# Advantest R3132N 9 kHz to 3 GHz 75 Ω Spectrum Analyzer (Pre-Owned) # Advantest R3132N 9 kHz to 3 GHz 75 Ω Spectrum Analyzer (Pre-Owned) ## Key Features At A Glance - Frequency coverage from 9 kHz to 8 GHz across the series (R3132 to 3 GHz; R3162 to 8 GHz) - GPIB (IEEE-488) and RS-232 equipped as standard for automated measurement system construction - Signal purity of -105 dBc/Hz at 20 kHz offset and -100 dBc/Hz at 10 kHz offset - Total level accuracy of ±1.5 dB guaranteed by internal automatic calibration - 20 traces per second (typ.) for real-time waveform measurement - 6.5-inch TFT color LCD with VGA output and built-in 1 Hz resolution frequency counter - Standard ACP and OBW functions, QP detector, and 6-dB EMI bandwidth filters (9 kHz, 120 kHz, 1 MHz) - Available with 50Ω or 75Ω (R3132N) input impedance; optional 3 GHz tracking generator The Advantest R3132/3162 is a series of swept spectrum analyzers built for versatile measurement across a broad frequency range. The R3132 covers 9 kHz to 3 GHz and the R3162 extends coverage to 8 GHz, and the series can be tailored to a given task through a selection of available options. The series is positioned for applications such as Cable TV, EMC measurement, and digital mobile communications. For EMI precompliance work, 6-dB bandwidth filters for 9 kHz, 120 kHz, and 1 MHz are equipped as standard along with a QP detector, and an optional 200 Hz narrow resolution bandwidth filter can be added. ACP and OBW functions support evaluation of the transmission characteristics of radio systems, and the instrument can also measure the attenuation characteristic of filters or the frequency characteristic of cables when the optional tracking generator is fitted. ValueTronics stocks and holds its own inventory in a 20,000 square-foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Every used unit is inspected and functionally verified in-house before it ships, while new units ship factory-sealed exactly as received, so buyers know precisely what they are getting either way. ## Brand Heritage Advantest Corporation traces its roots to Takeda Riken, the Japanese instrument maker that adopted the Advantest name in 1985. ## Compare Other Models in This Series The R3132/3162 series comprises swept spectrum analyzers that share a common platform while differing chiefly in frequency coverage. The R3132 spans 9 kHz to 3 GHz, while the R3162 extends the upper limit to 8 GHz across multiple frequency bands. A 75Ω input variant, the R3132N, is offered for applications calling for 75Ω matching. All models can be customized through the same set of options and share the series' core measurement architecture, including internal automatic calibration, the 6.5-inch TFT color LCD, a built-in frequency counter, and standard GPIB and RS-232 interfaces. Each pre-owned model listed below is its own product page with condition-matched pricing. Select the model whose frequency coverage and input impedance match your application, then choose the pre-owned listing that fits your requirements. The primary difference across the series is frequency range: the R3132 reaches 3 GHz, while the R3162 reaches 8 GHz using banded coverage (Band 0 from 9 kHz to 3.4 GHz, Band 1- from 3.2 GHz to 7.5 GHz, and Band 1+ from 6.5 GHz to 8 GHz). The input attenuator range also differs, spanning 0 to 50 dB on the R3132 and 0 to 75 dB on the R3162. Input impedance is the other distinguishing factor: the R3132 and R3162 present a nominal 50Ω input, while the R3132N provides a nominal 75Ω input. The comparison table below details the per-model frequency, attenuation, and impedance figures.
