D9010LSSP Low Speed Serial Protocol Trigger and Decode

The D9010LSSP software package for Infiniium oscilloscopes gives you the ability to trigger and decode on a large and ever-expanding suite of low-speed serial protocols: I2C, SPI, eSPI, Quad SPI, Quad eSPI, RS232/UART, JTAG, I2S, SVID, and Manchester. This package applies to the Keysight EXR, MXR, S, V, and UXR Series Infiniium Oscilloscopes.

Lower-speed serial bus interfaces are widely used today in electronic designs for chip-to-chip communication. In many designs, these serial buses tend to provide content-rich points for debugging and testing. Extend your scope capability with the D9010LSSP low-speed serial protocol triggering and decoding application! This application makes it easy to debug and test designs that include low-speed serial protocols using Infiniium oscilloscopes. Get access to a rich set of integrated protocol-level triggers specific to each serial bus. When serial triggering is selected, the application enables special real-time triggering hardware inside the scope.

Hardware-based triggering ensures that the scope never misses a trigger event when armed. This hardware takes signals acquired using either scope or digital channels and reconstructs protocol frames. It then inspects these protocol frames against specified protocol-level trigger conditions and triggers when the condition is met.

• Easy access to set up with a dedicated Serial Decode front panel key.
• Setup your scope to show protocol decode in less than 30 seconds with an auto-setup key for every protocol that sets threshold levels, baud rates, sample rate, memory depth, and more.
• Save time and eliminate errors by viewing packets at the protocol level on the physical waveform, or in tabular or graphical format.
• Easy-to-use search and navigate tools allow you to search through long sets of data and find specific packets of interest on the serial bus.
• Segmented memory allows you to capture seconds to days’ worth of serial protocol traffic. The scope fills memory in segments as each acquisition sees a trigger condition, using time tags to track time between segments

D9010LSSP provides a fast and easy way to debug the Inter-Integrated Circuit (I2C) serial communication busses found in a wide variety of embedded designs. It provides protocol-level debug information for Keysight’s Infiniium series oscilloscopes. With new, enhanced serial analysis capabilities, D9010LSSP provides not only decode, but also listing window view, software searching, and trigger on search. When serial triggering is selected, the application enables special real-time triggering hardware to ensure that the scope never misses a trigger when armed.

SPI

D9010LSSP provides a fast and easy way to debug 2-wire, 3-wire, or 4-wire Serial Peripheral Interface (SPI) serial communication busses found in a wide variety of embedded designs. It provides protocol-level debug information to Keysight’s Infiniium series oscilloscopes. With new, enhanced serial analysis capabilities, D9010LSSP provides not only decode, but also listing window view, software searching, and trigger on search. When serial triggering is selected, the application enables special real-time triggering hardware to ensure that the scope never misses a trigger when armed

Quad SPI

Quad-SPI is a serial interface allowing communication on four lines between a host and external Quad-SPI memory. The Quad-SPI protocol supports traditional SPI as well as the dual-SPI mode which allows it to communicate on two lines. Quad-SPI uses up to six lines in quad mode: one line for chip select, one line for clock, and four lines for data in and data out.

Like all other low-speed protocols on Infiniium, you will be able to set specific triggers, decodes, save and export data, run search queries, and view data in the lister. There is also an auto setup and symbolic decoding available.

eSPI

Enhanced Serial Peripheral Interface (eSPI) is developed by Intel as a successor to its Low Pin Count (LPC) bus. So it can carry out not only legacy SPI data but also Embedded Controller (EC), Baseboard Management Controller (BMC), and Super-I/O. This standard allows designers to use 1-bit, 2-bit, or 4-bit communications at speeds from 20 to 66 MHz to further allow designers to trade off performance and cost. Extend your oscilloscope’s capability with Keysight’s eSPI triggering and decode application. It makes it easy to debug and test designs that include eSPI protocols using your Infiniium oscilloscope. Quad I/O decode is only available on MSO models

RS232 / UART

D9010LSSP includes a suite of configurable protocol-level trigger conditions specific to RS-232 and other UART interfaces. When serial triggering is selected, the application enables special real-time triggering hardware to ensure that the scope never misses a trigger when armed.

The protocol viewer includes correlation between the waveforms and the selected packet, enabling you to quickly move between the physical and protocol layer information using the time-correlated tracking marker.

JTAG

While oscilloscopes have long been used to debug JTAG (IEEE 1149.1) signal integrity issues, Keysight’s Infiniium Series is the first oscilloscope family to support JTAG protocol decode. While the need to decode JTAG may be infrequent, the difficult process of manually decoding JTAG TAP controller states, including instruction and data register values, is time-consuming and error-prone. D9010LSSP provides real-time, at-speed, JTAG decode from TMS, TDI, TDO, and TCK signals acquired on either scope or digital (MSO) channels. This application imports device names and opcodes from industry-standard BSDL files, displays JTAG protocol in real-time, and flags certain types of error conditions. Signals must be probed at the periphery of the scan chain and cannot be probed in the middle of the scan chain.

The multi-tab protocol viewer includes search capabilities and correlation between the waveforms and the selected packet, enabling you to quickly move between the physical and protocol layer information using the time-correlated tracking marker.
