The 4268A is a capacitance meter from Agilent. Capacitance meters are used to measure discrete capacitors and come in bench and portable varieties.
The Agilent 4268A Capacitance Meter offers the ability to test high value multi-layer ceramic capacitors at a constant large test signal level and at high speed. The constant test level feature allows the MLCCs to be tested, in compliance with IEC 384-10 standard, for up to 70 uF at 1 V RMS at 1 kHz. 120 Hz measurement ensures the constant 1 RMS test signal for up to 600 uF. The Agilent 4268A can provide measured values along with comparator results within 25 ms, maximizing test throughput in MLCC production lines.
