Spectrum Analyzers

The R3261/3361 Series are compact and lightweight spectrum analyzers which use a synthesized technique to cover wide frequency bands: 9 kHz to 2.6 GHz (R3261C/3261CN/3361C/ 3361CN) or 9 kHz to 3.6 GHz (R3261D/3361D). ADVANTEST’s long experience in RF technology and software calibration technology have enabled a total level accuracy of 1 dB. These compact analyzers also offer high performance functions such as a central frequency with a 1 Hz resolution, start/ stop frequency setting and an internal frequency counter with a 1 Hz resolution.

■ Total Level Accuracy of 1 dB (Typ.) 

By adding software calibration technology to ADVANTEST’s long experience in RF technology, the R3261/3361 Series achieves a total level accuracy of 1 dB (typical value). With this technology, highly accurate level measurements are possible without worrying about linearity error due to IF stage log amp or RBW switching. 

■ Choose From 6 Models, Depending Upon Your Application

■ 1 Hz Resolution Synthesizer and Frequency Counter 

Although portable, the R3261/3361 Series uses a synthesized system, so the central and start/stop frequencies can be set with a resolution of 1 Hz. Frequency measurements with a 1 Hz resolution can be done with the internal frequency counter. Spectrum analyzers can not only measure transmitter carrier waves, but can also measure modulated frequencies highly accurately, which cannot be done with ordinary frequency counters. 

■ Unique Sound Monitor Mode and Marker Pause Mode 

When measuring electric field strength or doing EMC measurements, there is often the need to monitor the sound. As well as having a conventional sound monitor in zero span mode, by means of a marker pause function, the R3261/3361 Series can monitor sound while doing panoramic reception measurements. 

■ Manual Sweep Function for Spot Measurement 

The sweep time in EMC or QP measurement is extremely long to complete measurement. But the sweep time when measuring the peak value is extremely short and measurement can be done in a short time. So the QP value is usually measured first at the peak, then at the necessary position. The manual sweep function of the R3261/3361 Series is a very handy and unique function to measure only a point specified by turning the rotary knob on the front panel.

■ Create Your Own Unique Menu 

The R3261/3361 Series spectrum analyzers are very functional, yet very easy to use because of the user-defined functions and define functions. The microprocessor built in to many measuring instruments improved the measurement accuracy and functions but they also made the systems very difficult to use. As a solution to this problem, the software menu method was developed. However, this method was still not satisfactory. ADVANTEST’s new concept solves most of these problems.

● User-defined function 

The user–defined function 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. 

● Define Function 

The software key menu, which corresponds to the keys on the main panel, can be displayed and changed by using this function. 

■ Fast Measurement with Measuring Window Function 

The R3261/3361 Series models have a measuring window function. In conventional analysis, the user picks up only necessary portions from all the display data with a marker. However, you may need to focus on only the part being displayed. This is accomplished by the measuring window function. The window specification may include not only a frequency but a level. The frequency and level are not fixed but can be specified to arbitrary values for flexible analysis. In addition, since marker and sweep operations are possible in a range set by the frequency and level, the measuring time can be reduced greatly
