I’ve had a new PCS500AU for two days. I like it but there are a couple of modifications that would make it more useful. When in RUN in oscilloscope mode only part of the trace is visible. I would perfer eliminating the time axis scroll bar or have an option to show the whole scan in the form of an expanded screen. For SINGLE mode the scroll bar is fine. I was looking for an event that didn’t have a good trigger point and more often than not it was in the hidden portion of the screen. I ended up using the transient recorder at its highest speed and was able to just detect the evasive pulse but it would have been better at a faster time/div.
Nice that you mainly like the PCS500 oscilloscope.
Due to the display resolution the wave is expanded horizontally beyond the screen area. The scope should work on 800 x 600 displays also.
Maybe in the future no need to support this resolution.
I’m not talking about the computer screen. The oscilloscope screen only shows part of the trace. When using the scope in free RUN mode this is a handicap because events may happen when they are off the oscilloscope screen. If you change the software to eliminate the time base scroll function for the RUN mode the oscilloscope would be much more useful. The sample interval would stay the same but the number of samples would be less before rewriting the memory.
You are right there may be some data invisible.
This solution is a compromise of showing more detailed data or trying to show all the 4096 samples of data on the screen.
There are now 500 pixels in horizontal direction on the waveform display area. If all the data is tried to be displayed, then only about every tenth sample can be displayed on the screen. Fast spikes may be hidden in between the samples displayed.
The oscilloscope user interface is designed to fit to 800 x 600 display resolution. So it is not possible to widen the waveform display area to display more than 500 data points.
Maybe in the future this can be done…
What I’m suggesting is that you don’t try to fit 4096 data points but rather the first 500 or so that now fit on the screen. When the 500 data points are reached reset the sweep (reset the memory address counter and start over). The free run mode is pretty much useless in its’ present form unless you have a continuous waveform.
