Trigger holdoff is an adjustable period of time during which the digitizer cannot trigger. NI high-speed digitizers use trigger holdoff to guarantee a minimum time between two Reference Triggers.
The holdoff function in an oscilloscope is used to prevent the triggering circuit from re-arming immediately after a trigger event. This function adds a delay before the oscilloscope can trigger again, which can be useful for capturing complex or repetitive signals without triggering on unwanted events. It helps to ensure that the oscilloscope only captures the desired signal by allowing the user to set a minimum time interval before the oscilloscope can trigger again, ignoring any trigger events that occur during that time.
The trigger holdoff function in an oscilloscope delays triggering after each trigger event, preventing multiple triggers too close together in time. It helps stabilize the display of repetitive signals and avoids interference from noise or signal variations.
Dear Sir, Much appreciated your directions! Tektronics Oscilloscope (CRT) which I am having get defective. Kindly seek your directions to find the way of get repair it. Thank you!
The trigger holdoff function in an oscilloscope helps prevent multiple triggers from occurring too close together in time. It essentially delays the triggering mechanism for a specified time after each trigger event, ensuring that subsequent triggers aren't affected by noise or signal variations occurring shortly after the initial trigger. This feature is useful for stabilizing the display of repetitive signals and capturing distinct events without interference.
The comparison for multimeter and oscilloscope is not entirely correct. In fact, you can measure the current using an oscilloscope without an expensive current probe using a shunt resistor (just like the mechanism used by a multimeter). Of course this requires a ohm's law calculation to calculate the voltage, but modern oscilloscopes already have functions to set the reading to amperes. Similarly resistance and capacitance can also be measured indirectly, in fact the used oscilloscope that I have Beckman Industrial 9020 20Mhz, comes with a COMP Test, which can test diodes and resistors/continuity, by generating the IV characteristic waveform.
