Was having some fun probing current through a resistor using my B2901A SMU as a source.

Nice!
The 1147B is a really nice probe.
And the zero correct function does work much better than on the 1147A.

Interesting - I don't know why but I thought the main difference was just RoHS compliance between the A and B.

I am sure there was a redesign to correct the zero reference but I have no confirmation for this.
Because every 1147A I had was not correctable with the wheel and some had a large offset and needed repair.
And every 1147B I had was perfectly adjustable around zero amp with really good accuracy.

Here is where I show my first 1147B repair:

Hey @nctnico - my local agent was asking for over £4,000 for the Keysight 53230A so I looked at eBay and went for this 53132A, which is a little over £1,000/-.  Will let you know how this pans out, thanks.

Time to bump this one up again  :-DD

Finally bit the bullet and bought a LeCroy DDA120 off of ebay as a parts unit, no testing, no line cord etc etc.  I figured I could use the power supply to repair an LC584 that's been apart on my bench (also bought as a repair project).  If I got a power supply and the CRT I figured it was well worth it.

Plugged it in and turns out to be 100% functional.  I think the "Disk Drive Analyzer" moniker throws non-technical people and they have no idea what they're dealing with.  This one came from Maxtor by way of Dovebid.  The seller probably bought a pallet of them, they've been sitting on ebay for months.  Every month or so I'd do the rounds sending out offers and finally got a bite.

Now I can bundle up the 584 and put it on the shelf as parts and start looking for a set of probes (which will probably cost more than the scope).  That makes for one easy repair.

Yes it's big and heavy and a little loud, but I have the bench space, it has tons of math options + FFT and where else are you going to find a 8Gs/sec color scope for $300?
