I just stuck an offer on a SRS 620, which is sold as seen. I'll take a
chance it works if my offer is accepted.
The 5370B is still the only high-performance counter that I own, personally.
SR620s are fine as far as they go,
Is it me, or do they look very cheaply made? I have never seen one for
real, but the photo I see on eBay looked more like a $200 Chinese
power scope.
I used an Standard Research SR-830 lock-in amplifier extensively
during my Ph.D. It was really nice to use. But the SRS 620 looked
rather cheap to me.
Don't judge it on looks alone. While I would have made a few design
aspects differently, I think it's a rather nice unit and it does perform
better than the 5370B.
but if they have any strong advantages over the 5370 I don't know what they
are. Spending more for a 53230A isn't necessary unless you have a specific
need for something that only it can do (and I don't).
I never really looked into it. I just made a low offer on an SRS 620 on eBay.
I am annoyed with myself for selling the 5370B.
I don't really have any immediate need for another TI counter - what
need I did have, has since gone. But if I could get one cheap enough,
I would.
If you find a SR620 for a good price, then it's definitly a good thing
to have.
Cheers,
Magnus
