Prodigy PGY-SMBus is electrical validation and protocol decode software that runs inside a Tektronix oscilloscope. It measures SMBCLK and SMBDAT timing and voltage levels against version 3.2 of the SMBus specification at 100 kHz, 400 kHz and 1 MHz, with limit comparison, and decodes the bus traffic, linking every packet to its waveform. Saved captures from Tektronix, LeCroy and Keysight oscilloscopes can be analyzed offline. Pertech is the authorized Prodigy distributor.
SMBus software highlights
- Automated electrical measurements per SMBus specification version 3.2
- 100 kHz, 400 kHz and 1 MHz bus speeds, with limit comparison
- Protocol data overlaid on the waveform, color-coded by SMBCLK, SMBDAT, address, data and ACK
- Decoded packets linked to the electrical waveform, with a zoomed detail view of any selected frame
- Data shown in hexadecimal, decimal, binary, octal or ASCII
- Search to find a specific event among thousands of packets
- PDF reports with configuration, measurements, images and protocol listing; CSV and TXT export
- Offline analysis of .wfm (Tektronix), .trc (LeCroy) and .h5 (Keysight) files
Electrical measurements
PGY-SMBus covers timing and voltage parameters, including:
- SMBCLK frequency, high and low period
- Rise and fall time of SMBCLK and SMBDAT, and SMBDAT input and output rise, fall, setup and hold times
- Setup and hold time of (repeated) START, setup time for STOP, data valid time and bus free time
- Input low and high voltage (VIL, VIH), output low voltage (VOL), overshoot and undershoot
Where the SMBus software earns its keep
- Validating platform management buses on server and PC motherboards
- Smart battery and power management device compliance checks
- Comparing SMBus captures from different oscilloscope brands in one tool
- Documenting compliance with PDF reports for design reviews

Frequently asked questions
Which SMBus speeds does the software validate?
It measures and decodes SMBus at 100 kHz, 400 kHz and 1 MHz, comparing each measurement against the limits in SMBus specification version 3.2.
Which oscilloscopes does PGY-SMBus run on?
It runs inside Windows-based Tektronix oscilloscopes, and uses the digital channels of an MSO for decoding where available.
Can it analyze captures from other oscilloscope brands?
Yes, offline: besides Tektronix .wfm files it reads LeCroy .trc and Keysight .h5 files.
Do I also need an SMBus exerciser?
The software analyzes what the oscilloscope captures; it does not drive the bus. To emulate an SMBus device, generate traffic or inject errors, pair it with Prodigy’s SMBus Protocol Exerciser and Analyzer.
Where can I buy Prodigy SMBus software in Israel?
