Signal attenuation is the degree of signal amplitude contraction after passing through an attenuator device (probe or attenuator). Signal attenuation is determined by the input signal to output signal ratio. For example, 10X probe attenuates (reduce) the input signal voltage by 10.
Root of the root mean square deviation from the average value on all periods obtained on the specified area.
It is a rise time trigger, fall time trigger or both. Input signal trigger, the signal goes between two thresholds for the time which is more or less then the specified value; within or beyond the specified time interval.
Trigger is a synchronization event which sets zero reference time value in the signal registration in digital oscilloscopes.
Trigger coupling can be chosen depending on the signal type used for oscilloscope synchronization. There are several coupling types acceptable.
Trigger delay is a specified time interval after the trigger moment when the trigger system doesn’t take any other trigger signals. Trigger delay provides the stability of the signal image.
Trigger level is threshold voltage value the exceeding of which leads to a registration trigger signal forming in digital oscilloscopes.
The trigger mode determines the starting of recording (data collection) order in oscilloscope. Articles 91 - 100 of 118 First | Prev. | 8 9 10 11 12 | Next | Last |
