N9075A Mobile WiMAX™ Measurement Application

The N9075A is discontinued after June 1, 2019. The replacement model is the N9075EM0D X-Series Measurement Application with KeysightCare.

Signal analysis

• 802.16 OFDMA measurement per IEEE 802.16 2005 standard
• Base station and mobile station RF transmitter measurements; analog baseband measurements with PXA BBIQ or MXA BBIQ hardware 
• One-button, standard-based measurements including time gated power measurements (channel power, ACP, and SEM) with pass/fail tests
• Runs inside PXA, MXA, and EXA signal analyzers and VXT PXIe vector transceivers

Measurements

• RCE (EVM), RSSI, preamble PCINR, subcarrier flatness, IQ metrics
• Single input analysis of matrix A and pilot-based analysis of matrix B (MIMO) signals
• Time-gated power measurements: SEM, ACP, channel power, spurious emissions
• Delivers relative constellation error (RCE) in multiple levels (composite, pilot, data burst, un-modulated, and preamble)

Performance (hardware dependent)

• RCE (EVM) floor: up to –54 dB (nominal)
• Power accuracy: up to ±0.19 dB
• Analysis bandwidth: PXA, MXA, VXT up to 160 MHz; EXA up to 40 MHz

Other features

• License key upgradeable
• Fixed and transportable license available
• SCPI remote user interface

The 802.16 OFDMA (Mobile WiMAX™) measurement application is one of more than 25 measurement applications in the Keysight X-Series, an evolutionary approach to signal analysis that spans instrumentation, measurements, and software. Transforming the X-Series signal analyzers into standards-based transmitter testers, the application provides fast one-button RF conformance measurements to help you design, evaluate, and manufacture your OFDMA base station and mobile station devices. The measurement offers standard-based pass/fail testing of IEEE 802.16-2005 compliant signals, SCPI programmability, familiar front panel local operation, and superior measurement speed.

RF transmitter measurements

• View comprehensive physical layer characteristics with modulation quality results such as RCE (EVM), spectral flatness, preamble power, and PCINR
• Constellation, symbol error traces, and zone definition map color-coded by data burst simplify design verification and troubleshooting
• Automatic DL-MAP/UL-MAP detection and decoding minimize user setup time and accelerate time to insight
• Accurate power results with time-gated measurements such as ACP, channel power, and SEM
