Advantest R3131

The R3131 is an excellent operability, usability and easy-to-use personal spectrum analyzer which combines high accuracy necessary for digital radio measurement

The R3131 can be used in diverse fields, for a multitude of applications.

The R3131 searches for the signal with the maximum level within the 3 GHz band and sets the center frequency automatically.

The R3131 then, reproduces the setting which existed immediately before execution of AUTO TUNE, allowing observation under the same measurement conditions.

The R3131 performs frequency measurement with the built-in frequency counter simply by moving the marker to the signal.

The R3131 can measure the power within the specified band of frequency diffuse signals and the total power of multi-carrier signals.

The R3131 can also be used to measure the occupied frequency bandwidth (OBW) and adjacent channel leakage power (ACP) which are essential to transmission characteristics testing for radio equipment.

The R3131 allows you to measure the total power within the window and display it as the channel power simply by setting the measurement window to the specified occupied bandwidth.

The total power from the spectrum displayed on the screen can be obtained by R3131. This function is useful for total power measurement of multi-carrier signals.

The R3131 measures the frequency band which contains 99% of the total power of the spectrum displayed on the screen. In addition, the % value of OBW can be set to any desired value.

The measurement results can be displayed in graphical form, including upper and lower point data, up to the 2nd ACP, respectively, offset from the carrier and leakage power value at all the displayed frequency points.

The R3131 Spectrum Analyzer has the performance of a standard middle class spectrum analyzer and a low cost, the spectrum analyzer can be used in a wide range for many applications.

There is basically designed with a panel size assuming rack mount use.

The operation key layout is a simple, easy to use design which accommodates system use and personal use.

The R3131 allows spectrum analysis of the burst signal by supplying a trigger signal synchronizing with the burst transmission.

The R3131 allows you to store and recall measured waveform data and measurement conditions. The R3131 unit offers up to 10 dedicated files for storage. In addition, the built-in standard floppy disk drive allows, you to store them on MSDOS formatted floppy disks.

The R3131 has shortened the time necessary for GPIB control and data transmission by half or more in comparison with former products. In addition, by reducing the settling time of the local oscillator, the waveform update rate in unit time has been doubled.
