The menu items have the following functions:
Illuminate
The illuminate option controls the brightness of the grid on the scope display.
With the grid illuminated, it is a bright green colour.
When the grid is not illuminated, it is a dark green. These colours are the default and may be customised through the Screen Menu options below.
Save Screen Image to File
This allows the plot area to be saved to a Windows Bitmap (.bmp) file. A Save As dialog box appears and prompts the user to provide a filename for the image.
Setup Printer
Allows configuration of a printer that is already installed. Options include paper size and orientation.
Print Screen Image
Sends the plot area of the EasyScope window to the printer.
Print Oscilloscope
Send the whole EasyScope window image to the printer.
Load Background from file
Allows the user to load a bitmap image as the background for the plot area.
Save background to File
Allows the user to save the current background to a file as a bitmap image.
Customise Screen Colours
This brings up a sub-menu (shown below) that allows full customisation of the colours, fonts and backgrounds used. Colours can be reset to the original scheme by selecting "Restore Default Colors".
Save Screen Colors to File
The Customize Screen Colors menu can be used to select the display color theme which can then be saved to file (*.col). Different colors can be used in 'Illuminate' and non Illuminate modes.
Persistence Mode
A variable persistence mode display can be selected using this option. The persistence increment, decrement and colors are selected in the Persistence Mode Setup window. Infinite persistence can be selected by setting the persistence decrement to 0.
Persistence Mode Settings
This window enables the variable persistence mode options to be configured.
The persistence increment can be set to a value of between 1 and 64. Every time a display pixel is activated by the oscilloscope trace the 'persistence value' of that pixel is incremented by the persistence increment value. The maximum 'persistence value' is limited to 127.
The persistence decrement can be set to a value of between 0 and 15. The persistence decrement value is also limited to the persistence increment value - 1. The persistence value of every pixel is decremented by the persistence decrement value after a trigger and trace display event. The minimum 'persistence value' is limited to 0.
Eight different colors can be selected to display a certain persistence value range. The colors for each pixel value range can be changed by clicking on the color box and selecting an alternative color from the color selection menu. The default persistence mode colors can be restored by clicking on the 'Restore Default Colors' button.
Save To CSV Text File
This option exports the ten most recent oscilloscope traces to a comma separated values (.csv) file. Column A contains the most recent trace for Channel A while column B contains the most recent trace for Channel B. Columns S and T contain the oldest trace data for Channel A and Channel B respectively. This can be used with 3rd party programs (for example Microsoft Excel) to manipulate and re-plot the data. The plot below was obtained from Excel using an exported .csv file.
In addition, it is possible to save a scope trace to a .CSV file and use this as the source for the signal generator custom waveform. The data in column A (most recent trace from Channel A) of this file is used by the signal generator.
