Acute announced the PCM decode for its logic analyzer models

Pulse Code Modulation (PCM) is a method for digitizing analog signals, commonly used in digital communication systems and digital video processing. This technology quantizes the amplitude of analog signals into discrete levels at fixed intervals and then uses specific digital encoding (typically binary) to represent each amplitude level.

The PCM bus decode feature is available as a free upgrade across all Logic Analyzer products from Acute Technology Inc.


1. PCM Decode with support for three channels: CLK, DATA, CS.
2. Three different modes available:
     A. PCM A Mode (Capture begins after CS Pulse, with data sampled on the next CLK edge, where the Pulse represents the last bit of a packet).
  B. PCM B Mode (Capture begins at the start of the CS Pulse, with data sampled immediately, where the Pulse represents the first bit of a packet).
     C. PCM Multi Mode (Capture window spans from CS Pulse to the next Pulse).
3. Support for up to 8 channels.
4. Data bit support for 8-bit, 16-bit, 24-bit, and 32-bit.
5. Output in .wav format.
6. Direct software playback support.
7. Display of audio waveform.
