LTT24 - fast precision measuring device

With a resolution of 24 bits and a sampling rate up to 4 msample per channel, the LTT24 is data acquisition and recorder and analysis measurement - all-in-one

LTT24 is ideal for precise high speed data measurement.

LTT24 - Precision measuring instrument

The functionality of the integrated preamplifier allows the individual connection of various sensors from e.B volts, current, strain gauges, ICP®, charge, PT100 etc. The 24-bit converted signals are stored highly synchronously on an internal SSD at up to 4 MHz per channel. The analog output is via 20 bit DAC with up to 2 MS/s/Ch.

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.

LTT24 - modulare measuring instrument

The internal power supply units of the LTT24 fast 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.

The LTT24 high-speed measurement device is escpacially for reseach and development. Slow, fast and very fast channels can be combined within one modular device.

LTT24 - Data acquisition instrument for research and development

The LTT24 impresses with its market-leading combination of signal quality, bandwidth and flexibility.

Due to the large number of possible combinations of channel numbers and supported sensors and functions, the LTT24 can be used for a wide variety of applications, as a transient recorder, sensor cord or as a PC-based datalogger. The LTT24 in a rugged housing is ideal for research and development, laboratories and crash tests.

For example

  • automotive industry, for noise analysis, for component testing, for engine tests, as a tape drive replacement in all areas
  • EMC measurements, in space travel for materials research and observatories,in the defence industry during mine protection tests or in ballistics
  • OEM test bench construction, f. e. for turbochargers, airbags, electric motors or turbines
  • Body sound measurement, crack detection, material testing, as a tape drive replacement and even in recording studio recordings

Recording analog signals and reproducing them at a later time with high precision analog is just one of the many possibilities of the LTT24 precision meter.

With the rugged LTT24 you have a portable all-in-one measuring device for fast precision signals that can be expanded to a stand-alone system if required.
