Real-Time Saving to SD Card in High Resolution CAN Signal Measurement for Vehicle Testing Multi-Channel Mixed Measurement of Various Signals Touch Screen for Direct Operation Analyze Data with a Variety of Intelligent Functions
1 Real-Time Saving to SD Card in High Resolution rate with a high resolution of 25,000 point f.s. The same working principle as that of a digital oscilloscope is used to Input A/D conversion Isolation 25,000 point Collect physical signals at a 500kS/s sampling record data to the large-capacity internal memory at high speed. The sampling rate is 500 kS/s (2 μs period) on all channels simultaneously. Sensor signal waveforms are recorded and represented faithfully.
2 CAN Measurement for Vehicle Testing Synchronized mixed recording of CAN data and real data such as voltage, temperature, or distortion signals CAN bus signals that are used widely, particularly in automotive applications, can be recorded, analyzed, converted to analog waveforms, and viewed. Simultaneous recording and viewing of analog waveforms from sensors, in addition to the CAN data, allows for checking the impact of noise and level changes on the communication data.
3 Multi-Channel Mixed Measurement of Various Signals Install your input modules according to your n Support for various measurement items (Using the optional input unit, and the optional differential probe for AC RMS voltage) specific needs Measurement target The plug-in units use an input amplifier structure and can be selected according to your measurement application. Additional input modules Voltage can be purchased separately and switched with existing units.
4 Touch Screen for Direct Operation Touch screen interface improves operating efficiency Buttons on the main body are kept to a minimum by utilizing touch screen technology. The high-definition 8.4-inch high-brightness TFT color LCD is the interface of choice for improving productivity by offering a more intuitive experience than traditional input methods.
5 Analyze Data with a Variety of Intelligent Functions Split screen, sheet display, event mark input, and jump functions indispensable for efficient analysis Split screen and sheet display functions are provided to support multiple channels. Individual display formats can be selected and an application can be assigned to each sheet for analysis, increasing productivity. ★ For long-term recordings, tag important points with event markers.
Measure the displacement-pressure relationship of a press machine or the pressure-flow rate of a pump Not only time-axis waveforms but also X-Y waveforms can be viewed. This function is also useful for collecting mechanical data, because X-Y Lissajous waveforms such as those of displacement, pressure, and flow rate can be drawn.
