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.
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.
