Description
The U4164A logic analyzer provides industry’s highest data rate state mode (up to 4 Gb/s), highest deep trace timing mode (up to 10 GHz), and deepest memory (up to 400 Mb), enabling validation and debug of DDR4 or LPDDR4 at data rates over 3.5 Gb/s.
The Keysight U4164A logic analyzer system combines reliable data capture with powerful analysis and validation tools to enable you to quickly and confidently validate and debug high-speed digital designs operating at speeds up to 4 Gb/s. The U4164A logic analyzer module delivers the following unique capabilities that enable you to make measurements and achieve levels of insight unavailable with other logic analyzers
The U4164A logic analyzer module has two modes of operation: quad sample state mode and 10 GHz quarter channel timing mode. Quad sample state mode achieves four different sample positions at two independently adjusted thresholds from a single probe point on each input.
Quad sample state mode means less space is required to probe high data rate signals such as DDR4, DDR5, LPDDR4, and LPDDR5 that require different sample positions for read and write data and separate rising edge / falling edge samples for data rates greater than 2.5 Gb/s. Quarter channel (10 GHz) timing mode provides up to 1.6 Gb samples per input. In addition to the new modes of operation, the U4164A logic analyzer module includes multiple new features to help high-speed digital and DDR / LPDDR memory design engineers accelerate turn-on and debugging their systems.
