Agilent / HP / Keysight 4287A
4287A RF LCR Meter, 1 MHz to 3 GHz
Description
The 4287A RF LCR meter offers accurate, reliable and fast measurements from 1 MHz to 3 GHz to improve quality and throughput of electronic component testing in production lines.
The 4287A employs the direct-current voltage-measurement technique, as opposed to the reflection-measurement technique, which yields accurate measurements over a wide impedance range.
Key Points
1 MHz to 3 GHz, with 100 kHz steps
Wide impedance measurement range from 200 m ohm to 3 k ohm
1% basic accuracy
Superior measurement repeatability at low test signal level
High-speed measurements: 9 ms
