Methodyn Oskar

A program to acquire, process and plot data from the Tektronix 7854 oscilloscope.


- Automatic detection of GPIB adapters and instruments during program start
- Several GPIB adapters can be used simultaneously
- Multiple instruments possible
- Acquire, download and display waveforms with all params
- Display waveforms in vector and dot mode
- Show Rise- and Falltimes of each part of the waveform
- Displaying scope aquisition area or scope display area
- display multiple waveforms
- Supports all 7854 aquisition modes (AQS, AQR, AVG)
- Store / load waveforms
- Print waveforms landscape/portrait
- Adding comments to waveform
- Comparing of waveform paramters
- Sending text to the 7854
- On-Screen keyboard for the 7854 main unit
- On-Screen keyboard for the 7854 Waveform Calculator
- On-Screen keyboard for the programmable plugins 7A16P, 7A29P and 7B90P in the 7854 (GPIB Decoder plugin 021-0374-00 needed).
- Uploading calibration helper programs of the 7854 (see sections G+H of servcie manual)
- Displaying scope aquisition area or scope display area
- Readout display
- Draws important waveform params (0/10%/90%/rise/fall)
- Free selection of of most drawing colors
- Line weight selection
- Command-line option: open one or multiple files ("-o" + "Fullpath")
- Command-line option: do not Scan for Instruments ("-noScan")

System requirements:

- Windows Windows 7, Windows 8, Windows 8.1, Windows 10
- National Instruments GPIB Adapter or HP/Agilent/Kesight GPIB adapter (mixed environment possible)
- Installed GPIB driver (2014 or newer needed)


- Physical Windows PC required - no virtual machines supported
- Genuine GPIB adapters required - no clones supported

Actual state:


Future plans:

- Translation
- Reload waveforms back into the 7854
- Adding FFT functionality to the 7854 (via program)


My test environment:

Fun with the 7854 part I: Surprise after connecting the 7854 to the internet

Fun withn the 7854 part II: Measuring AC ripple in the DC universe
