Hioki IM3570 Impedance Analyzer (5MHz)

Hioki IM3570 Impedance Analyzer (5MHz)

With this new IM3570 Impedance Analyzer, an LCR meter and an impedance analyzer capable of measurement frequencies of 4 Hz to 5 MHz and test signal levels of 5 mV to 5 V have been combined into one measuring instrument. Advanced capabilities include LCR measurement with AC signals, resistance measurement with direct current (DCR), and sweep measurement which continuously changes the measurement frequency and measurement level.

The IM3570 facilitates high-speed continuous measurement under different measurement conditions and measurement modes, so inspection lines which up to now have required multiple measuring instruments can be equipped with just one device.

Advantage #1 – Measurement time shortened

The measurement time has been shortened from previous models, achieving maximum speeds of 1.5ms* (1 kHz) and 0.5ms* (100kHz) in LCR mode. This is a significant increase in speed compared with previous Hioki products (3522-50 and 3532-50 with basic speed of 5ms). Faster speed contributes to an increase in test quantities. Furthermore, sweep measurement, which requires multiple points to be measured, realizes the quick speed of 0.3ms per point.

Advantage #2 – Low-impedance measurement accuracy improved

A one-digit improvement in repeat accuracy during low-impedance measurement has been achieved compared with previous Hioki products.

For example, when the condition is 1 mΩ (1V, 100 kHz) and the measurement speed is MED, stable measurement with a repeat accuracy (variation)* of 0.12% is possible, making this instrument suitable for 100 kHz ESR measurement.

* Repeat accuracy (variation) is calculated based on the difference between the maximum and minimum values.
