The Keysight (formerly Agilent/HP) N1912A is a dual-channel P-Series 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 continuous 100 MSa/s sampling for precise time-domain and statistical analysis, including peak power, average power, peak-to-average ratio, pulse profiling, and CCDF measurements. It maintains extensive backward compatibility with legacy 8480 and E-Series sensors for conventional average power measurements across a wide dynamic range and frequency span.
