The NSI 8720 Antenna Measurement System uses the Agilent
8720ES Vector Network Analyzer (VNA) for automated antenna pattern
measurements. It operates from 50 MHz to 20 GHz and includes an internal
synthesizer, tuned receiver, and GPIB interface to the NSI measurement
workstation. For antenna measurements, the S-parameter test set is replaced
by a direct sampler (option 012). Options are available for extending the
frequency range to 40 GHz with the Agilent
8722ES. Lower cost options are also available with lower frequency
range. The NSI 8720 is an ideal choice for cost- and space-conscious engineers
in research and development, manufacturing, incoming inspection, or quality
assurance. The NSI 8720 RF system includes the Agilent 8720ES, system cabling,
components and documentation.
System Description The NSI 8720 antenna measurement system provides the instrumentation for either automated far-field antenna pattern or radar cross-section measurements. It uses an internal synthesized sweeper and a tuned receiver to provide amplitude and phase measurements. The direct sampler option (012) is used to bypass the S-parameter test set for improved system sensitivity. Option 012 adds RF loops that provide direct access to the A and B samplers in the port 1 and port 2 receivers. This allows for transmission measurements that bypass the receiver coupler for a 16 dB improvement in sensitivity. High source power and excellent receiver sensitivity combine to give the Agilent 8720ES a dynamic range of 100 dB. Receiver speed is approximately 1200 measurement points per second. The Agilent 8722ES is available as an option to extend operation to 40 GHz. Options are available for lower frequency operation, AUT and probe PIN switches. The NSI 8720 is compatible with NSI antenna measurement software. Key Specifications:

Facility Requirements The following tables provide information on size, weight, power, and air conditioning requirements for commonly used NSI and Agilent products to aid in preparing your site for an RF Subsystem. Items shown are for planning purposes only, your system configuration may vary. Make sure your installation meets local building, electrical and fire codes, as well as any insurance regulations. Size and Weight
Power and Cooling Install adequate AC power at all necessary locations. All equipment
operates on 110 VAC, 60 Hz facility power, unless otherwise specified.
A 20A outlet is required for the equipment rack. Contact NSI for special
facility accommodations. Make sure enough outlets are provided at each
location, and that they can supply the required amount of current. Place
air conditioning equipment, compressors and large power converters on a
different AC circuit than that used for the RF subsystem equipment.
