通常Normal trigger 與 Auto trigger最容易讓人混淆,因為像弦波、方波等週期性的波形,在這兩種trigger mode中,不會有timeout的機會,都能夠以波形觸發,因此使用起來感受是相同的,這也是大部分人對於這兩種trigger mode混淆的原因。所以只有當你在面對久久出現一次的故障訊號時,Normal trigger才會對你有意義,因為它會將...
Complete trigger: Trig mode: Auto/Normal; Trigger types: Rise/Fall, Trigger level: Manual/AutoVertical sensitivity and time base: The scope's vertical sensitivity is ranges from 10mV/div to 10V/div (1X ranges). The oscilloscope time base is ranges from 5ns to 10s.Waveform save: One-...
the jitter analysis. The oscilloscope is run in histogram mode with a time-window size of 200 ps, providing high temporal resolution at a sampling rate of 20 GHz. The oscilloscope provides a built-in function for jitter measurement and allows for true picosecond histogram resolution. The os...
In practice most designers choose to add an explicit capacitor in this location to improve tolerance to small changes in layout, such as may occur when connecting oscilloscope probes. Ensure the time constant for the divider does not extend over many switching cycles. This limitation ensures that ...
Check inverter outputs U, V, and W using an oscilloscope with respect to the inverter GND, while taking care of scope isolation requirements. This ensures that the inverter is working properly. CAUTION After verifying this, take the controller out of real time mode (disable), reset the ...
PWM_VALUE it is possible to set the CCR 4 equal to CCR A plus the delay and set a falling ADC External trigger In this way, supposing that the sampling point must be set before the counter overflow, that is, when the TIM1 counter value matches the OCR4 register value during the up ...
During LPCD and ULPCD, a host microcontroller (if attached) can be set to power-saving mode as no host controller interaction is required. A low-frequency timer is implemented to drive a wake-up counter, which triggers a periodic activation of the antenna drivers to emit a short pulse. ...
After the probe pulses are separated from the system photons, they shine on a low-noise amplified photon detector and the waveform is sampled by a 12-bit (4096 level) full HD oscilloscope working in the external trigger mode. The system photon exits the PSI from another port and is then ...
Using a high-bandwidth oscilloscope, it is found that the output-pulse width as 1.4 ns at full width half maximum for these detectors of 2×40 μm length by using low-noise amplifiers with small low frequency cut-off values which cause only minor output voltage overshoot. Operation in the ...
A conventional photodetector64detects the split-off light pulses from beam splitter62and provides an output signal that triggers oscilloscope71to acquire the signal from power amplifier70. A CCD video camera72takes a picture of the screen of oscilloscope71, which is then downloaded to a computer73...
