Overview
The R3172 and R3182 are low-cost portable spectrum analyzers capable of performing direct input measurements at a maximum frequency 26.5 and 40 GHz respectively.Adopting newly designed RF circuitry, both the R3172 and R3182 aim for improved basic performance with their 40 GHz direct input capability. Further, the R3172 and R3182 achieve "best-in-class" performance for average display noise levels of -104 dBm (at 26.5 GHz, RBW 1 kHz) and -106 dBm (at 40 GHz, RBW 1kHz) respectively, and SSB phase noise levels of -91 dBc/Hz (at 26.5 GHz, 20 kHz offset) and -85 dBc/Hz (at 40 GHz, 20 kHz offset) respectively.Operating frequencies for radio communi-cations have increasing tendency to shift to higher frequencies. Accordingly, the R3172 and R3182 have been developed as personal-use spectrum analyzers capable of use in a wide range of applications from development to manufacturing of high fre-quency modules, devices, etc.
Feature
Along with the increasing variety of communication methods, the high frequency devices and modules that affect the fundamental performance of such communications are required to deliver higher performance.The R3182 is a high performance analyzer with an average display noise level of -106 dBm/RBW 1 kHz at 40-GHz.This enables a wider relative measurement range when measuring high frequencies or weak signals against a reference waveform.The R3172/3182 also provide high performance with SSB phase noise of -91 dBc/Hz (for R3172 @26.5 GHz/20 kHz offset) or -85 dBc/Hz (for R3182 @40 GHz/20 kHz offset) by providing an internal local transmitter with a high level of purity.
A variety of optional external mixers are available for the R3172 /3182 spectrum analyzer for measuring various high-frequency signals. By selecting the optimum option, the measurement frequency can be set from 26.5 GHz to 110 GHz. Since the frequency characteristics specific to each mixer arecorrected and the data is saved in the internal memory of R3172 /3182, the level can be read directly.
The R3172/3182 are equipped with a 6-dB bandwidth filter of 9 kHz/120 kHz/1 MHz and a QP detector. In addition, an optical 200-Hz narrow band-pass filter is available, enabling noise measurement of high frequency bands that will be increasingly in demand in the future.The R3172/3182 support the computing functions AVE POWER and TOTAL POWER for power measurement, and are also equipped with a frequency counter and a preamplifier up to 3 GHz as standard, supporting a variety of applications.
