SP259 Series Logic Analyzer

9 channel 250 MSPS logic analyzer & protocol decoder

SP259 series logic analyzers and protocol decoders offer in-depth analysis of logic signals and protocols with 250MHz (4ns) timing resolution. The 9-channel logic analyzer allows 8-bit parallel data to be captured along with a clock or strobe signal.

SP259 series logic analyzers rely on ScanaStudio software (runs Windows, Mac and Linux) to capture, display, analyze and decode signals. Most industry-standard protocols can be interpreted, among which: SPI, I2C, USART, 1-Wire, CAN, LIN, I2C, RS232, RS485, TWI and many more (click for the latest list of supported protocol decoders).

SP259 Logic Analyzer and ScanaStudio workspace

SP259 family overview

SP259 Series is composed of two devices, SP259 and SP259i:

SP259 (Standard)

SP259 Logic Analyzer

  • 9 logic channels
  • Support 1.2V up to 5.0V logic levels (adjustable).
  • 250 MHz sampling rate with 9 channels used
  • 1 Gb internal buffer memory

SP259i (Industrial)

SP259 industrial Logic Analyzer

All standard features + Industrial features:
Logic channels can be multiplexed with dedicated industrial inputs that can be directly connected to:
  • 2 RS232 bus
  • 2 RS485 bus
  • 1 CAN bus
  • 1 LIN bus

Top-notch specs, no compromises

  • 9 logic channels with adjustable thresholds (1.2V, 1.5V, 1.8V 2.5V, 3.3V, 5V)
  • State of the art input stage, with Schmitt triggers that eliminate glitches on slow signals
  • 250 MHz sampling rate, with all 9 channels used, can be reduced by the user to 2.5 MHz.
  • External clock option (state mode), up to 62.5MHz
  • Dedicated trigger-In and trigger-Out interfaces on SMA ports to synchronize with other instruments
  • Samples compression and streaming via USB 3.0.
  • 1Gb HyperRAM memory buffers the data when USB isn’t fast enough.
  • Embedded receivers on industrial version: SP259i (RS232, CAN, LIN, RS485).
  • Guaranteed performances on all hosts.

Powerful trigger options

  • Edge trigger
  • Logic change on one or various channels
  • Trigger on a sequence of timed logic signals
  • Trigger on a protocol word or event (like serial word or I2C address acknowledge)
  • External trigger input
  • Trigger output
  • Dual stage trigger (Ex: Edge trigger, then, Trigger on I2C address).

Typical applications

Designed for performance, SP259 series logic analyzers offer the possibility to capture and analyze 9 channels of logic signals and industrial buses at a rate of 250MHz. This is perfectly adapted for demanding applications, where it is needed to capture logic signals with maximum resolution of 4ns on all 9 channels.

  • Embedded systems development and debugging
  • Research and educational
  • Serial protocols analysis, like I2C, SPI, UART or 1-Wire (non exhaustive list)
  • Industrial bus analysis: RS232, RS485, CAN, LIN
  • ADC (Analog to Digital Converter) and DAC (Digital to Analog Converts) diagnostic
  • IoT systems designing
  • Reverse engineering


  • Capture very long sequences of logic signals (up to 2 Tera samples)
  • ScanaStudio Software lets you view decoded signals in many different levels of abstractions (Packets or detailed bits and bytes)
  • Target very specific events, thanks to a versatile multi-stage trigger system
  • Device performance do not depend on USB connection bandwidth
  • ScanaStudio Software running on Windows, macOS and Linux.
  • ScanaStudio Software is free, intuitive and very easy to use.
  • Synchronize captured samples with other lab instruments via Trigger IN and OUT ports.
  • Premium quality hook-style probes set
