Signal Analysis will never be the same again

MS269xA Series Signal Analyzers are the latest high performance signal analyzers for next-generation communication applications. The MS269xA Series Signal Analyzer base units include swept spectrum analysis, FFT signal analysis, and a precision digitizer function. Add options to incorporate a Signal Generator, to turn the instrument into a hassle free, plug and play, one box solution.

The MS269xA Series Signal Analyzers support a standard analysis bandwidth of 31.25 MHz that can be extended to 62.5 MHz /125 MHz with optional hardware. Using a patented calibration process, the multipoint amplitude calibration and the phase calibration result in a level accuracy of ±0.5 dB across a 6 GHz span. No other analyzer on the market can meet that specification! These boxes are superlative in every way -- they measure the widest signals and using the latest technology, make measurements faster than ever before. The modular architecture ensures a box that grows as measurement requirements change.

A series of options enables standards-based modulation analysis, vector signal generation, and BER measurement. The end-user can configure a one-box solution that dramatically reduces cost, footprint, and Total Average Cycle Time (TACT) for device evaluation.

The MS269xA Series Signal Analyzers are accurate enough for the most demanding R&D environment, yet are fast enough for the factory floor! Currently supported applications include GSM, GPRS, EDGE, W-CDMA, mobile WiMAX, and LTE.

The wideband FFT signal analyzer (analysis bandwidth of 31.25 MHz with option for 62.5 MHz /125 MHz) supports high-speed continuous measurements including CCDF, frequency vs. time, spectrum, and power vs. time analysis. The standard digitizing function can capture waveforms and immediately play them out using the optional Signal Generator. An extended digitizer option adds the ability to capture signals up to 20 MHz wide for up to 4 hours.

Ultra-High Speed ACLR Measurement

Averaging is a common technique for obtaining stable measurement results when measuring adjacent channel leakage power ratio (ACLR) and occupied bandwidth (OBW) using a spectrum analyzer. The MS269xA Signal Analyzer supports these measurements at high speed by using a capture function.


Capture Function Requires No Averaging!

[Ex.1] - Measurement using conventional spectrum analyzer The spectrum analyzer requires more time to measure because it must sweep for the number of averaging times.
[Ex.2] - Measurement using signal analyzer

The signal analyzer performs high-speed measurement even at the same number of averaging times by capturing the entire in-band data at one time. (8x high speed).
[Ex.3] - Batch capture measurement using signal analyzer
The signal analyzer performs ultra-high-speed measurement by capturing data once for the measurement time equivalent to the averaging times, eliminating the need for averaging. (65x ultra-high-speed)

* The above measurement time is calculated from the time required for 100 measurements.

Measurement Image

The measurement principle is shown in the image below.

The signal analyzer function cuts the measurement time from 2.6s to 0.04s (65x faster) compared to using a conventional spectrum analyzer.

When the Spectrum Analyzer (Ex. 1) sweep time is 95 µs and number of display points is 1001, the time per display point is about 95 µs. To obtain about the same accuracy for one measurement with the Spectrum Analyzer at the Signal Analyzer (Ex. 2), set Analysis Length to 95 µs. Additionally, set Analysis Length to 1900 µs (95 µs x 20 times) to obtain the accuracy for 20 measurement using the Spectrum Analyzer as shown in Ex. 3.

Advantage of Ultra-High-Speed ACLR Measurement

Amplifier adjustment is laborious work (adjustment ‹ › confirmation) requiring confirmation of various performance items, such as the distortion compensation circuit, current adjustment, and frequency characteristics. As a result, careful ACLR adjustment requires a lot of time.

In particular, amplifiers for high-performance base stations require several performance adjustments. Using the MS269xA cuts the work time by a factor of 10.
