The Keysight N1912A is a dual-channel power meter engineered for precise RF power measurements across demanding test environments. This instrument combines high-speed sampling with advanced pulse analysis to characterize complex signals including WiMAX, DME, and HSDPA formats. The N1912A delivers measurements of average power, peak power, peak-to-average ratio, and pulse timing parameters with 100 Msamples/sec continuous sampling and ≤13 ns rise/fall time performance above 500 MHz.
