SP259 Series User Manual SP259 / SP259i
SP259 Series overview
SP259 series logic analyzers and protocol decoders oer in depth analysis of logic signals and protocols
with 250MHz (4ns) timing resolution. 9-channel operation allows 8-bit parallel data to be captured
along with a clock or strobe signal. SP259 series logic analyzers connect to a computer via a USB3
interface to configure the device and to visualize captured data.
SP259 Series is composed of two devices, SP259 and SP259i. Both oer 9 logic inputs, but
SP259i integrates industrial receivers for CAN, LIN, RS232 and RS485 buses.1

Embedded memory
SP259 series logic analyzers feature a 1Gb HyperRAM memory running at 4Gbps and is used to store
compressed samples before streaming to host computer. This embedded memory ensures uninter-
rupted captures of high frequency signals for long period of time without needing any reliance on host
computer performances.
1Industrial receivers in the SP259i are multiplexed with one or more of the existing 9 logic channels

Evolution from older SP209 series
SP259 are meant to replace and superceed older SP209 series of logic analyzers. SP259 devices have
all the features found in older SP209 devices, and have the following enhancements:
New SP259 Series Older SP209 series
250MHz maximum sampling frequency 200MHz maximum sampling frequency
Adjustable sampling frequency Sampling frequency fixed at 200MHz
USB3.0 interface USB2.0 interface
Fine adjustment of Threholds for input frontend Only 3 fixed thresholds
Typical applications
SP259 series logic analyzers are perfectly adapted for demanding applications, where it is needed to
capture logic signals with maximum time resolution on all 9 channels for long periodes of time.
•Embedded systems debugging
•Research and education
•Serial protocols analysis, like I2C, SPI, UART or 1-Wire (non exhaustive list)
•Industrial bus analysis: RS232, RS485, CAN, LIN
•ADC and DAC system diagnostic
