Advantest R3132/R3132N/R3162 Spectrum Analyzer

The R3132/3132N/3162 are a low-cost implementation of a portable spectrum analyzer with the key performance characteristics manufactured to address a variety of measurements.

Built around a newly developed direct digital synthesizer, the spectrum analyzer offers a frequency span accuracy of ±1% or less in frequency ranges of 9 kHz to 3 GHz (R3132/3132N), and 9 kHz to 8 GHz (R3162). The built-in auto-calibration feature assures an over-all level accuracy of ±1.5 dB. Dramatically enhanced distortion characteristics of a 1 dB gain compression point of 0 dBm input, a second-order harmonic distortion of -80 dBc, and a two-signal third-order intermodulation distortion of -80 dBc make measurement in a 117 dB broad dynamic range possible. The new synthesized local oscillator enables the R3132/3132N/3162 to speed up sweep time, updating as many as 20 traces per second.

The R3132/3132N/3162 personal spectrum analyzers are designed to fit into a broader range of applications than ever before.

Features

Reinforced basic functions

Basic functions are reinforced so that R3132/3132N/3162 can be used in various fields. For example, the internal automatic calibration function guarantees the total level accuracy of ±1.5 dB, level correction factor can be stored in the internal memory, DDS is employed to improve frequency reading accuracy, and frequency span error is lowered to less than 1%.
As a result of increasing the sweep repetition cycles by improving the synthesized local oscillator, 20 cycle/s (typ.) of trace data rewriting becomes possible, enabling far more real-time waveform measurement. High speed GPIB increases the throughput of automatic measurements, thus saving valuable time.

Abundant measurement functions

For EMI pre-compliance measurements, 6-dB bandwidth filters for 9 kHz, 120 kHz and 1 MHz as well as QP detector are equipped as standard. An optional 200 Hz narrow band-pass filter can be added.

High-speed time domain measurement functions, which are indispensable for mobile communications, an optional 50 µs sweep is effective. For power measurements, AVG. POWER and TOTAL POWER processing functions are provided.

Counter function, ACP, OBW, dBc/Hz, %AM and many other functions are provided for various measurement purposes.

The internal preamplifier is equipped as standard.

Even for signals which are lower in level than the average noise level, the preamplifier ensures level calibrated, high-accuracy measurements.

For measuring the attenuation characteristic of filters or the frequency characteristic of cables, etc., a built-in tracking generator is available as an option. Because the output level can be set in a wide range, it is possible to measure amplifier gain, frequency response, etc.

Easy-operation interface

The high-resolution, 6.5-inch TFT color LCD realizes easy-to-see display of data. Display data is output through the VGA video output on the rear panel and can be output to an external monitor.

Measured waveform data and set values can be saved in or recalled from the internal memory. Using the floppy disk drive, which is equipped as standard, management of a large amount of data is made possible. Text data or BMP data saved on floppy disk is also useful for creating documents and reports.

The hard-copy function is adapted to ESC/P. ESC/P-R and PCL, measured data can be printed out on general-purpose printers.

GPIB and RS232 are equipped as standard.

Compact, lightweight design

This product features a new frame design making it more compact (approximately 424(W) × 177(H) and 300(D) mm) and lighter (about 14kg). In particular, the short depth of 300mm allows more effective utilization of the work space. A panel cover is supplied as standard to prevent damage to the analyzer while carrying or moving it.
