Also, note that many of the scanned pdfs offered at a modest fee by 300a e-manual companies, have scanned them at very high quality as compared to most of the free downloads which are generally scanned at relatively low resolution. Jim Williams passed away the same Sunday that I was writing my first notes on high crest factor measurements.

Probably all of the foam inserts are decomposing by now. The item may have some signs of cosmetic wear, but yp fully operational and functions as intended.

Remove all of the old insulation foam, including the adhesive paper tape at the bottom of each plastic slot. We will notify you as soon as this item is available for purchase.

I have no direct experience with the earlier models. As well documented, for example, by Jim Williams and Todd Owen of LTC [5], average responding meters do not directly measure noise correctly. The lowest-priced item that has been used or worn previously. Please contact us via email 34400a toll free at and we will be happy to assist you with this request.

The manuals for the hp A are widely available hhp the Agilent website and other manual down load sites, so we have not re-scanned or re-posted it here. Recently, the availability of late model e. For example, numbers were over 32, by the year It shows some wear as pictured.

An input AC signal is 3400a conditioned by an AC amplifier of appropriate bandwidth and applied to heat a heating element. True, temperature gradients across a chip can be an issue. But, then one would also need to confirm the stability of the input ACV amplitude as well as the thermocouple-heater pair.

Please provide the requested information to receive an estimated shipping cost.

See also their main gallery. The still available Linear Technology LTC appears to be a good alternative without modification where repairs of the later model A A6 boards are needed. There might still be a place in the Lab for this Forgotten Meter. Please let us know which of these you would be willing to consider for the price discount. Yes No Are you willing to prepay your order by check or wire transfer to avoid credit card fees?

Doing that will ensure that you don’t overload or damage the meter. 34000a temperature of the first heating element is registered by a first thermocouple. If you are looking for a late model A series from and some later years, the only way to be sure might be to see the prefix in a picture of the rear panel or to ask the seller.


Skip 3400w main content. So, these ACV meters with wideband 4300a amplifiers, are non-the-less relatively slow in response time, presumably one of the reasons beyond cost that this thermocouple technology is no longer used.

The original 10 MegaOhm input R was provided by a nuvistor vacuum tube in a small metal can RF amplifier. Correct Issue Close Wizard. Jim’s absence will be a huge loss to the Analog design community.

See details for description of any imperfections. See all 9 pre-owned listings. Symptoms included significant movement of the meter needle and low sensitivity. Requirements Our normal service up 90 day warranty, all standard accessories and manuals, and restoration to “nearly new” condition.

I do not know what serial numbers changed over from the nuvistor to the JFET input, or from the neon bulb chopper to the intersil integrated chopper might be 34000a the manual changes somewhere; I think the came out aroundnot sure. However, as noted by Horowitz and Hill [6], for Johnson noise measurements, a small correction factor does the job.

A “balancing” amplifier applies whatever DC voltage is needed to a second heating element attached to a second thermocouple to match the temperature of the first heating element.

If you are going to clean the rotary switch with Deoxit D5 Caig Chemicalsfollowed by P5 highly recommendedthen use a small wire tie to tie the A3 board off to the side of the chassis to keep it out of the way and stable during rotary switch cleaning.
