The Wiltron 6407 is a scalar network analyzer that characterizes transmission, return loss, and absolute power across 1 MHz to 1000 MHz. It combines a broadband, high-resolution signal source with a two-channel scalar network analyzer, delivering 76 dB dynamic range (+16 dBm to -60 dBm) with 0.002 dB resolution. The resident microprocessor enables automated error correction, non-volatile normalization storage, and hard-copy data output.
