Query Rigol Oscilloscope stats in Go

This tool allows you to pull measurement statistics from a Rigol Oscilloscope over the network connection and outputs them in CSV format. I've tested it with my DS1054Z so far.

It can also take screenshots at the same intervals.

Usage

# go run .\rigol.go -host 192.168.7.90 -channels 2 -clear -interval 60 -vmax -vmin -screen > file.csv

Options are as follows. If you have more than 5 statistics displayed (on my scope at least) then reading them takes a few seconds as it has to recalculate the values as the others scroll off the list.

-channels int
        number of channels to collect (default 4)
-clear
        clear stats after collection
-count int
        number of measurements to take. -1 = no limit (default -1)
-freq
        include frequency
-host string
        hostname or IP address (default "rigol")
-interval int
        number of seconds between readings (default 1)
-port int
        tcp port to use (default 5555)
-screen
        collect screenshots in PNG format
-vavg
        include Vavg (default true)
-vmax
        include Vmax
-vmin
        include Vmin
-vpp
        include Vpp
-vrms
        include Vrms

Setup

You can configure the scope over the network too - this is especially useful if you want to set specific options across a number of tests.

I use the following example quite frequently - telnet to the scope on port 5555 and send the following commands. It's worth doing a few at a time or sometimes one will get missed if you paste in too many lines at once.

Detail for these can be found in the Rigol Oscilloscope Programming guides, but in summary this sets the scope to a rolling 60s view, reading a range of -0.5 to 3.5A on Channel 1 and -1 to 7 V on channel 2, and enables the cursor for realtime measurements.
