Then, when you request array A data, it will be the raw measurements for your sweep set up. Study the program, step through it and watch what the instrument does as you step through it. Thanks Dennis, I downloaded the drivers. Most things are documented in the manual. Good luck and happy plotting!

Then, when you request array A data, it will be the raw measurements for your sweep set up. Drivers are available here. You only see data for one marker at a time, even though two are displayed.

Message 1 of Wouldn’t you prefer seeing something like this instead? Please let me know. They are available at no charge as long as you don’t specify support for an NI product. labfiew

Beautiful HP 4194A Plots and Data

Also, do i need to make any changes in the subVIs to do a capacitance scan. All I need is, once I am done with the frequency sweep fro my experiment, I want the program to grab the data from the LCD screen and put it into a excel sheet or a txt file. I was wondering if anyone already has a program written for extracting the data and storing in a excel or a txt file. I would also to like output Cs-Rs along with the impedance as a function of frequency and was wondering if you could guide me to do that using your program.


The settings at right worked for me. They are the same that are available over comms, but they are worded a little differently. Message 4 of Message 10 of Create a folder for your plot processing and put these files in it.

Click the “add file” button next to the Data File box and specify where you want the. All you need to do is click Capture. Here are a few more examples click to see full resolution: You labveiw have to take the functions in the driver, add them to your program, and write the logging functions.

HP a Analyzer LabView Libraries?

It is an autobalancing bridge, which provides labvied wide range and accuracy, from Hz to MHz. Thanks a lot for the quick response. Unzip the file and run setup.

Good luck and happy plotting!

It was of great help and the program worked like a charm. Most things are documented in the manual.

Agilent Analyzer – IEEE (GPIB) Driver for LabVIEW – National Instruments

Message 2 of Only the log grid lines for magnitude are shown; the phase trace has no horizontal grid lines at all. A driver would have all of the instruments commands necessary to communicate with it. The problem is I have to write down each and every reading. With this one, you can get specific readings, or the whole sweep.


4194A Impedance/Gain-Phase Analyzer

It represents some of my early work, but it is functional. I am using labview for the first time, lahview I am trying to find where I can change the settings for the capacitance scan labviw output that as an array in your program. Veusz will start and display the data just captured. The program you supplied through this thread does a default kHz sweep for the impedance and outputs it to a spread-sheet and even plots it to the main vi.

I don’t have the instrument’s manual, or even the instrument, anymore.
