R3261/R3361 Series Spectrum Analyzers

The R3261/R3361 Series spectrum analyzers use a synthesized technique to cover wide frequency bands: 9 kHz to 2.6 GHz (R3261C, R3361C) or 9 kHz to 3.6 GHz (R3261D, R3361D). These compact analyzers also offer high-performance functions, such as the 1 Hz resolution frequency setting function and 1 Hz resolution frequency counter function.

The R3261/R3361 Series spectrum analyzers are easy to operate because they incorporate unique features such as user-defined and measuring window functions. Weighing only 15 kg (33 lbs.) the analyzers are small and useful for measurement and analysis of all kinds, from manufacturing to research and development.

The analyzers have an internal controller function (Option 15), parallel I/0, and GPIB interface for line connection and automatic measurement, so the user can create the optimum system configuration.

Choose From Six Models, Depending Upon Your Application

The R3261/R3361 Series consists of six models. All models feature high performance and a set of features and functions for various applications.

1 Hz Resolution Synthesizer

The R3261/R3361 Series portable spectrum analyzers are based upon a synthesized system, so the center and start/stop frequencies can be set with a resolution of 1 Hz. The synthesizer, featuring 1 Hz resolution, is a powerful tool ideal for waiting, receiving, or spot measurement in the zero-span mode.

1 Hz Resolution Frequency Counter

The frequency counter built into the R3261/R3361 Series features 1 Hz resolution. One of the advantages of these analyzers is that they can measure the modulated frequency or spurious frequency of a radio system that cannot be measured with an ordinary frequency counter simply by setting a marker. In addition, the ability to measure weaker signals than a frequency counter can extend the application range from broadband panoramic measurement to weak signal measurement.

Manual Sweep Function for Spot Measurement

EMC measurements using the quasi-peak (QP) detector require an extended sweep time. However, the time required to measure the peak value can be shortened using the manual sweep function.

Create Your Own Unique Menu

The R3261/R3361 Series spectrum analyzers are very functional and very easy to use because of the user-defined functions:

Fast Measurement with Measuring Window Function

The R3261/R3361 Series allows the user to define both frequency and level ranges within a span for analysis. This powerful tool enables faster measurement times over frequencies and levels of interest.

Option 1K includes a suite of CDMA test routines which can be accessed through softkey menus. Specific CDMA measurements include channel power, total power across the span, average power, and peak power. The softkey menu for a test along with measured data (waveforms) can be stored in memory cards via the front panel.
