[volt-nuts] Solartron (aka Schlumberger) 7081

[Philipp Cochems]

Hi,

I wouldn't say the 7081 is in the class of a HP 3458A (7081 is much
slower, much more noisy and linearity isn't as great as the HP 3458A).
But, it is definitely better than a 3457A (which is also quite noisy).

Calibration via GPIB is very simple and should be done be most
calibration labs (I've done that a few times).

Best Philipp

> The 7081 is a really great meter if working correctly. It is up there with the Wavetek 1281, Fluke 8508, and Keysight 3458A. The only down side is the front panel connector, but I have seen it converted to Banana's. I think you will find it much better then the 3457A even with an upgraded reference.
