High-Frequency LCR Meter – GW‑INSTEK LCR-8230A
The LCR-8230A is a model in GW‑INSTEK's LCR-8200(A) high-frequency LCR meter series. The instrument measures electrical parameters such as impedance, inductance, and capacitance over a wide frequency range and presents the results on a 7" color LCD.Features and Measurement Parameters
- Test frequency: DC and 10 Hz up to 30 MHz.
- Basic accuracy: ±0.08%.
- Measurement parameters (up to four simultaneously displayed): Impedance (Z), Inductance (Ls/Lp), Capacitance (Cs/Cp), AC Resistance (Rs/Rp), Quality Factor (Q), Dissipation Factor (D), Conductance/Admittance (G/Y), Reactance (X), Phase Angle (θ), Susceptance (B), and DC Resistance (Rdc).
- Output impedance: 25 Ω / 100 Ω (selectable).
- Internal DC bias: 0 to ±12 V.
- 7" LCD (800 × 480) for graphical and numerical display.
Measurement Methods and Automation
- List measurement: up to 15 steps with parameters such as frequency, Vac, Iac, DC bias, compensation, and BIN steps; trigger: AUTO, REPEAT, SINGLE.
- Sweep measurement: graphical sweep with two simultaneous sweep parameters (frequency, Vac, Iac, BIAS V, Keep Trace).
- Additional functions: Auto Level Control (ALC), corrections (Open/Short/HF Load/Load), V/I monitor, and comparator with PASS/FAIL/OK or BIN 1–9.
- The A-series (including LCR-8230A) offers equivalent circuit model analysis with 7 different models; 3-component analysis has 4 types and 4-component analysis covers 3 types.
Interface and Physical Information
- Standard interfaces: USB, GPIB, LAN, RS-232, and Handler; also USB Host and Trigger Input.
- Test signal levels (example values provided in manufacturer's specification): AC voltage and current ranges as well as DCR voltage 1 Vdc (40 mA max.).
