Keysight's new 34465A (6.5 digit) and 34470A (7.5 digit) bench multimeters
idolclub:
Keysight Releases New Firmware v3.01 for 3446xA/70A series.
Firmware Update 3.01 Release Notes:
34460A/34461A/34465A/34470A Revision 3.01 Enhancements and Fixes:
1. Improvements to reduce the occurrence of a memory leak associated with LAN traffic that occurs when the DMM is connected to a LAN network but remains idle for several days.
2. Changed the 100 kΩ range calibration to internally select 100 NPLC rather than 10 NPLC to better reject noise associated with selected Fluke 5730 calibration values.
3. Removed Option AVG from the list of available options (Help – About window) as it is not available to all customers.

Too bad not a major update with enhancements.
But good that the LAN problem was fixed.
Did we ever find out what this AVG option was all about?
As its seems now, it was only for selected customers.
Dr. Frank:
Hello HighVoltage,
yes, about the AVG option, it's been answered here:

HighVoltage:
Thank you Dr.Frank, I had not noticed this.
This was the answer:
--- Quote ---The 34465AVG AC average function is a special option that was done for the Navy that you shouldn't want. The Navy wanted to get matching results that are given by some very old analog voltmeters before good RMS converters were available. The 34465A true RMS AC voltage function gives a much more accurate RMS voltage. In any case, the AVG option is only available to the Navy. It was a mistake to have this show up in the Help > About window.

So, it seems, Keysight has a special firmware for the Navy. And may be other large customers.
Very interesting.

Just to give back to the eevblog community:
A little python script leaking measurements into the clipboard.
Requirements:
* DMM which understands SCPI and is supported by pyvisa
* Python 3 intepreter with visa, pyvisa and pyperclip packages installed
* LAN to your PC
* clipvolteev.py file with your DMM IP Adress ath the DMM=rm.open_... line
You enter the query, a multiplier (if needed) and if you want CR-terminated string in the clipboard.
Your trusty DMM will start cyclic measurement and you can e.g. write reports and get the most recent measurement into your report by pressing Ctrl-V.
With CR termination (j) its -0.000
-0.000
-0.001
-0.001
-0.001
-0.001
Without CR termination (n) its -0.000 -0.000 0.000 0.000 0.000 0.000 0.000
Tested with a 34461A.
