The Anritsu MS4630B is a network analyzer covering 10 Hz to 300 MHz, designed for high-speed evaluation of IF filters, resonators, and similar passive components. The instrument measures transmission characteristics (amplitude, phase, group delay), reflection and impedance characteristics, and absolute level characteristics, presenting results on a 6.5-inch color LCD with up to two channels and four traces displayed simultaneously.
Per the datasheet, the MS4630B is suitable for electronics production lines that demand fast and accurate device measurements. It is particularly well suited to accurate high-speed evaluation of IF filter resonance and group delay characteristics, as well as evaluating the impedance characteristics of resonators in AV equipment and personal computers. Dedicated filter and resonator analysis keys allow filter parameters (passband, attenuation band, insertion loss, center frequency, Q, shape factor) and resonator parameters (Fr, Fa, Zr, Za, equivalent-circuit constants) to be evaluated with a single key stroke.
Anritsu Corporation is a Japanese precision measurement company with a long history in RF, microwave, and network analysis instrumentation. The MS4630B network analyzer is part of Anritsu's standalone product line and was not formed through a brand acquisition or rebranding event.
