LTT24 - Power Analyzer


With a resolution of 24 bits and a sampling rate up to 4 MHz per channel, the LTT24 Power Analyzer is ideal for precise, fast and very fast measurement requirements.

LTT24 - Precision measuring instrument

An all-rounder - winner of the MESSTEC & SENSOR Masters 2013 Award

Just like in a good orchestra, the innovative concept of the LTT24 precision measuring instrument is based on the optimization of the individual components, such as the preamplifier and the A/D converter, power supply unit, sensor power supply, sensor cables etc. and their harmonious coordination within the overall system. The LTT24 Power Analyzer is so well thought out that there is actually no room for measuring errors! Slow, fast and very fast channels can be combined within one modular device.

By consistently minimizing all sources of error, the preamplifier in the LTT24 precision measuring instrument can work with full precision. Distortion and noise combined are almost -100 dB, enabling a measurement result with an actual ENOB (effective number of bits) of 16 bits across a wide range of frequencies and amplitudes.

The internal power supply units of the LTT24 Power Analyzer measuring devices work highly synchronously at half the ADC clock rate, remaining invisible over the entire bandwidth from DC to 2 MHz. The common mode rejection of the differential amplifiers – decisive for the elimination of external, mostly high-frequency interferences via the sensor cables – allows for an adjustment from DC to over 1.7 MHz bandwidth to more than -100 dB at the push of a button.

All measuring channels e.g. for volts, current, resistance, ICP®, LVDT, strain gage, charge etc. are galvanically isolated and offer stable sensor supplies down to the MHz range – with a measuring resolution more precise than -117 dB.
