Re: Getting calibration equipment calibrated
For fun last night I characterized my bench DMM with my PG506 in DC mode. I was able to use the deflection error to determine that the entirety of the DMMs range held to within 0.2%. Up to the 100v

Re: Getting calibration equipment calibrated
I use one of these. And one can send it back for recalibration.

Re: Getting calibration equipment calibrated
Walter,
I second your comments. We had a “cal-light” lab. Two GPSDO’s and a HP3458 and a set of Julie labs precision resistors. The 3458 got the stds lab cal at keysight ($1800) and then

Re: Getting calibration equipment calibrated
There's a lot of stuff you don't need to do unless you want to.
Remember that the analog scopes you're checking, unless they have digital counters (7D15, et al), you're deciding whether or not you

Dennis, in your pictures I see about 3 periods of oscillation in 20 ns. Isn't that corresponding to 150 MHz in stead of about 300 MHz? (I hesitate to bring this up...).

Re: Getting calibration equipment calibrated
Hi Dave,
Ok that changes a LOT of things. If you have access to that lecroy you should be set to do the calibrations on all the plugins. A 6.5 Digit DMM is plenty for the PG 506 did mine on a keithly
