DSRemote 0.31
-------------
This is the first version that is using a separate thread for the communication with the oscilloscope.
This is done to keep the graphical user interface smooth and responsive.
When opening a connection, the program reads the settings from the device.
It does not lock the device, so it's still possible to change settings on the device.
This will cause a mismatch between the programs settings and the device settings.
This can be solved by letting the program re-read the settings of the device.
Either, disconnect and connect again, or click on the "Factory" setting in the "Save" menu of the program.
Some settings are checked regularly and will always be synchronized:
- trigger status
- trigger sweep
- samplerate
- memory depth
There are some peculiarities when testing with the DS6104 and the DS1054Z:
DS6104: (software version 00.02.00.SP5, hardware version 1.8)
=======
USB connection: full speed (12MBit)
Reading screen data is pretty fast, 20 waveforms per second is easily possible.
Reading a screenshot in BMP format is slow, approx. 3 seconds.
You need to add an udev rule. See readme_usbtmc_driver.txt for how to do that.
DS1054Z: (softversion 00.04.04.SP1, boardversion 0.1.1)
========
USB connection: high speed (480 Mbit)
Reading screen data is slow, maximum 4 waveforms per second with one channel.
With all four channels active, downloading the screen waveform data is really slow.
Reading a screenshot in BMP format is faster, less than one second.
It's plug and play, no need to add an udev rule.
How to operate:
---------------
Use the mousewheel to change the dials. In order to simulate a push on a dial,
click on it with the right mouse button.
To toggle the delayed timebase, right-click on the timebase dial.
To set the horizontal position to zero, right-click on the horizontal position dial.
To set the vertical offset to zero, right-click on the vertical position dial.
In addition of using the dials to change the scale and offset of the traces and
the trigger position,you can use the mouse to drag the colored arrows aside of the plot.
Keyboard shortcuts:
-------------------
PageUp: move traces 12 (or 14) divisions to the right.
PageDn: move traces 12 (or 14) divisions to the left.
Arrow left: move traces 1 division to the right.
Arrow right: move traces 1 division to the left.
Arrow up: move active trace 1 division up.
Arrow down: move active trace 1 division down.
Zoom In (decrease timebase): Ctl+
Zoom Out (increase timebase): Ctl-
Increase vertical scale: -
Decrease vertical scale: +
Press '1' to select or deselect channel 1.
Press '2' to select or deselect channel 2, etc.
Press 'c' to center the horizontal position.
Press 't' to center the trigger position
Press 'f' to toggle FFT.
What's implemented so far:
--------------------------
- horizontal timebase
- horizontal offset
- horizontal timebase delay on/off
- horizontal vernier
- vertical sensitivity
- vertical offset
- vertical bandwith limit
- vertical coupling (ac/dc/gnd)
- vertical display channel on/off
- vertical vernier
- vertical invert
- basic trigger settings like:
- run/stop, single, auto
- trigger holdoff
- trigger source (chan1/4, ext, ext5, ac)
- trigger edge (positive, negative, rising edge & falling edge)
- trigger level
- trigger level 50% (DS6000 series only)
- trigger force
- measure hardware frequency counter
- display clear
- display grid
- display grading
- display vectors
- display dots
- acquire normal
- acquire average
- acquire peak detect
- acquire high resolution
- acquire memory depth
- save screenshot
- save display data
- save memory data (via the Wave Inspector)
fileformat for waveform data is EDF, these files can be read by lots
of viewers and analyzing software like EDFbrowser, Scilab, Octave, Matlab, Labview, etc.
- Set to factory settings
- FFT
The sample data used to do the FFT, is used from the trace, not the deep memory data.
It's not possible to remotely do an FFT with the deep memory data in "real time".
Due to a bug in the firmware of the scope, the parameters "Center" and "Hz/Div" are not updated
correctly on the scope itself when you change the horizontal timebase.
A workaround is to disable and enable the FFT again.
- Wave Inspector
The wave Inspector allows you to download the whole waveform memory (up to 24Mpts for the DS1054Z,
depending to the acquire memory depth setting) after which it will be displayed in a separate window.
Once the Wave Inspector has been opened, you can quickly and comfortable navigate through the waveform
using the above described keyboard shortcuts or the slider at the bottom of the screen.
- Serial Decoder
This is a work in progress. So far, only UART and SPI are implemented.
Stay tuned for updates.
- Record & Replay (it's hidden under the "util" button)
