Advantages of the vibration testing performed by the Yokogawa oscilloscope recorder DL850E in accordance with the requirements for testing automotive relays

Thread Content

　　The vibration testing capabilities of the Yokogawa oscilloscope recorder DL850E, in line with the requirements for testing automotive relays, offer the following 4 advantages: 1. A maximum storage depth of 2G and a 500G hard drive enable ultra-long-term data recording, allowing all voltage waveforms from the entire testing process to be captured. 　　2. The dual-capture function allows us to collect signals in their normal state over a long period of time at a relatively slow sampling rate; when an error occurs, it is possible to sample the sudden, high-speed abnormal signals at a rate as fast as 100 MS/s. This way, both high-speed and low-speed signals can be captured using these two different sampling rates. By analyzing the waveforms of the dual capture lists, it is possible to obtain the waveform of the malfunction, the voltage, and the duration of the malfunction. 　　3. The trigger function enables unattended operation, allowing the oscilloscope recorder to record the waveforms of interest in each testing process through triggering. 　　4. Edge or trigger function, allowing us to measure multiple relays simultaneously.
