SPI Electrical Validation and Protocol Decode Software

The PGY-SPI Electrical measurements and Protocol Decode Software offers electrical measurements and protocol decoding for SPI buses. This software provides the flexibility to set reference levels for electrical measurement and customized limits making it the most versatile solution to meet different needs of characterizing SPI Signals. Now design and test engineers can automatically make accurate and reliable electrical measurements and decode protocols in PGY-SPI software using data acquired by Tektronix DPO5000, TDS7000, DPO/DSA/MSO7000 oscilloscope series to reduce the development and test cycle.

Seamless Integration with Oscilloscope

PGY-SPI Software runs inside the Tektronix oscilloscopes and makes the electrical measurements, decodes protocols and displays the decoded data in a table, and links the decoded data to the electrical signal in the waveform plot. SPI Protocol-based trigger can be set up using the built-in SPI trigger capabilities in Tektronix oscilloscopes.

Reference Level Setup

There are no standard measurement limits defined for SPI Bus for pass/fail tests. The limits are varying in nature depending on the SPI Bus speed. In order to characterize and validate SPI signals PGYSPI software provides a graphical measurement reference level setup to set the measurement reference level of SPI signals. These limits are automatically applied while making selected SPI measurements in PGY-SPI software and reduce test time by offering reliable measurements.
