Anritsu Company Enhances Signal Analyzers with Analysis Tools to Speed Development and Evaluation of Mobile Phones and Base Stations

New Functions Enhance Analysis Capabilities and Add New Tools to the Engineer's Toolbox

Anritsu Company introduces a software bundle for its MS269xA Signal Analyzers to help engineers improve efficiency during development of mobile phones and cellular base stations, as well as in other R&D applications. These new functions spectrogram, spurious emissions measurements, phase noise measurements, and AM/FM measurements provide critical information during the development process and allow rapid evaluation during the product test cycle.

The spectrogram function provides 3D displays of changes in frequency and power in time for signals up to 125 MHz wide. Ideal for measuring the stability of burst signals and transient interference signals, the spectrogram function allows the user to capture and evaluate the time-changing details of RF signals.

The spurious emissions measurement functionality supports Go/No Go evaluation of spurious vs. standard values, and perfectly complements the MS269xA Signal Analyzer wide dynamic range. With a front end that controls the noise figure and digital IF technology using 16-bit ADC, the MS269xA Signal Analyzers achieve a superior display average noise level (DANL) of -155 dBm/Hz and a third-order intercept (TOI) of  >+22 dBm. The resulting dynamic range satisfies the strict spurious measurement requirements of digital systems, such as W-CDMA mobile phones.

Phase Noise is a key metric for oscillators and other non-linear devices, so Anritsu has added a one-button phase noise measurement as a standard function of the MS269xA. Values are reported for the standard offset values of 100 Hz, 1 kHz, 10 kHz, 100 kHz, and 1 MHz. Additional markers record the phase noise values at arbitrary offsets. The stability of the MS269xA platform ensures that these measurements are fast and accurate.On-board AM and FM measurements allow engineers to measure these legacy standards with extremely high precision. Using one-button tests, the MS269xA handles all the computations needed to determine AM depth and FM deviation.

The MS269xA Signal Analyzers support all popular wireless technologies, including LTE, GSM, GPRS, EDGE, W-CDMA, HSPA, and mobile WiMAX. Three models covering frequency ranges of 50 Hz to 6 GHz (MS2690A), 50 Hz to 13.5 GHz (MS2691A), and 50 Hz to 26.5 GHz (MS2692A) are available in the series, so users can select the instrument that matches their measurement requirements. With a fundamental band that goes to 6 GHz, these high-performance signal analyzers have excellent level and modulation accuracy.

The basic instrument includes a spectrum analyzer for classic swept mode measurements, signal analyzer for high-speed, wideband FFT analysis, and a digitizing function that allows the capture and replay of any signal received by the analyzer. The basic analysis bandwidth is 31.25 MHz, the widest basic analysis bandwidth on the market. The addition of the broadband hardware option increases the analysis bandwidth to 125 MHz. An optional 6 GHz Vector Signal Generator to create a one-box tester that saves time, money, and space on the bench.
