In addition, the R3172 achieves best-in-class www.cniacs.com performance at an average display noise level of -106 dBm (426.5 GHz, RBW 1 kHz) and SSB phase noise level (26.5 GHz, 20 kHz offset).

The R3172 is designed to withstand a certain amount of noise on the AC power line and should be used in low noise areas. A noise reduction filter helps avoid ambient noise.

The R3172 has an exhaust cooling fan on the rear panel and a front-facing exhaust port on the bottom. Users are advised not to block these areas as the resulting internal temperature rise can affect measurement accuracy.

The R3172 is safe for use at a maximum altitude of 2000 m above sea level, installation category II, contamination level 2.

To remove dirt from the exterior of the spectrum analyzer, wipe or brush the surface with a soft cloth or small brush. Hardened dirt can be removed with a cloth that has been soaked in water containing a mild detergent.

The R3172 was developed as a personal use spectrum analyzer capable of being used in a wide range of applications.

Basic functions

Basic functions are reinforced so that R3132/3162 can be used in various fields.  For example, the internal automatic calibration function guarantees the total level accuracy of ±1.5dB, 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%.

The R3132/3162 offer wider dynamic range and lower 2nd and 3rd distortion by improving 1dB compression point.

As a result of increasing the sweep repetition cycles by improving the synthesized local oscillator, 20 traces/second (typ.) data rewriting becomes possible, enabling far more real-time waveform measurement.

high speed GPIB increase, the throughput of automatic measurement.

For many applications

For EMI precompliance measurement, 6-dB bandwidth filters for 9kHz, 120kHz and 1MHz as well as QP detector are equipped as standard.  Optional 200Hz narrow RBW filter can be added.

For high-speed time domain measurement function which is indispensable for mobile communications, optional 50µs sweep is effective.

The R3132/3162 series spectrum analyzer has ACP and OBW operation function indispensable for evaluating the transmission characteristic of radio system.

With various other functions such as AUTO TUNE, 1Hz resolution frequency counter, dBc/Hz, %AM, and PASS/FAIL test by limit value, the R3132/3162 series can easily perform several types of measurements.

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

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

The R6144 is precision voltage and current generators ideal for evaluation of precision circuits and parts as well as calibration of temperature controllers.

Description:

A spectrum analyzer is a broadband, very sensitive receiver.

It operates on the principle of a “super-aberrant receiver”, converting higher frequencies (usually ranging up to tens of gigahertz) into measurable quantities.

The received spectrum is slowly scanned through a series of pre-selected frequencies, which are converted to measurable DC levels (usually on a logarithmic scale) and displayed as such on the Advantest R3272’s CRT.

The CRT displays the received signal strength (y-axis) versus frequency (x-axis).
