# Anritsu MS4630A 10 Hz to 300 MHz Network Analyzer (Pre-Owned) # Anritsu MS4630A 10 Hz to 300 MHz Network Analyzer (Pre-Owned) ## Key Features At A Glance - Frequency range 10 Hz to 300 MHz with 0.01 Hz resolution - Measurement range ≥120 dB dynamic range (RBW: 1 kHz) for fast out-of-band filter attenuation measurement - Fast 150 µs/measurement-point sweep speed using high-speed synthesizer and DSP processing - High-accuracy group delay measurement at 1/10,000-of-range resolution - Up to 10 independent multi-markers per trace with tabular marker-list display - Built-in filter (3 dB BW, fo, ripple, attenuation) and resonator (Fr, Zr, equivalence) analysis functions - Single and segmented limit-test functions for real-time pass/fail device evaluation - GPIB (IEEE488.2) and PTA parallel interface standard; RS-232C/Centronics via Option 02 The MS4630A is a network analyzer covering 10 Hz to 300 MHz, designed for electronics production lines that demand fast, accurate device measurements. It is well suited to high-speed evaluation of IF filter resonance and group delay characteristics, and to evaluating the impedance characteristics of resonators used in AV equipment and personal computers. A fast sweep speed of 150 µs per measurement point is achieved through a high-speed synthesizer and digital signal processing, while strengthened post-processing data-analysis macros increase total production throughput. Its listed applications center on filter and resonator characterization on production and inspection lines. The instrument measures filter characteristics such as 3 dB bandwidth, center frequency (fo), in-band ripple, and out-of-band attenuation, which are digitally processed and analyzed at high speed. Dedicated resonator analysis functions evaluate resonance frequency (Fr) and resonance impedance (Zr), with Resonator 2 adding resonator equivalence measurement. Single and segmented limit-test functions provide real-time pass/fail evaluation of devices under test. ValueTronics stocks and holds its own inventory in a 20,000 sq ft secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Every pre-owned unit is fulfilled directly from that facility; used units are inspected and functionally verified in-house against the original manufacturer's specifications before they ship, while new units ship factory-sealed exactly as received. ## Accessories Supplied - J0017 Power cord, 2.5 m: 1 pc - F0013 Fuse, 5 A: 2 pcs - W1248AE MS4630A operation manual (main frame): 1 copy - W1249AE MS4630A operation manual (remote control): 1 copy ## Product Core & Specifications Specification Value Measurement Items Transmission characteristics (ratio measurement) Amplitude, phase, group delay Reflection/impedance characteristics Amplitude, phase (with external transducer) Level characteristics Absolute amplitude Frequency Range 10 Hz to 300 MHz Resolution 0.01 Hz Aging rate (standard) ≤1 x 10–6/day (15 minutes after power-on) Temperature characteristics (standard) ≤±5 x 10–6 (0° to 50°C) Aging rate (Option 13: High-stability reference oscillator) ≤±2 x 10–8/day (24 h after power-on) Temperature characteristics (Option 13) ≤±5 x 10–8 (0° to 50°C) Input Channel No. Standard: 2 (R, TA);
