Used KEITHLEY 150740 #9293219 for sale

KEITHLEY 150740 is an electronic test equipment designed to measure low-level pulse width modulated (PWM) signals with maximum resolution and accuracy. This device enables users to accurately characterize the behavior of pulse width modulated (PWM) signals, such as digital waveforms, without the need to connect external instrumentation. The device consists of two stages, a pulse width analyzer and a digital oscilloscope. The pulse width analyzer consists of a simple circuit that utilizes a sample and hold circuit, along with a comparator to detect the PWM signal's duty cycle and output a pulse signal of the same duty cycle. The output is connected to a single-shot A/D converter, which is used to convert the pulses into digital data. The digital data is then read by the digital oscilloscope, which displays graphically the duty cycle, frequency and amplitude of the waveform. The digital oscilloscope is capable of activating an alarm whenever the duty cycle exceeds the configured limits. 150740 also provides several useful features for troubleshooting and analyzing PWM signals. The device has a trigger input port that allows the user to synchronize the scope to specific transitions on the waveform to make measurements easier. It also features real-time data display capabilities and frequency response analysis functions for digital waveforms. In addition, an optional memory card can be used to store up to 40 seperate test results. KEITHLEY 150740 is a versatile and reliable piece of electronic test equipment that is well suited for engineers and technicians who need to accurately measure and characterize low-level pulse width modulated (PWM) signals. With its high resolution and accuracy, it is a great choice for creating detailed and comprehensive data that can help troubleshoot and analyze PWM signals.
