I upgraded from my 8566A...
...to a brand spanking new old stock 8566B. To say I'm excited is an understatement. It's perfect. No scuffs, scraps, dings, or dents. And it has everything. The pull out cards, manuals, application

Agilent DSO-5012 "User Cal Failure"
HI All.. I just obtained an Agilent DSO-5012 which I thought would be a great scope for getting familiar with the use of Digital Scopes. I understand the principles of sampling etc., so that is not an

Re: HP Agilent 34330a current shunt
I did specifically suggest a standard 50mV 50A (north american) or 60mV 60A (European) shunt as they hav the same 1mv/A scalling as the 34330A. It's not too much trouble to put one in a small plastic

Re: HP Agilent 34330a current shunt
Fluke makes a similar shunt rated at 20A for a minute: 80J-10 FLUKE 10A 100mV SHUNT

Re: HP Agilent 34330a current shunt
Speaking of buying it new, I found it at Mouser priced at $101 which for me is one of my most trusted and reliable parts suppliers.

new VXI board ejector handles
Hey folks. Since I went to a bit of trouble to identify these and took the risk on purchasing some to test for compatibility, I figured I'd share this with the group in case anyone else needs some,

Re: Wanted: HP 3458a DVM in non-working condition
George, Thank you again for your detailed answers. On the subject of a voltage reference upgrade, I do have a couple new LM399s laying around that could potentially be a drop-in vref replacement,

Re: HP Agilent 34330a current shunt
I went to look at the new price od these, and I find that Newark will sell me a new one at anywhere from CAD 130 through >CAD 400 ( https://canada.newark.com/search?st=34330a). The price difference is

Re: Wanted: HP 3458a DVM in non-working condition
A parts unit just sold for $3250! The serial number is old, 9918. (Item # 402001351594) One plus is that the error flag is not on, but that can be cleared and have it look like it has no errors.

Re: HP Agilent 34330a current shunt
Thank you everyone for their input, specially to Yves. Yes a cheap shunt will give you a current reading as well as anything else but it needs to be wired into the circuit, requires some conversion

Re: Wanted: HP 3458a DVM in non-working condition
Siggi, You are correct.? The Ohms current source and protection that I developed has never been improved upon.? It has been incorporated in every instrument since the 3468A/78A.? ?It is robust,

Re: HP Agilent 34330a current shunt
Just from the photos those cheap ebay shunts are poor quality.

Re: Wanted: HP 3458a DVM in non-working condition
Dennis, The most challenging aspect of the analog design for me was the overvoltage and? ESD protection of the Ohms converter current source using a minimum of CHEAP off-the-shelf parts.? I spent

Re: HP Agilent 34330a current shunt
There are low cost Chinese shunts available on ebay. For a few dollars more you can get an LED voltmeter/ammeter with a shunt. I haven't tried them.

Re: HP Agilent 34330a current shunt
I got mine les than a year ago on the auction site, less than $30 and free shipping. New condition, too. If you¡¯re not in a rush it pays to watch for a while! Love it and although it doesn¡¯t get

HP 70210C Spectrum analyzer
I've decided that my HP 71210C analyzer is way more than I will ever need anymore so I've decided to sell it. This is a 100Hz to 22GHz unit, works great passes all self tests and calibrations.
