N9070A Wideband

Signal Analysis Solution

Introduction

Wideband commercial, satellite or radar signals can now be analyzed with commercial test equipment at a fraction of the cost and measurement time of traditional solutions using the N9070A wideband signal analysis solution. The Keysight Technologies, Inc. N9070A consists of Keysight’s N9030A PXA signal analyzer, combined with an Infiniium DSO9204H oscilloscope and 89600 VSA software, orderable as N9070A-001.

The N9070A takes advantage of the PXA’s wide IF output, the high dynamic range of the Infiniium oscilloscope, and the powerful 89600 VSA to deliver a wideband high-dynamic range signal analysis solution at an affordable price. This solution does not require a stimulus, the correction data is exported from the PXA to the 89600 VSA so the user does not need to do time consuming calibrations for acceptable measurement results. Correction data is quickly loaded when the user changes center frequency and span, and the full analysis capability of the 89600 VSA can then be taken advantage of. The corrections contain both amplitude and phase, which enables the 89600 VSA to make accurate wideband measurements such as analysis of chirp linearity, demodulation of cellular, emerging, or custom modulation formats.

Key Features:

– Automatically loads correction data from the PXA signal analyzer

– PXA correction data for > 1 GHz of bandwidth

– Measurement characteristics including frequency response and phase linearity performance up to 800 MHz of bandwidth

– Includes high dynamic range scope with up to 12 bits of resolution

– Quick setup and measurements

– Frequency coverage to 50 GHz

89600 VSA software

The 89600 VSA software is a comprehensive set of tools for demodulation and vector signal analysis.

– Gain greater insight with high resolution FFT-based spectrum, time and modulation domain analysis

– Capture and playback signals for detailed gap-free analysis

– Vector measurements for RADAR/EW

– Over 75 signal standards and modulation types, including:

– Cellular communications: LTE-Advanced, W-CDMA, HSPA+, GSM/EDGE Evolution, TD-SCDMA, cdma2000®

– Wireless connectivity: WLAN 802.11a/b/g/n/ac, WiMAXTM, Bluetooth®, Zigbee, RFID

– Aerospace, defense, satellite: AM, FM, PM, BPSK, QPSK, QAM, APSK, FSK, VSB, SOQPSK, APCO 25

– Custom modulation: evaluate non-standard or proprietary OFDM and APSK signals

Keysight’s high dynamic range oscilloscopes bring 12-bit digitizer performance, enabling the N9070A to attain results similar to an integrated signal analyzer. Measurements such as error vector magnitude are accurate due to both sets of correction data and the performance of the digitizer. The 89600 VSA can run inside the scope, giving the user a large screen display to view an extensive amount of measurement views.

The N9070A is an easy-to-use solution. Setup is done in a few simple steps and using the integrated software component in the VSA, switching measurement parameters is fast and straightforward. Using an Ethernet cable between the PXA and scope enables the 89600 VSA to load correction data and set up the measurement; the user does not have to interact between the signal analyzer or the scope interface.

The N9070A allows for a flexible measurement capability without sacrificing usability. Bandwidth, center and IF frequencies can be selected by the user and the software automatically loads the appropriate correction data. When signal recording is required, using the N9070A allows for much longer record lengths due to the use of the downconverter. The recorded waveform data can be analyzed using the 89600 VSA or easily exported to MATLAB or other popular formats.
