What is the display format of a logic analyzer?

Logic analyzer is a commonly used analytical instrument. After the measured data signal is written into the memory in digital form, all or part of the data in the memory can be stably displayed on the screen through the control circuit as needed. Do users know the display forms of logic analyzers? The following editor will specifically introduce the four display forms of logic analyzers, hoping to help everyone.

Timing display

Timing display is to display the contents of the memory on the screen in the form of a waveform diagram represented by logic levels. What is displayed is a series of waveforms similar to square waves after shaping. The high level represents "1" and the low level represents "0". Since the displayed waveform is not the actual waveform, it is also called "pseudo waveform".

Status table display

The status table displays the contents of the memory on the screen in various numerical values ​​such as binary, octal, decimal, and hexadecimal.

Graphical display

Graphical display is a way of displaying with the X direction of the screen as the time axis and the Y direction as the data axis. The digital quantity to be displayed is converted into analog quantity through a D/A converter, and the analog quantity is displayed on the screen in the order of the digital quantity taken out from the memory to form a dot matrix of an image.

Image Display

Image display is to display all the contents in the memory in the form of dot images at once. It divides each memory word into two parts, high and low, which are converted into analog quantities by X and Y direction D/A converters respectively and sent to the X and Y channels of the display. Then each memory word lights up a dot on the screen.
