Agilent Technologies' Capacitance Meter Sets New Standard For
Speed And Accuracy

Agilent Technologies Inc. has introduced the Agilent 4288A capacitance meter for high-speed testing of ceramic capacitors on the production line. The Agilent 4288A delivers the highest throughput and highest measurement accuracy of any available capacitance meter, and is 30 percent faster than the Agilent 4278A, the current industry leader.

The Agilent 4288A, successor to the Agilent 4278A, is designed to address the need of capacitor manufacturers for testing greater numbers of devices in less time with improved accuracy. In addition to reducing test time by 30 percent over the Agilent 4278A, the new instrument increases basic capacitance measurement accuracy to 0.07 percent at both 1 kHz and 1 MHz measurement frequencies, versus 0.10 percent at 1 kHz and 0.12 percent at 1 MHz achieved by the Agilent 4278A.

The Agilent 4288A is also the smallest and lightest capacitance meter available, which provides the most efficient use of space inside parts-handler systems. The instrument requires only a three-quarter-rack space versus the full-rack space required by the Agilent 4278A, weighs only 3 kg, versus 15 kg for its predecessor, and consumes typically half the power. It provides simultaneous testing on up to 64 channels, supports all of the parts handlers used by capacitor manufacturers, and employs the latest SCPI commands for programming.

The instrument also provides several new features, and incorporates as standard features nearly all of the capabilities that were options with its predecessor, including software-selectable frequency shifts of 2, 1 and -1 percent; as well as GPIB, handler and scanner interfaces. Up to 10 test setups can be stored in EEPROM, versus one in memory card with the Agilent 4278A. The Agilent 4288A also extends the calibration interval to one year, versus six months for the Agilent 4278A. The Agilent 4288A also includes a "resume" function in backup memory, which recovers the measurement setup automatically when the instrument is turned on. Multi-compensation load values are now independent for each channel, rather than common to each channel, as well.
