I would like to measure the current/voltage of my system and save the data to my computer. The instrument (Agilent 34410A digital multimeter) speaks the SCPI language. How can I save the measured data to my computer?
Dear Blake Bryson,
There are two options in the agilent 34410a. Through internet and another is using GPIB. In both cases you need to send specific command to read logged data. I recommend if you have GPIB connectivity use it. Please go through the manual attached which clearly describes the process.
Hi Blake,
many years ago (in 2003) I made my HP34401 multimeter (is it similar?) to send its readings to PC using RS-232 connection (with twisted-swapped pins 4 and 5) and special software:
As per our conversation, here's the link to download the software. It's 10.6MB in size

Let me know if you have questions. Thanks for your call

Name of that software is Intuilink - it can send multimeter's readings directly to either to Excel or Word
Using the SCPI commands you can use a free environment like octave or python that has an instrument control "toolbox". You need to connect to the instrument using one of its three available interfaces: the usb or the ethernet interface, or even the gpib interface if you have the appropriate adapter.
in python https://pyvisa.readthedocs.io/en/latest/
>>> import pyvisa >>> rm = pyvisa.ResourceManager() >>> rm.list_resources() ('ASRL1::INSTR', 'ASRL2::INSTR', 'GPIB0::12::INSTR')
#listing the connected intruments >>> inst = rm.open_resource('GPIB0::12::INSTR')
#connects to the instrument avalable on GPIB0::12 but cand be ethernet or usb >>> print(inst.query("*IDN?"))
#send the idn query and expects the intrument to send the identity information.
for octave/matlab

To set up your measurement you need to check the remote programming guide.
