Rigol DSA 815

This is a moderately priced spectrum analyzer covering 9 kHz to 1.5 Ghz with a tracking generator option.

If you do RF, check it out.

No affiliation with Rigol. None. Nada.

It seems right nice for the price point. But for my use case Jan P.'s design is a better deal.

I still think that 1.5Ghz is marginal with today's gear. Either a block converter or one that can do at least 5Ghz would be more appropriate.

It would be nice to be able to at least look at the common 2.5Ghz band.

I have looked at that unit and while it has some nice standard features and a good paint job, I think I would rather throw in some more money to get one that does at least twice the BW.

Just my opinion from the peanut gallery....

Why do you even think about buying from a spammer?

He has nothing to do with the company, so he's a troll.

No thanks. For a little more money ($3K) I could get an Agilent 8562A good to 22GHz.

So $3K is just a little more money than $1,295 ?

Nice to know your reference...

He's right, if he needs the extra coverage. Otherwise he has to buy a bunch of other cheap gear. It is a real pain in the ass to have 50+ pieces of equipment on an 8' bench, a table & multiple equipment carts. It lowers your productivity quite a bit, which will cost a lot more than $3,000 over a year's time.

In addition to what Michael said; When and if something goes wrong with the HP, I have the complete set of service manuals with component level information - I can fix it myself. Parts are plentiful for the HP as well. What about the Rigol?

By the time your Rigol breaks down, Ebay will be swamped with 'for parts' units.

All needing the same parts, or they wouldn't be on Ebay.

Probably. I wouldn't be surprised if it consists of 1 or 2 circuit boards loaded with all sorts of chips that cannot be removed economically (BGA, etc.) by your average tech. And with no service data, you likely wouldn't be able to figure out what needed replacing anyway.

Very few can troubleshoot something like that, unless they have piles of the same dead model, and excel in logical troubleshooting. I would think it would be well under 1% of all electronics techs who would be succesful.

It seems you have very little experience with repairing equipment. What breaks most often is the PSU, inputs or outputs. These are mostly built around standard chips and easy to repair (especially true for modern low and mid range equipment). If the logic gets defective it is usually caused by the power supply going wrong. And then there are the occasional bad solder joints but those are rare. All in all most equipment can be serviced even without a service manual as long as you think logically.

well.

You have'nt worked with much 'Lead Free' repairs, have you?

It's not so much the first converter, as the first LO, that would add to the cost. Continuously, linearly, sweeping over a 5GHz range is not exactly cheap.

You'd be wrong in your assumption. I've probably repaired more test equipment in my life than you've ever even seen. I worked for 3 years for a fairly large used test equipment company (

) as their only component level tech. When I realized I could make a whole lot more money buying broken equipment, doing the repairs, and reselling on Ebay, I left them.

Although my stock is a bit low at the moment as in Jan and Feb I sold over $25K worth of equipment, if anyone sees anything they like, I'd knock 10% off on a private sale. ;)

At this point there are several used equipment dealers who send their stuff to *me* for repair.

Of course.

Sometimes that is true, but many times not. I've seen just about everything under the sun go wrong or bad. Likely because I've repaired thousands of instruments.

Neat! Say the four channel Aglient 'scope 54831B for only ~$600 looks like a steal. Is this 600MHz? Is there something wrong with it? (I wonder if my wife will let me buy another 'scope?)

Re the Rigol: I think Dave did a tear down of it on his eevblog.
