It’s a lovely quality thing and some superb operator and service manuals all available online.
Blood pressure, blood oxygen, breath C02, temperature, ECG (3-12 lead) all monitored and logged automatically. Internal (chest open!) and external defib paddles, normal disposable defib pads. Bluetooth, ethernet and RS232 interfaces, 2 lithium battery packs with calibration function, continuous background self checks and results logging. Voice recording, voice prompts for AED mode, pacemaking, manual defib. Built in printer...
Astonishing things!
Boots up ready for use in less than 2 seconds, non of that Linux/Windows nonsense in these!
... and you're able to snag a deal on a dead one for a face transplant.
A box of fragments.
HP 66312A 0-20V/0-2A DYNAMIC MEASUREMENT DC SOURCE
Basically a DC power supply with lots of dynamic monitoring features.
Won for US $21.50 but it's heavy so the shipping (via ebay Global Shipping Program) was costly:
Domestic leg $65.45
International leg $61.28
Import charges $19.41
And then... it arrived massively smashed.

It could be worse. According to ebay on the phone just now, they are going to refund in full. Item plus shipping.
This means I get a free jig saw puzzle to try and piece together. Visually it appears all the electronics survived, amazingly. But powering it up will be the test. Most lucky: the VFD is intact. In fact the whole front display board seems undamaged, apart from some bent tabs on the spinner wheel sensor. So the thing may be salvageable. Though it's never going to look pretty.

Heh. Someone has never tried living in Australia and paying US to Oz shipping costs. In US dollars times 1.5 (USD to AUD exchange rate) plus our lovely 10% tax on the purchase PLUS the shipping. And if I ship via my reshipper in CA, ALSO the commie-fornia tax on everything passing through.
No, this one is living with it's scarred face, and liking it.
Update: Ebay did indeed refund both item cost and shipping. So the lesson is, if you receive something via ebay Global Shipping Program, and when you receive the parcel it looks even slightly like the contents may be damaged, take lots of photos of the process of opening it and checking the contents. I've not used GSP much yet, and the few previous times I did were OK. But it seems the system may have a black spot or two.
I have tested the Noise Level of my TDS3034 using all 4Chs with ;
Time Base : 2ns/sec ( min )
Vertical :1mV/div (min)
Acquisition : Envelope
Trigger Source : CH1
Trigger Coupling : DC
No Probe Connected
All CHs are GND'd
Is that Noise Level normal for this type of oscilloscope ??
I got a few THS3091EVMs on the cheap from Newark. Pretty cool little dudes to play with CFB and high speed. Not bad for $7 a pop.
TerraHertz: putting the bits back together will go reasonably well if you use the liquid styrene plastic model cement from a hobby shop. It’s typically methyl ethyl ketone or trichloroethylene, if it is available in Oz. MEK works best but it’s not available worldwide these days.
Had a similar problem on an HP E3640A, not as smashed as yours but it did go back together with minimal scaring.
It works!
Mostly anyway. There seem to be some rather weird/confusing custom configs. Need to read the manual, set it back to defaults.
Not easy to use like this, the buttons keep creeping off center.
The second is one of those fake Agilent USB HP-IB interfaces, from China.
... Not ideal, but good-enough so I can ditch lt4320 in favor FERD in my designs. Here is the datasheet if someone interested: https://www.st.com/resource/en/datasheet/ferd40u50c.pdf ....

Does it work well? I am looking at getting one of these and am a little gun shy.
