Precision signal/function generator for the calibration and test of measurement chains and monitoring systems.The TSU151 precision signal generator is a two-channel signal/function generator using direct digital synthesis (DDS) for high resolution and accuracy.The TSU151, also known as a transducer simulator unit, is a multi-purpose instrument that generates voltage and charge signals over a wide range of frequencies to make calibration and testing easier and faster. With two digitally synthesised channels (outputs) capable of producing several types of signals, pulses and sweep functions, the TSU151 has the accuracy and flexibility to calibrate and test all types of measurement and monitoring system components from measurement chains to monitoring and/or protection systems such as VM600 and VibroSmart®.FeaturesVoltage (0 to 10 V PEAK) and charge (0 to 10000 pC PEAK) outputsSine, square, triangle and sawtooth signalsPulse (speed/ratio), single-pulse, odd-pulse and sweep functions40 memories to save and recall settingsBattery operated, compact and rugged
