HP 34401A 3457A 3456A 3478A Standalone Software

You often need to collect data from sensors.. Sure, you can get a 3458A for each temperature you want to measure, but sometimes $3 solution with ~1mK resolution could be enough

A $3 solution that may take a couple of days to make.
If I need a solution for a few hours I prefer to use standard parts (This includes DIY sensors) to set it up, but when used for longer time a simple program in a microprocessor may be a much better solution.
Because I have a pile of PC's (laptops) and I need the final result on a PC, I usually use a PC for my data collection.

Grapher - works nice!
My "nice to have" suggestions:
1. the formatting of the Y axis - would be great to have constant number of decimal digits (like 10.123455, 10.123450..)
2. ppm math - like PPM (Sample - Y)/Y *1e6, or something like that..

Wonderful job and thank you for sharing! 
This works fine on my HP3456A and an AR488 interface.
I had to activate the flow control via xon / xoff otherwise the connection failed systematically!

Nx-1997   Thank you for sharing.

IMO you have created a nice simple intuitive and easy to use GUI.

Within minutes I was able to have 3x 34401A's logging data with a real time graph. Exactly what I was looking for.

Question If I want to send a command to turn off the VFD display, is there a way to send a command while logging?

[Nx-1997]

In the Config Tab, click the Display Tab then click the Off button. You can send any commands while logging.

Your animated .GIFs are awesome! 

Nice shit! Congrats.

Side questions....

Can you tell us what to you use to create the gifs?
If everybody on this forum could be a gif ninja like you....

Game changer....

Nx-1997,
I really like your program, It works perfectly on my Win7-64 machine. I'm now trying to get it working on a Win10-32 tablet and have a hiccup. My guess is that I'm missing some aspect of the NI-VISA let me explain.

When I installed NI-VISA on my 64 bit machine, I installed the latest version 21.0 and NI installer offered about 10 optional (not sure if they were applications or drivers), they were all ticked by default so I just let it install everything. It took a while. this version works.

When I tried installing version 21.0 on my 32bit flavor of Win10 on the tablet, Windows complained that the installer requires at minimum a 64 bit version of Win10. So I instead installed NI-VISA version 20.0 and this time I unchecked all the extras (I probably should not have done that). I proceeded as before however two issues were obvious:
1) In the Conflict manager I don't see National Instruments VISA.NET Resource manager under VISA.NET
2) I was also missing NI-VISA Interactive control application, (this was likely one of the ticked applications that I un-ticked) I added this after the fact, ran it and it now acts like before, recognizing the 3 connected devices, however  most likely I'm still missing something else and when I try to connect using your application I get a Windows error, see below.  I'm going to try to uninstall NI-VISA and then reinstall with all the "optional" tick boxes ticked and see what happens.

Well I tried installing all the optional add-ons, and same thing, so I'm guessing this might be a 32bit vs. 64bit compatibility issue?

UPDATE:
The program is fine, the problem was Win 10 updates!

I tried a few things nothing helped and then I tried a full Windows update and it started working.

Hi Nx-1997
I wanted to thank you for making the programs available. They work perfectly on my laptop with Win10 enterprise 64bit.
I connected my HP3456A and HP3457A with AR488 (GPIB to USB ver 0.51.03_19.01.2022) interfaces to usb on
Raspberry PI4 (4GBram), Raspbian GNU/Linux v.11 (bullseye) 5.10.92-v7l+ #1514, RealVNC server 6.7.4.
In the system runs ser2net (4.3.3-1) which allows to access virtual serial ports on different IP
ports (two AR488, one Korenix JetCon 1104 with four RS232 to usb converter, one Prologix converter), also on raspberry
a Agilent 82357B and BME280/SMBus, one rs232 port interfaces the gpsdo trimbolt for remote data to Lady Heather's (thank to KE5FX). 

On a Pc/win your programs see the instruments on the virtual serials made available by Perle TruePort v6.9.

I connect them from a remote site via vpn,and everything is working fine with an excellent GUI. 

As soon as I have some time I try to try the software also through Visa GPIB.

Thanks again for making this software, it's always a pleasure to use! I used the math function to generate some scaled data. This made me think that next time you are playing with it, it might be easy to add a mathematical equation to derive temperature from an RTD, thermistor or a thermocouple. You could add a general equation for each type of temperature sensor and let people program the constants or maybe have some standard constants pre-programmed.

With 34401 & 3478 you can use TestController, it supports this.

So I decided to try out this software with a laptop my friend gave me. It's running windows 10. After getting a serial to usb cable from amazon, and then having to DIY a null modem connector, the meter and the software without an issue.

I did make sure to get a serial to usb cable with a Prolific PL2303 chip.

Pretty impressed with this. Would love to find something that I can use with my HP 8591E spec/an.

One question I have though is about the "speech" function. Is it not working, or, do you need something special outside of windows audio to hear it?

Hi  i've seen you 34401a control software

Since i'm a github noob for coding,  it was compiled on witch platform,  visual basic,  Dot Net 

Just acquired an L4411A  and want to do the same,  but  for now it talk with  with agilent DMM_Connectivity_Utility_1.0.2.0.exe and the connection is done thru usb

(gonna have to buld an AR488)

With Keysight i/o librairies, i think i have all the  scpi commands in to some files

thks

Thanks a lot for sharing such an amazing project.
I was trying to connect with my HP3457A but not getting any response, but when i check GPIB version using ++ver I get

Fenrir GPIB-USB 1.0 (Prologix version 6.0 Compatible)
 
On my DMM 3457A address is set to 22 but I want to know, how do I figure out baud rate, or troubleshoot the connection.
