Agilent / Keysight E8241A PSG-L Series Performance Signal Generator, 20 GHz

The Agilent/Keysight E8241A PSG-L Series Performance Signal Generator delivers precision RF signal generation from 250 kHz to 20 GHz, with optional millimeter-wave extension to 110 GHz via external modules. Built for aerospace, defense, and wireless communications testing, the instrument combines frequency accuracy, low phase noise, and flexible modulation to support product development, verification, and manufacturing workflows. Output reaches +13 to +20 dBm at 20 GHz, with level accuracy of ±0.7 dB and 0.01 dB resolution. Frequency resolution is 0.01 Hz across the full band.
