If you do RF, check it out.

No affiliation with Rigol. None. Nada.

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...

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.

It seems you have very little experience with repairing equipment.

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

And you never seen a teardown of a Rigol scope :-)

a fairly large used test equipment company ( www.techrecovery.com ) 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.

It seems the used equipment market is so much better at your end. I
recently restored a TDS544A but its hardly worth the effort from a
financial perspective. And I was extremely lucky someone offered a
working color CRT board for an absolute bargain. Perhaps it was the
shortest buy-it-now offering on Ebay ever :-)

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.

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.

I've done some repair work in the past but mostly the cases other
people couldn't fix. Nowadays I only fix equipment for my own use. Or
just convert the CRT or STN screens to TFT screens.
