Keysight launches Digital Storage Oscilloscope
The US-based Keysight Technologies, which manufactures electronic test and measurement equipment and software, has launched Digital Storage Oscilloscope (DSO). It is used to measure time and it has a protocol analyser. Keysight’s products include hardware and software for benchtop, modular, and field instruments. Keysight has been operating in India since 1999 and has presence in 6 cities: Manesar, New Delhi, Bangalore, Mumbai, Chennai and Hyderabad.
Electronic test equipment is used to create signals and capture responses from electronic devices under test. In this way, the proper operation of the DUT can be proven or faults in the device can be traced. Oscilloscopes are used to measure electric signals to display it as waveforms. Rather than processing the signals in an analog fashion, DSO converts them into a digital format using an analog to digital convertor (ADC). Since the waveform is stored in a digital format, the data can be processed either within the oscilloscope itself, or even in a PC connected to it. The trigger determines at what time should Oscilloscope start to acquire data and to a display a waveform. The trigger must set properly otherwise the waveform display may not stable and sometimes the screen goes blank due to synchronisation of trigger pulse. Digital storage oscilloscope is employed to measure: Voltage of the applied signal, Frequency of the applied signal, Time period of applied signal, Amplitude of applied signal, Average RMS value of applied signal, and Duty cycle of applied signal. During the testing time, they decode the signal and find out the errors in the time frame rate. Scope, power analyser, analyses the function of the power. This product measures the switching losses of the switching devices efficiently.
The company spokesperson said “the first stage the signal enters within the scope is the vertical amplifier where some analogue signal conditioning is undertaken to scale and position the waveform. Next this signal is applied to an analogue to digital converter (ADC). The DSO is easy to set up. The digital storage oscilloscope has many controls, e.g. Switch, TIME / DIV, Trigger controls, Intensity and focus, CH I and CH II inputs, VOLTS / DIV etc. Oscilloscopes can be used to measure and analyse the operating characteristics of power conversion devices, circuits, and line-power harmonics. It has the fastest update rates, the deepest memory, the industry’s only capacitive touch screen, and the most oscilloscope software options.”
Rapid technological advancements in the area of electric and hybrid electric vehicles will require comprehensive power tests for various in-vehicular systems designed for conversion of kinetic energy to battery energy. Stateof-the-art electric powertrain systems require comprehensive tests during development and test phases to ensure maximum safety and seamless operation before the vehicle goes on the roads.
Keysight provides high power test and measurement, from fuel cells to batteries addresses the mechatronics test needs – from the combination of electromechanical components, power electronics, micro-controller chips (e.g. engine control units or ECUs), to control software, ensuring only the best quality products move from the factory floors onto the roads. It also provides a range of powerful solutions to help automotive electronics designers and manufacturers optimise their design and development of cutting-edge battery and battery management systems, drivetrain motor control systems, electric motors and DC-DC converters.
