HP 3458A is a little bit noisy. @marcoreps@bird.makeup has already observed this on other 3458A. Who has that too?

From prototype to product. But somehow the product is still a prototype.

That would be a good candidate for a display replacement. A Fluke 5442A Direct Volts Calibrator.

@n8dmt@mastodon.radio I've had a setup before. Will make a video. https://social.tchncs.de/@BoscoLab/111555816912651683

The HP 8350B with the 83522A plugin is drifting. There's a setup to keep the frequencies stable. The HP 5343A and 5344A are available for this. I'll rebuild the setup.

A quick review of the multimeters HP 3455A and 3456A with my own highly accurate resistance standard. I will soon build some more to order.

Please be quiet, the HP 3458A must not be disturbed.

I set up the first devices in the new laboratory. The electronics laboratory is now fully air-conditioned. Stable temperatures for calibration. Soon the work tables will be set up. #hp #agilent #keysight #tektronix #rohdeubdschwarz
