Hi Nx-1997,
Very nice program.
I was able to use it with 82357B GPIB adapter but I have difficulties finding a correct serial cable.
Can you please publish the pinout of your serial cable (including the null-modem adapter).
I have a computer with a RS232 interface and I want to make a serial cable for it.
Maybe you can also include the pinout for the serial cable in the PDF user manual.

Hi, tomeo.gonzales

These are the serial adapters I have tested working and they are the only ones I have. I bought them from Aliexpress. The blue and the black one have the fake 340 chip and they both work just fine, no issues. The grey one is a UGreen branded, it has a genuine PL2303 chip and it also works just fine. The null modem adapter is a female to female one, also bought from Aliexpress.

The HP 34401A user manual provides the serial pinouts I believe.

Also, I highly recommend users to try and create these AR488 Adapters, these don't need visa software to function.

Thank you for your fast response.
I'll try to duplicate the serial cable from 34401A manual.
One more request: please, if it is possible,  add a menu entry to turn the front-panel display of the instrument on/off. ( DISPlay {OFF|ON} commands )

Nx-1997:
The Display ON OFF is already included. You can find it in the config tab.

Nx-1997:
I have updated the 3457A, 3456A, and 3478A software to have the same features as the 34401A software.

I also increased the Date Time Resolution, now date time values have millisecond resolution. This allows Excel to properly graph your data with Date Time X-Axis, if you want to. The custom cell format for date time is “yyyy-mm-dd hh:mm.ss.000 AM/PM”

I also updated the HP Data Log graphing utility to support this new date time format.

I also added another new graph. The Date Time graph is a scatter plot, on the Y-Axis is your measurement data and on the X-axis is their Date Time value.
