The Keysight N1911A P-Series Single Channel Power Meter is a precision instrument for measuring power across R&D, manufacturing, and service environments. It delivers accurate power characterization for complex wireless signals including WiMAX, LTE, and radar systems. The meter operates at 100 MSa/s real-time sampling with 14-bit resolution and 30 MHz video bandwidth, supporting both modern P-Series sensors and legacy 8480/E-Series/N8480 sensor families.
