Loop Speed

The Loop Speed pane ( Working with Hardware Diagnostic Action editor) configures diagnostic tests for performing repeated memory reads and writes over the remote connection interface. The tests repeat until you stop them. By performing repeated read and write operations, you can use a scope analyzer or logic analyzer to debug the hardware device. After the first 1000 operations, the Status shows the estimated time between operations.

Note: For all values of Speed, the time between operations depends heavily on the processing speed of the host computer.

For Read operations, the Scope Loop test has an additional feature. During the first read operation, the hardware diagnostic tools store the value read from the hardware. For all successive read operations, the hardware diagnostic tools compare the read value to the stored value from the first read operation. If the Scope Loop test determines that the value read from the hardware is not stable, the diagnostic tools report the number of times that the read value differs from the first read value. Following table lists and describes the items in Loop Speed pane.

Table 1. Loop Speed Pane Items
Item Description
Set Loop Sp eed Enter a numeric value between 0 to 1000 in the textbox to adjust the speed. You can also move the slider to adjust the speed at which the hardware diagnostic tools repeat successive read and write operations. Lower speeds increase the delay between successive operations. Higher speeds decrease the delay between successive operations.
