Product Features
High-speed sampling of 50 nsec to detect events (momentary breakdowns) without missing them
The comparator detects events (momentary breakdown) at 50 nsec sampling, writes event data to memory, and records events up to 1000 times/ch. The comparator detects both rising and falling resistance, allowing measurement of event width.
Resistance measurement as well as event (momentary breakdown)
The ED71 is capable of high-speed DC resistance measurement as well as event (momentary breakdown) detection. Resistance measurements can be made at intervals of 100 msec at the fastest. High-speed DC measurement is possible because all channels are equipped with independent measurement circuits instead of a scanner system.
Various external device interlocking functions
Combined with a thermal shock chamber, vibration tester, or drop tester, a wide variety of analyses can be performed by inputting external signals such as temperature, vibration frequency, and cycles. It is mainly used in combination with vibration machines in connectors for the automotive industry. (Event threshold: 7Ω / Event width: 1μsec or more)
| Name of equipment | entry | signal type |
|---|---|---|
| Thermal shock and temperature cycling chamber | Temperature | Communication, Thermocouple, Pt100 |
| Drop Testing Machine | cycle signal | No-voltage contact (drop tester side) |
| Repeated bending tester | cycle signal | No-voltage contact (Repeat bending tester side) |
| vibrator | Vibration frequency | 0-5V or 0-10V voltage (f/V conversion) |
High reliability of vent (momentary break) detection
The detection speed of an event (instantaneous breakdown) is greatly affected by the frequency characteristics of the power supply for application and the capacitance component of the measurement system. However, the ED71 uses an event generator manufactured in-house to evaluate event (momentary break) detection speed, taking into account the effects of the application and measurement systems, so it can be used with confidence.
operability
main screen
The main screen displays the status of each channel with a mark.
histogram
The recorded events (momentary breakdowns), resistance values, and vibration frequencies can be displayed graphically as shown in the figure below. You can see that events are occurring at specific frequencies and that they are resonating.
Progress graph
In addition to a progress graph, a histogram display is also available. The left graph shows that the resonance frequency is around 1230 Hz.
