# Anritsu MS4630B Network Analyzer (Pre-Owned) # Anritsu MS4630B Network Analyzer (Pre-Owned) ## Key Features At A Glance - Network analyzer covering 10 Hz to 300 MHz with 0.01 Hz frequency resolution - 120 dB dynamic range (RBW: 1 kHz) for out-of-band filter measurement - High-speed sweep of 150 µs per measurement point via synthesizer and DSP - Group delay measured at a resolution of 1/10,000 of the measurement range - Up to 10 independent markers per channel with simultaneous marker list display - Filter analysis: 3 dB bandwidth, center frequency, in-band ripple, out-of-band attenuation - Resonator analysis for resonance frequency, impedance, and equivalence constants - GPIB (IEEE 488.2) and PTA standard for automation; RS-232C/Centronics optional The Anritsu MS4630B is a network analyzer that operates from 10 Hz to 300 MHz, built for high-speed, accurate evaluation of IF filters, resonators, and similar devices on electronics production and inspection lines. It combines a high-speed synthesizer with digital signal processing to deliver fast, repeatable device measurements suited to production-throughput demands. Its measurement work centers on the applications it was designed for: evaluating IF filter resonance and group delay characteristics, and measuring the impedance characteristics of resonators used in AV equipment and personal computers. Crystal resonators can be tested by combining the analyzer with a π-circuit jig such as the MA1506A, and filter pass/fail screening is performed in real time using the single and segmented limit-test functions. ValueTronics keeps the MS4630B and the wider test-and-measurement catalog in stock at our own 20,000 square-foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois, where we hold and manage our inventory directly. Every used unit is inspected and functionally verified in-house before it ships, while new units leave the warehouse factory-sealed exactly as received. ## Accessories Supplied - Power cord, 2.6 m: 1 pc - F0013 Fuse, 5 A: 2 pcs - W1534AE MS4630B operation manual (main frame): 1 copy - W1535AE MS4630B 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 Accuracy (standard): Aging rate ≤1 x 10–6/day (15 minutes after power-on) Accuracy (standard): Temperature characteristics ≤±5 x 10–6 (0° to +50°C) Accuracy (Option 13: High-stability reference oscillator): Aging rate ≤±2 x 10–8/day (24 h after power-on) Accuracy (Option 13): Temperature characteristics ≤±5 x 10–8 (0° to +50°C) Input Channel No. Standard: 2 (R, TA);

AC 0 dBm / DC ±20 V (1 MΩ). > **Important:** Reflection and impedance characteristic measurements require an external transducer (e.g., a reflection bridge or impedance probe), which is not supplied with the main frame and must be ordered separately (see Optional accessories). > **Important:** Crystal resonators are tested by combining the MS4630B with a π-circuit jig such as the MA1506A; the floating admittance around the jig is eliminated using the MS4630B π-network calibration function and the jig calibration standard. ## About this Pre-Owned unit This pre-owned unit is inspected and functionally verified in-house before it ships and is backed by our pre-owned warranty.
