The Keysight N1911A (formerly Agilent) is a P-Series single-channel power meter designed for high-performance RF and microwave power measurements. When paired with N192XA wideband power sensors, it provides a 30 MHz video bandwidth and 100 MSa/s continuous real-time sampling, enabling precise peak, average, and peak-to-average ratio measurements as well as advanced time-gated analysis (rise time, fall time, pulse width). The N1911A is also backward compatible with legacy 8480 and E-Series sensors, offering broad frequency coverage from 9 kHz to 110 GHz and a wide dynamic range from -70 to +44 dBm.
