Internal Indicator LEDs
The logic analyzer has two internal indicator LEDs located on the PC Interface
board. These LEDs can be used for troubleshooting:
H Ready Indicator. This LED indicates that the instrument has passed the
power-up diagnostics and is ready to communicate with the acquisition
controller.
H Access Indicator. This LED turns on any time the acquisition controller
accesses the main instrument circuitry.
