Controlling the PGA450-Q1 Memory Spaces With the GUI

Figure 8. Echo Data Stored in FIFO RAM Plotted in Excel

10.7.2 EVAL Monitor

This tab graphs the output of the digital data path directly in the GUI. The 8051W microcontroller must be

in reset to use this tab.

10.7.2.1 No. of Loops

This option selects how many times the GUI will transmit a burst and plot the echo data.

10.7.2.2 Trigger

If "Auto" is displayed, the GUI will continue sending bursts and plotting the echo data until the "Loops

Complete" count matches the "No. of Loops." If "USER" is displayed, the GUI will stop and wait for the

user to press the green flashing "Trigger" button before continuing.

10.7.2.3 Resolution

This button has three options, "FULL", "1/2", and "1/4". The "FULL" setting plots all of the echo data

points, but takes more time. The "1/2" and "1/4" options reduce the number of data points plotted which

results in faster plotting.

10.7.2.4 Clear Plot

The "CLR" button clears all data from the graph. If the "Clear Plot" option is checked, echo data will be

cleared from the plot every loop. If "Clear Plot" is not checked, every loop will plot the new echo data in a

new color on top of the existing data on the graph.
