SPI Electrical Validation

Use an oscilloscope for SPI electrical validation to ensure compliance with defined specifications. After an extended burn-in test, the oscilloscope confirms that the electrical characteristics of the signal meet the required standards.

Supported Models:

TS3124V (4-channel DSO)

SPI Electrical Validation Settings:

1. General Settings: Channel sources, working voltage and speed

2. Decode Settings:In the Decode Settings, it requires you to setup the SPI data format and the Latching Edge of each channel. The SPI data format set here is applied both to the Decode and Trigger Settings.

3. Trigger Settings: Setup the data address and which data pin to trigger.

4. Electrical Validation Parameter Settings: Frequency, Timing, Voltage limitation

There are no standard measurement limits defined for SPI bus. Therefore, it is recommended to

define your own limits while validate SPI signals.

This section displays 3 characteristics table, including

• Frequency
