GSP-9300B

The GSP-9300B is GW Instek’s 3 GHz spectrum analyzer offering 0.025 ppm frequency stability, a built-in preamplifier, and a 50 dB attenuator for high dynamic range measurements. Its -149 dBm/Hz sensitivity and comprehensive measurement suite including P1dB, harmonic distortion, channel power, ACPR, SEM, TOI, and N-dB bandwidth make it a versatile tool for RF design and production test. Spectrogram, topographic, and dual-view display modes provide multiple perspectives on signal behavior over time.
