SmartScope - Debug checklist

In case something happened to your SmartScope, you can send in your SmartScope for repair, or (since you're into electronics anyway) you might try to give it a shot yourself. This document gives you a starting point in pinpointing what might be the problem.

Checking for short-circuits

The first thing to check is whether some power rails might be shorted. This might happen when a component was exposed to excessive currents. Check whether none of the nets in the table below are connected to each other. Make sure you the image below to find out where to probe the nets.

	GND	5V	D3.3V_IO	D3.0V	D1.8V	D1.2V	NEG_1.1V

D3.3V_IO
D3.0V
D1.8V
D1.2V
NEG_1.1V

Verifying supply rail voltages

Next, power the SmartScope and measure all voltages to see whether they're close enough to their expected value. Note: in the app, switch to Digital mode to power the D3.3V_IO net
