Theremino SignalScope: Realtime Slot visualization.

When the simple viewer of http://www.theremino.com/downloads/foundations is not enough you can use this Signal Scope.

Attention: This is not an oscilloscope, but a Slot Signals Viewer. They have a maximum resolution of a millisecond and then a maximum bandwidth (theoretical) by 500 Hz. In practice, however, the phenomenon of aliasing limit the range of frequencies to 100 Hz or so. If you want a true oscilloscope with 22 KHz of bandwidth and 192 KHz sampling download “Theremino DAA” from this page.

Features:

• Storage of signals of two slots for the last 30 minutes maximum resolution.
• Ability to scroll backward signals (Delta time) to locate and zoom in on particular events.
• Two adjustable sliders with the mouse to measure widths, times and frequencies.
• Both the sliders that the delta time can be adjusted with the mouse and also with the TouchScreen.
• Continuous display of instantaneous values and peak-to-peak in the status bar.
• Ability to save and restore the event buffer.
• Ability to save images for documentation.
• Storing all functions and restore on reboot.
• Possibility to program the stop sampling after a number of events have occurred, by setting a threshold value and a counter.

Scope of Signal Features of version 2.2 onwards:

• Number of channels to be increased 2 to 4.
• The individual channels have a box to enable.
• Ability to duplicate the executable in the same folder Theremino_SignalScope1.exe / Theremino_SignalScope2.exe ecc.. , in this case each application will use its own initialization file, and then remember and will restore its configuration at startup.
• The new box “Clear buffer” It allows you to clear the buffer for each new acquisition, or to append new data to the existing buffer.
• New box “Run Slot” to start the RUN with the value of a slot (Zero = firm / Any other number = start).
• the adjustment “Stop delay” which delays the end of the acquisition, after that “Run slot” is back to zero (in some cases it is useful to capture the final events of the several).
• New automation to save the data buffer and the image when the value of a slot exceeds the 500 (the numbers of slots to be used are adjusted in the top two boxes, Right written “save slot”)

Scope of Signal Features of version 2.4 onwards:

• Buffer length adjustment from 1 to 60 minutes. This is a great improvement that allows you to see back in time as much as necessary without creating files that are too large and without slowing down the startup and closing of the application too much. Normally seeing back for a few minutes is more than enough, but if necessary you can stretch the buffer up to an hour. However don't set it too short, Go below the 5 minutes is of little use and keep in mind that the data files that are loaded and saved are truncated to the length of the current buffer.
• The DeltaTime is highlighted in orange and to reset it just double-click on the box.
• Ability to coexist multiple applications with SignalScope1.exe names, SignalScope2.exe, etc.. in the same folder. Each application uses a separate initialization file and will save data in separate Buffers and Images folders.
• Added date and time up to milliseconds in the display at each start of data logging.
• Fixed several minor bugs and improved general operation.

Scope of Signal Features of version 2.5 and 2.6 onwards:

• The SlotNames file is automatically reloaded when other applications modify it.
• By adjusting the Buffer (min) to zero, the Buffer is emptied at each new RUN

cope of Signal Features of version 2.5 and 2.6 onwards:

• The SlotNames file is automatically reloaded when other applications modify it.
• By adjusting the Buffer (min) to zero, the Buffer is emptied at each new RUN

Recommendations:

• Enable “Trigger” only for fast repetitive signals, otherwise the display is very slow.
• Keep “Delta Time” zero if not in use, otherwise the signals do not appear immediately but only after the milliseconds set. Double clicking on the DeltaTime box resets it.
• Keep “Stop If” disabled if not in use, otherwise, sampling could stop unintentionally.
• Edit the file “Slot names” to give a meaningful name to its Slot.
• Copy the executable executable ’ ’ this application next to dell ’ HAL and Viewer share the same Slot “Slot Names”.
• Disable “Interpolate” quick on/off signal, that would otherwise be distorted.
• Adjust the buffer length to no more than ten minutes in order not to slow down the startup and closing of the application and not to create files that are too large.

Notes for versions

Version 1.2: This is the first published version.

Version 1.3: When the slot names Panel is visible only if space allows.

Version 1.4: The parameter “Delta” is reset each time you press “RUN” so you don't forget.

Version 1.5: Deleted the error in closing if the folder was missing “Buffers”.

Version 1.6: Deleted the error in closing if the RUN time was greater than the length of the buffer that stores the data. Extended storage buffer 24 hours. Beware that with very long buffer time to save loading can be quite long.

Version 1.7: If cursors are enabled then is saved only the area between the two sliders. The Trigger is greatly improved. Deletes a waveform instability happening randomly. The buffer is again limited to 1 now (for log Logger applications are used). Save and load buffer takes at most 2 seconds. The DeltaTime be changed quickly using CTRL and SHIFT + Mouse.

Version 1.8: Deleted error with very large input values.

Version 1.9: Added ability to disable interpolation that in some cases distorted signals. Deleted mistake by starting the application minimized.

Version 2.0: Fix error that occurred with Min = 0 and Max = 0.

Version 2.1: When starting the application, the Slot box is cleared. This eliminates the need to change its value by mistake, using the keyboard arrows. LATEST VERSION 2 CHANNELS

Version 2.2

– Number of channels to be increased 2 to 4.

– The individual channels have a box to enable.

– The new box “Clear buffer” It allows you to clear the buffer for each new acquisition, or to append new data to the existing buffer.

– Ability to use multiple copies of the same folder SignalScope, with names or Theremino_SignalScope1.exe 2 or 3,

in this case each application will use its own initialization file, and then will remember its configuration.

– New automation to start the RUN with the value of a slot (Zero = firm / Any other number = start)

– New automation to save the data buffer and image with the value of a slot (It acts surpassing the value 500)

Version 2.3

– Improved operation of the button “Clear buffer”

– The main window is brought to the foreground at any “Run” controlled by a Slot

Version 2.4

– Boxes Min, Max and Center which also accept numbers with decimals.

– The LastBuffer.csv file is created with a prefix that also contains the application number.

– The DeltaTime is highlighted in orange to avoid forgetting it active.

– Double clicking on the DeltaTime box resets the time.

– Fixed the defects of the StopDelay that sometimes did not work.

– The Buffers and Images folder change names if multiple SignalScopes are used (SgnalScope1.exe, SignalScope2.exe ecc…)

– At each new start of the acquisition the date is also shown, now, minutes, seconds and milliseconds.

– Now you can adjust the buffer length from 1 minute to 1 now.

Version 2.5

This version automatically reloads the file “SlotNames.txt” when modified by an external application (usually HAL, SlotViewer o Notepad).

Version 2.6

– We fixed a small bug in CSV files

– By setting the Buffer(min) to zero, the buffer is emptied at each new RUN

Version 2.7

– In previous versions there was an error that made it difficult to adjust the CenterPosition

Version 2.8

– New button “Time” in the top bar to delete vertical divisions over time.

– Units/div boxes. up to 5000000
