JaredParticipantIt would be nice to be able to do some approximate burst timing on the 2D/3D plots.
A simple time scale?
A trigger based time measurement?
Cursors?The zero span doesn’t have the time span to cover it sufficiently last time I checked…
Am having intermittent USB connection problems
AndrewModeratorHi Jared,
We have talked about updating the 2D waterfall plots to include more functional measurements. We are aware of the limitations of this plot in its current implementation. There is no time frame on this yet.
You are looking for a long triggered capture? I am currently expanding the functionality of zero-span. I am adding more flexible/adjustable plots, increased capture times, and long term IQ recording/playback through the Spike software. If you could detail your requirements a bit more, I might be able to determine if this functionality will address your needs.
What kind of connection issues are you experiencing? Intermittent disconnects? This is for an SA44B or SA124B?
Regards,
A.J.
JaredParticipantHi AJ,
The connection issues are on the SA44B. Typically both difficulty in connecting and connection dropouts. Though today, they haven’t occurred yet… which is odd.
We are trying to reduce current consumption and one of the largest contributors is the products receiver open time.
If we can capture the trigger Tx (up to four randomised re-try events over ~8sec) and the receiving unit’s ACK we can ascertain the minimum and maximum window times. So for me, a 10 second capture would be sufficient.
Oh and the other useful thing would be a real-time button under the Full Span and Zero Span buttons.
Thanks
AndrewModeratorHi Jared,
Regarding the connection issues. What is your current PC power options setting? (Press Windows Key -> Type “Power Options”) We do recommend high performance and for many customers with similar issues, changing this resolves the issue.
As for your measurement requirement, I think the additions to zero-span will be able to satisfy your requirement. 10 second triggerd captures will be possible as well as playing back the file and triggering on events within the capture. I don’t have a time frame on this yet, but it should be in the next release.

JaredParticipantI tried a bunch of things when it was disconnecting and nothing appeared to help. Yet it seems stable now… I don’t know… and I go to investigate the current behaviour for my last point, only to find its all crashed.
Okay that zero span fix sounds like it will do the trick. I’ll wait patiently…
In R/T mode especially, can a preferences setting be that the freq change up/down arrows increment centre frequency by the current span?? Seems to be 20MHz (in all modes) at the moment. Maybe a drop down with 20M, 10M, 1M, Span, 1/2Span, userval?
AndrewModeratorHi Jared,
I apologize if you already knew this, but you didn’t mention it in your message. The frequency up/down arrows adjust the center frequency by the “step” amount, which you can enter a few boxes down.
If you continue to have connection issues, email Justin at justin at signalhound dot com and point him to this thread as well. The SA44B disconnecting in this way is rare, if general troubleshooting does not solve the problem we might suggest an RMA (for us to reproduce the issue in our shop), or ship you a new cable. If you are able to reproduce the issue on another PC, we would be interested to know.
