Keysight 4287A is a high-performance RF LCR meter covering the frequency range from 1 MHz to 3 GHz. It adopts direct voltage measurement technology instead of reflection measurement technology, enabling accurate measurements over a wide impedance range. Its core advantage lies in balancing measurement accuracy, speed and reliability, which can significantly improve the quality and throughput of electronic component testing in production lines, and is widely applicable to R&D verification and batch inspection of components in the RF field.
-
Frequency and measurement range: Frequency covers 1 MHz-3 GHz with 10 kHz resolution, supporting list sweep (up to 32 points per sweep); impedance measurement range is 200 mΩ-3 kΩ, measurable parameters include 12 key electrical parameters such as |Z|, |Y|, L, C, R, D, Q.
-
Accuracy and repeatability: Basic measurement accuracy up to ±1.0%, maintaining excellent measurement repeatability even at low test signal levels (minimum 4.47 mVrms voltage, 0.0894 mArms current), reducing data averaging time.
-
Measurement speed: The fastest single-point measurement time is only 9 ms, greatly improving test efficiency and adapting to high-speed testing needs in production lines.
-
System compatibility: Equipped with GPIB, LAN (10Base-T/100Base-TX auto-switching) and handler interface, supporting fast networking with test fixtures and PCs; 1m/2m test head cables can connect to DUTs at close range without additional errors.
-
Operation and storage: Equipped with 8.4-inch color LCD display with 5-digit resolution, built-in approximately 18 GB hard disk and 1.44 MB floppy disk, supporting open/short/load calibration and fixture length compensation.
-
Environmental adaptability: Power supply supports 90V-132V/198V-264V auto-switching, operating temperature range 5℃-40℃, and can reach optimal measurement status after 30 minutes of warm-up.
