# Vector Signal Analyzers

When engineers need to measure an input signal’s magnitude and phase, they use a vector signal analyzer. This electronic test equipment takes in-channel measurements, including spectral flatness, error vector magnitude, and code domain power. Used and refurbished vector signal analyzers are a smart choice for monitoring signals, including wireless local area network (WLAN), long-term evolution (LTE), and wideband code division multiple access (WCDMA). Engineers can measure and demodulate these signals during design and compliance testing.
