Troubleshooting Analog Circuits - Robert A. Pease
and on the opposite, a bunch of digital TTL ICs

[PlainName]

Perhaps someone somewhere has bought "Troubleshooting Digital Circuits" along with a bunch of analog chips, and you can do a swap.

I finally got around to getting a Herman Miller Aeron! Can't wait to replace my crusty IKEA Verksam (which surprisingly held up OK for six years).

Just received one of @Venturi962 USBGPIB adapters. The housing is very nice and it works flawlessly on my HP3478A.

Got one of those novelty component testers from AliEx after 2 failed Amazon attempts. $10 cheaper too.

Congratulations in finally getting yours after such frustration. Despite what is mentioned in the news, it seems the logistics of the world are finally getting its pieces together.

I have 3 of them AliEx component testers .  the first two are not in case types so one got d when it dropped of the work bench cracking its LCD display.
but the one in a case like your unit shown here with its own Li-ion battery, is still going strong   the other non case unit is in good condition but does go to eating 9volt battery's .
best component tester value for money ever!

A 10-pack of Bourns 10µH inductors also was in the box; I'm going to tame buck switchmode regulators..

A 1.2V backup battery.

This is to replace the 1.2V backup battery I bought at the beginning of the week, which arrived yesterday, and which got teleported up by aliens between being unpacked and put in my pocket for safe keeping during the walk to the office, and finding empty pockets later in the day when remembering I was meant to be fixing the battery backup thing.

Scored myself a nice HP 4140B on Ebay, $290 delivered.  The last cal sticker is mid 2016.  Both voltage sources check out accurate against my K 6500 as well as their respective current limit functions.  Offsets on all ranges are in the range of +/- .003.  With a very rudimentary high resistance setup I was able to confirm current measurement functions.  Now I need proper fixtures and cables and will officially have my toe in volt nut waters.

Just got a FY 8300-S 60MHz from Banggood $130 incl VAT + Ship.
10 min later the price was $210 + Ship

Can they measure FET pinch-off voltage?

Currently showing £74.60 (inc VAT) for me ($102,  €89.43).

Edit: but 'sold out'

Is that a triax connector I see on the "I input"? If so, welcome to the triax club. It's an exclusive club for those with a little bit of money to spend on test equipment connectors and cables....

N.B. that there are various different triax connector standards and watch out for connectors/cables that connect various contacts together.  Both are traps for the young players.

Yep, 3 slot triax. I had no idea how expensive those are, but I have a few do dads on the way. I almost fell into the 3 (very expensive) vs 2 (somewhat expensive) slot trap.

Mine just seems to measure Vgs (gate threshold voltage) but not pinch off.
It's a basic tester and component identifier. It's limited by the fact that the test voltages are less than 5V (Except for the zener test which is 30V max) and the currents are low. (5ma or so)

A Tektronix 7A22 and a 7A13. Both sold as spares but after first check out working. The 7A22 has some crackling switches but the 7A13 seems completely fine. Ten minutes after testing the new plugins one of the 7A18's let out the magic smoke - a short on the 5V rail fried a small choke. Oh well, you win some, you lose some  .

Gotta find that fault now, at least the mainframe is fine.

I wish it was that easy. Threw out all the tantalums years ago  . Something else created a dead short, don't know what yet.
