Spectrum Analyzers

R3265A/3265AP/3365A Series offers a large–sized CRT screen in a portable unit and a wide frequency range, allowing measurements from 100 Hz to 8 GHz in a single sweep. Due to a newly developed high purity synthesizer, the series also provides excellent spectral purity of –110 dBc/Hz at 2.6 GHz (10 kHz offset frequency). This unit performs especially well in measuring the spurious emission intensity of new mobile communications equipment, the bandwidth of occupied frequencies and signal leakage from adjacent channels. In the low–noise mode, the series has a high-input sensitivity of –145 dBm (1 MHz to 3.6 GHz), so it can easily measure low level signals. The R3265A Series is provided with a BASIC controller as a standard feature. This feature allows measured data or set conditions to be stored and the free construction of automatic measurement systems without the need for external controllers. A preselector for low frequencies has been added to the R3265A, enabling the unit to realize a dynamic range of 100 dB and higher for carrier waves of 250 MHz and higher. The R3365A has a built–in tracking generator and is ideal for measuring frequency characteristics when setting up or maintaining digital radio base stations.

Product Overview

Brand and model: Edwin (Advantest) R3265A

Type: Portable Spectrum Analyser

Main purpose: Suitable for spectrum analysis in digital and analogue communication, especially good at measuring the parasitic emission intensity of mobile communication equipment, occupied frequency bandwidth and signal leakage of neighbouring channels.

Technical specifications

Frequency range: 100Hz to 8GHz, covering a wide range of communication bands.

Frequency accuracy: ±110Hz at 1GHz frequency point, ensuring the accuracy of measurement.

Resolution bandwidth range: 10Hz to 3MHz, which can be adjusted as required to optimise measurement performance.

High input sensitivity: up to -145dBm in low-noise mode (in the 1MHz to 3.6GHz range), making it easy to measure weak signals.

High signal purity: A high signal purity of -110dBc/Hz (10kHz offset frequency) can be obtained at 2.6GHz using the newly developed high purity synthesiser.

Functions and Features

Time-domain analysis function: Incorporating a time-domain analysis function enhances its capability in complex signal analysis.

Large CRT display: Despite being a portable instrument, it incorporates a large CRT display for easy use in outdoor or mobile environments.

Multi-cursor function: With the multi-cursor function, frequency and level values displayed by multiple cursors can be listed, enhancing operation capability.

Memory Function: Measurement settings, measurement data, and user-defined values can be stored or recalled, greatly reducing the time required for measurements and reducing repetitive panel settings.

High-speed scanning: Provides high-speed scanning and digital readout at 5 us/div, improving measurement efficiency.

Gate Scanning Function: Supports gate scanning function, further extending its use in specific applications.

Application Scenarios

Communication industry: Used to measure and analyse the spectrum characteristics of various communication devices, such as mobile phones and base stations.
