Benefits of the E4981A Ceramic Capacitor Production Tester
- Accurate, high-speed measurement of capacitances.
- Wide measurement range from small to large capacitance 0 F to 2.0 mF.
- Test of ceramic capacitors and high-value multi-layer ceramic capacitors.
Keysight E4981A Capacitance Meter
The Keysight E4981A capacitance meter is an ideal solution for the reliable, high-speedmeasurement and test of ceramic capacitors in the production lines. The E4981A realizes the measurement capabilities of capacitance from small to large values with accurate measurements. The capacitance meter contributes improvements of the test throughput, while attaining excellent component quality for ceramic capacitor testing.
- High speed measurement with 2.3 ms (1 MHz), 3.0 ms (1 kHz), 11.0 ms (120 Hz).
- Accurate C-D testing with basic accuracy 0.07%, 0.0005.
- 9 bin sorting.
- 256 multi-channel correction.
- Compatible SCPI command and handler/scanner interfaces with the obsolete models 4268A and 4288A.
- Test signal level compensation for high value ceramic capacitor tests.
- Versatile PC connectivity (LAN/Ethernet, USB and GPIB).
- Accurate and repeatable measurements, even small capacitance can be measured.
- Enhanced functions for production test: Enhanced contact failure detections, synchronous source, frequency shift (±1%, ±2%) at 1 MHz, faster data transfer.
