In order to control the USB series high-speed data acquisition card, the acquisition card set a lot of advanced triggering functions, multi-channel oscilloscope software provides a convenient trigger properties dialog box. It allows you to view and set all properties of a trigger, such as trigger source, trigger type, all levels and lags, and optional time conditions. In addition, this article describes the types of triggers you select and examples that do cause triggers (left column) and do not cause triggers (right column).

Introduced
HS Series USB High-speed data acquisition card with a set of high-and data-system software.

The hardware part of the acquisition card is equipped with a trigger circuit, which is convenient to start the measurement when certain conditions appear in the input signal. Triggering is used both to capture unique signal events and to stabilize the display measurement of repetitive signals. In the absence of a trigger, the signal is randomly collected for measurement and display. Trigger circuit has a variety of settings, divided into the Instrument trigger settings and channel trigger settings two.
Instrument Trigger Settings
This part is the instrument trigger setting. These settings affect the entire instrument, and the channel trigger settings affect only one channel of the instrument.
Trigger Source

Several different trigger settings are available to determine how the system will trigger the signal. The trigger source setting of the instrument determines the trigger signal used to trigger the instrument.
The trigger source can be set to any combination of a single channel or channel or other trigger source. You can use the or function to logically combine sources. In the image below, the trigger source is set to CH1 or EXT1.
When no trigger source is selected, the triggering system is disabled and the instrument runs freely: it will begin to measure the sample directly.

Change the trigger source

Changing the trigger source of an instrument in a multichannel oscilloscope software can be done in a variety of different ways:
Open the Trigger Properties dialog box and use the source selector to select the trigger source you want. The advanced option provides the possibility to set multiple trigger sources for a combination.
Trigger Source
Channel Trigger
The channel can be used as a trigger source. Channel triggers can be configured by trigger type, trigger level, trigger lag, trigger condition, and trigger condition time properties.
Digital external
In addition to the normal input channel triggers, most engineering instruments have external trigger inputs that can be used to connect external digital trigger signals. You cannot set trigger level and lag for this trigger input, but you can set the edge (up or down) that the system should respond to.
Generator Trigger

Handheld oscilloscope HS5 and handheld oscilloscope HS3 are equipped with arbitrary waveform generators. The generator has an internal trigger signal that can act as a trigger source:
Generator start
This signal is generated when a continuous or burst generation is started through a Start button or an external trigger signal.
Generator new Cycle
The signal is processed at the entire buffer of the arbitrary waveform generator and the arbitrary waveform generator is generated again at the beginning of the buffer.
Generator shutdown
This signal is generated when the stop button stops continuously generating a burst build, or when a burst generation is stopped due to the number of cycles required to generate.
Pre-trigger/pre-sampling
Using a digital storage oscilloscope, the recording length determines the number of samples to be measured. All of these samples can be measured after the trigger has occurred. However, by selecting pre-sampling, you can measure a portion of the record before the trigger occurs.

Front and rear samples

The total records are then divided into pre-trigger and post-trigger sections, respectively, with pre-and post-sampling. This approach is possible "retrospective time" because samples are captured before the triggering time.
With the Tipipe engineering instrument, the trigger torque can be defined at any location in the record.
Changing the trigger torque in the multi-channel oscilloscope software can be done in a variety of different ways:

Reduce pre-sampling and increase pre-sampling on the Instrument toolbar by clicking the increase/decrease pre-trigger percentage button.
Trigger hold
When pre-sampling is selected, the system is triggered until the measured number of samples is activated until the measurement is started. This number of samples is called Trigger hold. When the input signal satisfies the triggering requirement during the trigger hold, no trigger is generated and the system keeps sampling pre-sampling. After the triggering delay has elapsed, the system will start the measured post-sampling when the trigger condition is met for the first time. This will ensure that at least a specified number of pre-samples will be measured.
Trigger delay:
Trigger delay allows you to start measuring the specified time after the trigger has occurred. This allows you to capture events that exceed a full record length over the trigger time. Changing the trigger delay in the multi-channel oscilloscope software can be done in several ways:
Trigger condition
Several oscilloscope channel trigger types can have additional trigger conditions and corresponding trigger condition times. Some trigger conditions have two trigger times, which define the trigger condition timeframes. The following trigger conditions are available:
Trigger timeout
Once the trigger condition is set and the measurement is started, the instrument waits until the trigger condition is met, then measures the sample and completes the measurement.
The instrument will wait forever if the trigger condition is set in such a way that the input signal never satisfies the trigger setting. When no measurement is performed, the signal is not displayed.
to prevent the system from waiting indefinitely, the triggering timeout is added to the triggering system. The trigger time-out forces the trigger when the amount of time after the user-defined start measurement still does not have a trigger to occur. This ensures a minimum number of measurements per second. On a traditional desktop oscilloscope, this is called the trigger mode automatically, with a value of approximately 20 milliseconds.
Brute force:
In addition to using the available trigger sources and triggering timeouts to start the measurement, you can also stop waiting for the trigger time and start the measurement after sampling immediately by forcing the instrument to trigger. The
Channel trigger setting
Channel trigger circuit continuously monitors the channel and generates a trigger signal when the input signal satisfies a certain predefined trigger condition. To change this situation, multiple channel trigger settings can be used, and all channels can be adjusted independently. The

Trigger type

There are several different types of triggers:
The trigger type describes the
rise, fall, or edge trigger trigger of any edge
when the signal enters or leaves a window or range, the window triggers the trigger, optionally shorter/longer than the specified time. The
triggers a trigger on the pulse width of a positive or negative pulse in a signal that is wider or narrower than the specified width, or on the internal/external
of a specified timeframe to change the trigger type of the channel in the multichannel oscilloscope software in a variety of different ways:
Touch generation Flat
All oscilloscope Channel trigger types use one or two-touch generation level. You can set the power level individually for each channel. The trigger level is set in absolute or relative value, depending on the selected touch-generated flat mode. In multi-channel oscilloscope software, the change of the touch-level of the channel can be done in several ways
drag/move the trigger symbol (rising edge symbol, falling edge symbol, etc.) on the axis of the oscilloscope channel used as the trigger source. The trigger level can be changed by moving the edge of the symbol associated with the level, or by moving the entire symbol.
Trigger lag
All oscilloscope channel trigger types use one or two trigger lags. Hysteresis defines the distance between the firing level and the disarm level, and determines the sensitivity of the triggering system. A small lag means that the disarming and firing levels are close to each other, and a small signal change will be sufficient to trigger the triggering. A large lag means that the signal must change greatly before the trigger is triggered. This makes the triggering system less sensitive to noise.
Trigger condition
Several oscilloscope channel trigger types can have additional trigger conditions and corresponding trigger condition times. Some trigger conditions have two trigger times, which define the trigger condition timeframes. The following trigger conditions are available: The
Trigger condition time (s)
Trigger condition time Specifies the duration, in seconds, for a particular signal condition. When two trigger condition times are available, two times the trigger condition timeframe is defined, in seconds. More triggers see: www.pc17.com.cn
