HP 3400A RMS Voltmeter
Additional Info Please let us know any information that will help us fill your requirement such as urgency, quantity needed, etc. The first chopper stabilized circuits used a galvanic break of neon bulbs to cadmium sulphide cds photo cells. As well documented at other sites, there has been an evolution of the HP A series meters from their introduction inthrough the late s ending with the B. Another approach might be to do the test with two or more A and move the A6 board with the socket between the units in separate test runs over temperature.
Additional Info Please provide any additional information which could help us determine whether we can meet your requirements for this offer. Remove all of the old insulation foam, including the adhesive paper tape at the bottom of each plastic slot. However, as noted by Horowitz and Hill , for Johnson noise measurements, a small correction factor does the job.

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 in the manual changes somewhere; I think the came out aroundnot sure. An input AC signal is signal conditioned by an AC amplifier of appropriate bandwidth and applied to heat a heating element.
Fortunately, we had two suitable replacements on hand and all is well now. Early and mid production models used the traditional numbering scheme A nnnnn. Requirements Our normal service includes 90 day warranty, all standard accessories and manuals, and restoration to “nearly new” condition.
Please enter your offer below for consideration. Place the unit on its side during spraying, so the A2 board is on top and does not get sprayed.

This makes it superior to conventional analog and digital voltmeters where regular analog meters top out at 3 or 4 Mhz and where DVM’s often top out at Khz. It shows some wear as 3400w. The temperature of the first heating element is registered by a first thermocouple.
We would also greatly appreciate it if you could provide us with this error code: Some hours later I care hhp admit how many! The A with the socket easily calibrated to spec. The manuals for the hp A are widely available from the Agilent website and other manual down load sites, so we have not re-scanned or re-posted it here.
A RMS VOLTMETER [Obsolete] | Keysight (formerly Agilent’s Electronic Measurement)
The up available Linear Technology LTC appears to be a good alternative without modification where repairs of the later model A A6 boards are needed. This item doesn’t belong on this page. One caution that should be observed is that the thermocoupling circuitry can be damaged by excessive overloads more easily than conventional meters so always start the meter at a higher voltage setting and then scale down to the range to be measured.
If the description says needle moves and the picture shows a needle indication above the first mark, plan on a high likelihood of repair! 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.
Jim Williams passed away the same Sunday that I was writing 3400x first notes on high crest factor measurements. Please correct the issue indicated and resubmit or contact us via email or toll free at and we will be happy to assist you with this request. It might not be such an easy project!
Unable to Process Request Your offer was received but we are unable to process it for 3400aa following reason: We hope to earn your business. Symptoms included significant movement of the meter needle and low sensitivity. Understanding and selecting rms voltmetersFailing to verify 3400x accuracy before conducting rms-noise measurements may cause highly misleading results, Jim Williams and Todd Owen, Linear Technology Corp, EDN, May 11, This could be done, perhaps by monitoring the DC output level of the chopper amplifier e.
