This pretty much wraps up Python Screen Capture of RIGOL 1054Z on macOS Catalina Using NI-VISA.

Hope at least one RIGOL user finds this helpful.


Python Screen Capture of RIGOL 1054Z on macOS Catalina Using NI-VISA-noise_blue51jpg


Final capture at the standard 800px width (versus the 1024px width I have created by enlarging 800px to 1024px width). JPG capture.

Note, the best way to get JPG capture to work on this RIGOL is to specify the JPG file type in the LXI command; but name the file with the .jpeg extension. This works best, consistently, for JPGs for some reason yet explained. But, if you don't want this confusion, go with BMP images, which are consistently better, with the BPM24 option, and file extension .bmp.

REORDERCAP(1)						  The Wireshark Network Analyzer					     REORDERCAP(1)

NAME
reordercap - Reorder input file by timestamp into output file SYNOPSIS
reordercap [ -n ] <infile> <outfile> DESCRIPTION
Reordercap is a program that reads an input capture file and rewrites the frames to an output capture file, but with the frames sorted by increasing timestamp. This functionality may be useful when capture files have been created by combining frames from more than one well-synchronised source, but the frames have not been combined in strict time order. Reordercap writes the output capture file in the same format as the input capture file. Reordercap is able to detect, read and write the same capture files that are supported by Wireshark. The input file doesn't need a specific filename extension; the file format and an optional gzip compression will be detected automatically. Near the beginning of the DESCRIPTION section of wireshark(1) or <http://www.wireshark.org/docs/man-pages/wireshark.html> is a detailed description of the way Wireshark handles this, which is the same way reordercap handles this. OPTIONS
-n When the -n option is used, reordercap will not write out the output file if it finds that the input file is already in order. SEE ALSO
pcap(3), wireshark(1), tshark(1), dumpcap(1), editcap(1), mergecap(1), text2pcap(1), pcap-filter(7) or tcpdump(8) NOTES
Reordercap is part of the Wireshark distribution. The latest version of Wireshark can be found at <http://www.wireshark.org>. It may make sense to move this functionality into editcap, or perhaps mergecap, in which case reordercap could be retired. HTML versions of the Wireshark project man pages are available at: <http://www.wireshark.org/docs/man-pages>. AUTHORS
