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. 

■ 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

■ 120 dB Dynamic Range CRT Display 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 swee.

■ Burst Signal Analysis (Optional) Among many of today’s popular media such as VCRs, 8 mm video, DATs, laser disks, floppy disks and TV, there are many which use revolving heads or intermittent signals. As a company devoted to producing measuring instruments, ADVANTEST has worked on producing equipment for the measurement of these intermittent (burst) signals from an early stage. Functions for burst signal measurement are available as an option in the R3261/3361 Series, to further expand its signal analysis ability, and contribute to the development of the latest technologies such as AV equipment. Applications 

• Measurement of VCR, 8 mm video, and DAT heads, as well as tape noise 

• Evaluation of element plate characteristics and noise in laser disks 

• Noise evaluation in TV1H (horizontal line) 

• Noise measurement of only picture signal in TV cameras 

■ Controller Function For Automatic Measuring (Optional) An optional controller function can be installed into the R3261/ 3361 Series. It uses the easy–to–understand BASIC computer language, and can be used to control itself and another GPIB device connected to the GPIB port. Programs can be entered on a familiar, often–used terminal, or a personal computer in terminal mode. Parallel I/O devices can be controlled by means of the controller function, and automatic measurements with jigs are possible. For small–scale systems, these functions are extremely effective in terms of cost and space. Entered programs, measurement conditions, waveform data or other items can be saved on an IC memory card, so that when running the program, only the spectrum analyzer need be used.
