Multiband Vector Transceivers Wideband RF transceiver testing

Options up to 4 Gb/s State Mode and 10 GHz Timing Mode

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. The U4164A features a timing mode de-skew control, dual thresholds in dual sample state mode, clock hysteresis control to adjust the state mode sensitivity to noise, and the industry's deepest memory depth option (400 Mb full channel, 800 Mb half-channel, and 1.6 Gb in quarter-channel).

To enhance insight from the U4164A trace captures, the B4661A Memory Analysis software offers tools to accelerate setup and configurations for DDR / 2 / 3 / 4 / 5 and LPDDR / 1/ 2 / 3 / 4 / 5 measurements and a variety of licensed options for DDR / 2 / 3 / 4 / 5, LPDDR / 1 / 2 / 3 / 4 / 5 and ONFi (Open NAND Flash interface) memory analysis and accomplice validation.

Applications: High-volume test of 5G NR network equipment and radio components

• 5G NR base station transceiver systems
• 5G NR components, including remote radio heads (RRH), distributed units (DU), active antenna arrays, amplifiers, chipsets
• Power, SEM, ACLR, EVM and more measurements using familiar and industry proven application software (N9085EM0E 5G NR Measurement Application)

Benefits

• Lower Cost of Test with reduced footprint vs. benchtop instruments and extremely high test-throughput (“cloud ready”)
• OTA readiness saves space and cost with single bi-directional remote heads, with in-head switching for 2 polarizations, across all 22.7 GHz to 49.2 GHz bands, delivering best Power and EVM at chamber
• Manufacturing Effectiveness: 1.2 GHz BW across the entire frequency range for Tx/Rx with low EVM and ACLR, operates as single instrument (includes: switching, heads, API, measurements), easy automation with calibrated system accuracy that reduces rework and false verdicts
• Minimize test development time by reusing existing code from other Keysight non-signaling solutions like E6681A, S9110A and S9101A
• Supports both FR1 and FR2 measurements in the same system without the need to re-cable the test setup

Functionality

• Wideband signal generation and analysis of 5G NR (3GPP Release 15 and higher) waveforms in both: FR1 (380 MHz to 13 GHz) and FR2 (22.7 GHz to 49.2 GHz)
• Features “OTA-friendly” expandable architecture: avoid high losses from switching and long cable runs, supports one or two remote mmWave heads and polarizations, and multiple Tx/Rx channels

Measurement applications and software

• The S9115A system includes Keysight N9085EM0E 5G NR Measurement Application, Y9085EM0E 5G NR Non-Signaling Waveform and Measurement Application.
• Additional recommended software: N7631C Signal Studio Pro for 5G NR, N7630C for pre-5G, N7608C for custom IQ and OFDM, 89600 VSA software, and KS8400A Test Automation Platform

The Keysight S9115A 5G Multi-Band Vector Transceiver with one or two transceivers covers FR1 (380 MHz to 13 GHz) along with one or two mmWave transceivers that covers FR2 (22.7 GHz to 49.2 GHz).
