Tektronix has introduced its first triggering and analysis module targeted specifically at digital audio serial buses for its MSO/DPO4000 series and DPO3000 series oscilloscopes.
With an eye on the Embedded World exhibition, which starts next week in Germany, Tektronix has described how the DPOxAUDIO module can support digital audio design in products ranging from toys to gaming systems and mobile phones to professional recording consoles.
“Common serial bus protocols used in these designs include I2S, TDM, and others. Designers need tools that can help them decode and debug these buses efficiently,” said Tektronix.
The module decodes the protocol, presenting the waveform and decoded data packets time-aligned on the scope display, and provides the ability to automatically trigger on and then search for specific packet level content.
Another new test module for the scopes is the DPOxPWR analysis module for testing switch-mode power supplies.
According to the supplier, typically switch-mode power supplies require a number of specialised measurements. So the new module is configured with a series of automated measurements to simplify the process.
The DPOxPWR power analysis module automates power measurements including power quality, switching loss, harmonics, safe operating area (SOA), modulation, ripple, and slew rate (di/dt, dv/dt), and simplifies the probe de-skewing steps that precede power measurements.
