Agilent/Keysight N1911A

The Agilent/Keysight N1911A is a single-channel power meter engineered for precision measurement of pulsed and modulated signals across a broad frequency spectrum. It delivers peak power, average power, peak-to-average ratio, and detailed pulse characterization—rise time, fall time, and pulse width—making it ideal for WiMAX, LTE, radar, and other wireless signal analysis. The instrument combines real-time sampling at 100 Msamples/sec with 30 MHz video bandwidth and sub-13 ns rise/fall time performance above 500 MHz, enabling accurate capture of fast transients down to 50 ns minimum pulse width.
