E4980AL Precision LCR Meter vs. GW LCR-821 – Competitive Comparison
散页
- Combination of accuracy, speed and versatility
- Wide variety of accessories
- Upgradability
For basic testing or evaluation of electronic components such as capacitors and materials, wide impedance measurement range and test frequency range are required. For example, the high-value capacitance is measured at 120 Hz, and the low-value capacitance is measured at 1 MHz.
e.g. 10 mF capacitor: |Z| = 133 mΩ at 120 Hz
1 pF capacitor: |Z| = 159 kΩ at 1 MHz
