The 34401a is a excellent and the GPIB interface for VBA software control and data collection is really nice .
new ones will be spendy, used ones on ebay are a gamble. be prepared to fix them, as i had to with a recent ebay 34401a.
the ebay gdm-8251a tick every box for OP's requirement, are cheap, basically brand spanking new, and known to work. it's really a no brainer. lowball the seller and walk off with a $90 5 1/2 digit dmm.
Looks like a nice Agilent clone, but you are stuck with a Chinese meter. I don't know if you could find a lab to NIST certify that brand. If you are using it for work or equipment calibration, I'm sticking with Agilent/Keysite or Fluke.
It is strange to have that USB connector on the back. I don't have and flat USB to flat USB cables.
If I had $100 burning a hole in my pocket, I would order one for shits and grins.
Why would a used Agilent off of EBAY always need repaired if it has a 14 or 30 warranty/return policy?
Is it bad to buy any test equipment off of eBay?
In two weeks I am going to buy a Agilent 33250A, two scope GPIB interfaces, Agilent Attenuators, etc,. Maybe I should get nothing from ebay?
I was going to have a cal lab cett the equipment as soon as I got it. If there a problem, back it would go. I see some sell it with a NIST cert. I emailed on and for about $100-$175 more, I could get the equipment with a new ISO 17025 accredited cert. If I do that, I would think I am somewhat protected against buying duds.
Now Yaa hot me worried. I wasn't going to buy the cheapest I could find. I was going to look for equipment dealers.
