In the field of radio communication which supports the in-creasingly information oriented world,

the role played bymicrowave and quasi-millimetric waveband communicationis increasing year by year.

R3272 is a high-function portable spectrum analyzer whichcan be operated simply to do spectrum analysis of thesemicrowave and quasi-millimetric wavebands.

It has a fre-quency range of 9 kHz to 26,5 GHz (or up to 60 GHz using anexternal mixer), an input range of +30 dBm to -120 dBm,

anamplitude display with a dynamic range of 100 dB and aresolution bandwidth of 300 Hz.

A frequency counter with a 1Hz resolution is also provided.

The R3272 is an ideal spectrui analyzer for wave and www.abb-drive.com spuriousmeasurements in microwave circuits and satellite communica-tion.

Description:

A spectrum analyzer is a broadband, very sensitive receiver.

It operates on the principle of a “super-aberrant receiver”, converting higher frequencies (usually ranging up to tens of gigahertz) into measurable quantities.

The received spectrum is slowly scanned through a series of pre-selected frequencies, which are converted to measurable DC levels (usually on a logarithmic scale) and displayed as such on the Advantest R3272’s CRT.

The CRT displays the received signal strength (y-axis) versus frequency (x-axis).

A Microwave Spectrum Analyzer With MorePortability

The R3272 was designed as an ‘active microwave spectrumanalyzer’,meeting MIL standards for shaking, dropping andshocks, It has a robust, compact design, measuring 178 (H)x350 (W)x420 (D) mm and weighing 16.5 kg. Its lightness andcompactness make it much less ofa burden when transportingit to a relay station or other site.

.User Friendly Panel Settings

Simple operation is another design concept of the R3272. Itemploys a TF’T color LCD display in order to show a variety ofinformation reliably,. The frequently used BW, INPUT ATT andSWEEP TIME setting parameters, as well as the OBW, ACP andHARM measurement finctions which are indispensable whendoing transmitter characteristics tests have been given inde-pendent keys on the front panel. This arrangement allowsdirect operation of these functions.
