One thing that strikes me reading old 3458A product datasheet from HP is that they stressed the high measurement speed, 100kHz @ 16 bit, but not empasizing much the DC accuracy. Now, the 3458A remains state of the art in DC accuracy / liearity, but for high speed measurements and of course frequency, the 3458 is now nowhere near state of the art any more.
As Tom pointed out there is a lot of characterizing around the 3458 and also a high trust from other manufaturers. For example I have a precision SMU and the calibration procedure is explicitly and with detail, pointing to the 3458. On price: basic price was perhaps once set by development and materials cost. But after 25 years, a sales department sets the price, to whatever they think is most profitable.... _______________________________________________ volt-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/volt-nuts and follow the instructions there.
