adding an internal embedded PC, screen and knobs should be possible for the top end of $2k

But they're not actually any good.

They're actually not too bad.

Just a few weeks back someone on the forum was saying how people are doing some pretty advanced stuff with the signal hound SA

This is cheap, under 6k$. But it looks like it is not designed for hobby market segment.

[videobruce]

There is almost no presence on YouTube or eBay for those Siglent units. In fact, there is very little anything in the US for these.
I would definitely avoid!

...some pretty advanced stuff with the signal hound SA

Must be a joke. Few months back when i checked the specs even did not say what input impedance it has, or Input Return Loss figure for that matter, neither harmonic distortion figure.

[theatrus]

I used one of the earlier model SignalHound and was not impressed.

For the cost it wasn't terrible (though the software was super flakey), but the current units are almost the same price as a fully functioning used HP unit (8595E or similar). As I'm not living in one of those IKEA "house in 200sq ft" places, I don't need the small size.

The old units had a dsPIC and an FT232H. I see there are now USB 3.0 units.

[videobruce]

Getting back OT,

The question is; Is the $1800 (w TG), $1250 (w/o TG) price difference between a 1030A and a 832 worth it??

From what I read on their spec sheets, the main differences other than price with the 832 over the 1030A are;
10 db improvement in phase noise,
DANL holds up to 3GHZ on the 832 where it drops 12db above 2.5GHz on the 1030A
Max reference level is 10db less,
RBW is 10Hz as opposed to 100Hz,
SHI is 10db greater (5db greater than the 815),
TOI is 4db greater,
2 lbs less,
1.5" x 1.8" x 1.2" smaller,
No battery option

[theatrus]

On getting the TG: I guess it depends if you have access to a dedicated network analyzer.

[videobruce]

I don't get the connection. The TG option is self contained within the SA. Some give you a CW generator option to use it at a fixed frequency.
In the case of this 815, for $200 you are major foolish not to get it.
