The Keysight N1046A is a high-performance electrical remote sampling head module designed for the 86100D DCA-X Digital Communication Analyzer mainframe. These compact modules extend measurement capabilities for high-speed signal acquisition and analysis, delivering the smallest form factor among oscilloscope remote heads to enable direct or near-direct connection to the device under test. The N1046A supports up to 16 channels across multiple modules and operates with equivalent-time sampling at 250 kSa/s maximum, achieving intrinsic jitter as low as 90 fs RMS when paired with an 86100D-PTB equipped mainframe.
