Advantest R3261A

The Advantest R3261A analyzer is a wide band, very sensitive receiver.

The Advantest R3261A spectrum analyzer employs a synthesized local oscillator for assuring highly stable spectrum analysis and features wide frequency range from 9 kHz to 2.6 kHz.

The R3261A provides full remote-control GPIB, and the memory card function for saving/recalling data and panel settings. The R3261A contains a tracking generator that facilitates frequency characteristic measurement.

The R3261/3361 Series are the first spectrum analyzers to have a dynamic range display of 120 dB. Since the dynamic range display of conventional displays was small when measuring frequency characteristics of filters or amps which use tracking generators, a single display was impossible. The R3261/3361 Series, however, can measure up to 110 dB in a single sweep.

The field strength can be viewed and read directly after compensating the antenna calibration coefficient and that the QP value based on the CISPR standard can be observed directly.

Whole information needed for spectrum analysis is displayed on the CRT together with signal traces. The digital memory screen realizes a flickerless display. Various marker functions assures accurate and easy reading even in the manual mode.

The two channels of completely independent digital memories enable simultaneous display or two screens.

The user-defined function of R3261A allows the user to pick a desired function and define it on the USER key, which works the same way as the ‘function keys’ on a personal computer. The user can thereby create a customized software menu.

The measurement window function allows the user to focus on only the part being displayed. An optional controller function can be installed into the R3261A. Functions for burst signal measurement are available as an option in the R3261A, to further expand its signal analysis ability, and contribute to the development of the latest technologies.

The R3261A should not be used in a place exposed to directly sunlight or corrosive gas and dust or vibration. A cooling fan is provided on the back panel of the R3261A to prevent abnormal temperature rises in it.

The R3261A is designed with the effect of AC power supply line noise taken into consideration. However, it is recommended that it is used in a place where there is minimum noise. Noise suppressers can be used to avoid noise.
