Keysight (formerly Agilent T&M) 8981B Vector Modulation Analyzer
Manufacturer Keysight (formerly Agilent T&M)Description
Description
The Keysight 8981B is a used Vector Modulation Analyzer. Displays phase and amplitude modulation vs. time. Analyzes analog I and Q signals, DC to 350 MHz. 50 to 200 MHz modulated IF input range. HP-IB. The HP 8981B vector modulation analyzer (and HP 8780A/8782B vector signal generators) can be used to adjust and troubleshoot I/Q modulators, demodulators, and I/Q modulated signals used in digital mobile radio, microwave radio, and the transmission of digital video. The analyzers can be connected to the I/Q outputs of a demodulator in a receiver, or to IF test points. Once connected, the 8981B displays constellations, EYE diagrams, and vector diagrams of digital modulation formats such as QPSK, 16QAM, 64QAM, and 256QAM. The analyzer also makes statistical measures of system quality such as closure, lock angle error, and quadrature error. Through these “constellation analysis” techniques, transmission quality can be measured and monitored to detect degradations in the transmission link before link bit error rates reach unacceptable levels.
