The Keysight N1045B is a 60 GHz electrical remote sampling head for high-bandwidth characterization of signals in signal integrity and high-speed digital design applications. This sampling module integrates with the N1000A DCA-X mainframe and N1010A FlexDCA software to deliver precision equivalent-time sampling with 90 fs rms intrinsic jitter. Available in 2-channel or 4-channel configurations, the N1045B supports user-selectable bandwidth settings from 20 GHz to 60 GHz (typical 65 GHz), accommodating a filter range of 10 GHz to 70 GHz. The module features 1.85 mm electrical connectors with male or female termination options, handles maximum input voltages of +2V, and achieves a maximum sample rate of 250 kSa/s. TDR/TDT capability enables comprehensive device and transmission line characterization.
