The Anritsu 54147A is a scalar network analyzer that measures RF and microwave signal amplitude across 10 MHz to 20 GHz. It delivers transmission, return loss, precision return loss, SWR, and power measurements with optional distance-to-fault and relative group delay capabilities. The instrument features three input channels—two standard (A and B) plus an optional reference (R)—enabling simultaneous dual-channel display and ratio calculations (A/R, B/R) for signal characterization across component and system test workflows.
