Handheld analyser handles W-CDMA basestations

Compact spectrum analyser is claimed as world's first handheld analyser to support all regulation test items for installation and maintenance of W-CDMA basestations.Anritsu Corporation has announced the launch of its compact MS2720B spectrum analyser series, the world's first handheld analyser to support all regulation test items for installation and maintenance of W-CDMA basestations. The MS2720B series is a small (313 x 211 x 77 mm), lightweight (2.9kg), battery powered spectrum analyser that builds on the success of its predecessor MS2720A with strengthened performance and functions. In addition to supporting measurements up to the microwave band, it can also perform optional modulation analysis of W-CDMA signals and high-accuracy power measurements.

As a result, only one MS2720B unit is needed to support all the W-CDMA basestation registration test items standardised by 3GPP.

Battery operation and compact size make it the ideal solution for basestation construction and maintenance inside buildings, underground spaces etc, where AC power is not easily accessible and space is limited.

Increasing use of 3G mobile phone systems is driving widespread construction and maintenance of W-CDMA basestations.

National agencies regulate the registration tests to ensure that W-CDMA basestations are built and maintained in compliance with the standards set by 3GPP.

Previously, on-site measurements of W-CDMA registration test items required carrying large desktop measuring instruments to basestations inside buildings or underground etc, where space is limited and there is no power for the instrument.

This makes the engineers' work difficult, time-consuming and expensive.

To solve this problem, Anritsu has built on its experience with the previous MS2720A series to release this new compact, battery powered, lightweight MS2720B series supporting all the W-CDMA basestation regulation test items.

It is the ideal solution for W-CDMA base-station registration work in confined, difficult-to-access construction and maintenance sites.

The compact, lightweight, handheld, battery powered MS2720B series of spectrum analysers is targeted at measurements up to the microwave band (13 and 20GHz).

The MS2720 has added options supporting W-CDMA modulation analysis and power measurement plus an external Anritsu PSN50 sensor offers all the functions and performance required for regulation tests of W-CDMA basestations, such as CDP and high-accuracy power measurement using measurement functions for frequency (25ppb accuracy), fifth-order harmonics (12.5GHz and higher), and modulation analysis.

Up to 1000 measured data items are stored in internal memory for download to an external PC, facilitating easy analysis and report creation.

The MS2720 is ideal for registration tests, modulation analysis, and fault diagnosis at construction and maintenance of W-CDMA basestations, measurement of harmonics, spurious and interference waveforms for general radio equipment, and measurement of device RF characteristics.
