Again a bit of a tangent, but firmware version 3.0 now includes the digitizing and advanced trigger (former option DIG) as standard.

I had my 34465A running over night with a short block on the input.
Here is the histogram for comparison.

Hi HighVoltage,

The histogram of your 34465A is really nice. Before starting collecting the samples for the histogram, how long has the 34465A been powered (warmed) up?

Thanks

Hello dmm2018

This 34465A was turned ON for about 24h, before I started the data collection for the histogram

Thanks HighVoltage...

I tried to produce a similar histogram plot for my 34470A. I found it's not easy to obtain such a nice bell-shape curve for my unit. I noted that the different orientation (rotated 10-30 degree) of 34470A will affect and shift the mean of the histogram plot quite obviously.
