GDS-80S Crystal Oscillator Network Analyzer
Product Overview
The GDS-80S Crystal Oscillator Network Analyzer is a cost-effective crystal testing system designed for high-precision measurement and analysis of quartz crystal electrical parameters. It adopts advanced network analysis technology to achieve intelligent and efficient measurement and complies with relevant IEC 444 standards.
The GDS-80S supports two frequency ranges, 10 kHz–200 kHz and 1 MHz–100 MHz, and uses a π-network zero-phase method to measure series resonance frequency. A direct impedance measurement method is used to determine load resonance frequency and load capacitance.
The instrument can measure multiple important crystal parameters, including series resonance frequency Fr, load resonance frequency FL, series resonance resistance Rr, load resonance resistance RL, load capacitance CL, dynamic capacitance C1, dynamic inductance L1, quality factor Q, shunt capacitance C0, and frequency pulling capability Ts.
The load capacitance can be freely programmed from 1 pF to 200 pF, allowing the instrument to test crystals under different load capacitance conditions. Intelligent network analysis and calculation technology eliminates the limitations of conventional physical capacitor testing methods, reduces measurement errors, and minimizes the need for manual calibration.

Working Principle
The GDS-80S Crystal Oscillator Network Analyzer uses network analysis technology to determine the electrical characteristics of quartz crystal resonators.
For series resonance frequency Fr, the instrument uses the π-network zero-phase method. By analyzing the phase characteristics of the crystal under test, the system identifies the resonance point and determines the series resonance frequency and corresponding equivalent resistance.
For load resonance frequency FL and load capacitance CL, the instrument adopts a direct impedance measurement method combined with intelligent network analysis and calculation. The user can program the required load capacitance between 1 pF and 200 pF, enabling crystal parameters to be evaluated under different load conditions.
Compared with conventional testing methods using physical capacitors, the network analysis approach provides greater flexibility, reduces the influence of external components, improves measurement accuracy, and eliminates complicated manual correction procedures.
