I want to use my Keysight 1000X in combination with a current clamp to monitor a slowly changing current over a few hours. The maximum time scale on the scope itself is 50s.
I just got a demo licence for Keysights BenchVue Oscilloscope, because I figured I could use that for just logging the scope data away on the computer, just like I would do with a multimeter over serial port.
But after playing around the whole morning I get the suspicion that it might not be that easy?
I have the possibility to "trace data" and can set a logging interval and some "requested points" (I'm not sure if that means data samples per screen capture or what...?).
But when I set the logging interval to e.g. 1s, it seems to take one complete screen capture every second, not one measurement every second. And although I try to export all of these captures as one long measurement, the export results just in a lot of individual excel sheets, one per screen capture...
Is there a way to simply log the data from the scope with a low time resolution (like 1 sample per second) as a continues datastream? If the software would even show some kind of liveview that would be best, but is not a necessity.
PS: I know, with these slow and long measurements it would probably be easiest to simply use a multimeter with serial/USB output, but I currently do not have a multimeter with logging capability at hand.

Such "cheap" scopes can be used for all sorts of creative uses like that.
Set to roll mode, and turn on a measurement of the parameter you want to log. Then have a computer poll that measurement value over visa. No need to fidget with run/stop cycles and waveforms.
It won't be super accurately time aligned, but it'll do the job.

Yes, that is what I ended up doing.
It took me some time to find a document with all the SCPI commands for the scope, but it was actually linked in the web interface of the scope itself...
