Interval trigger or period trigger allows triggering on a periodical signal with a period time shorter or longer than a specified time or inside or outside a specified time frame. To trigger on the signal, the scope uses two levels to determine the flanks of the signal the same way as rising and falling edge triggers.
The trigger condition parameter determines whether the interval time must be shorter than or longer than a trigger condition time parameter, or inside our outside a trigger condition time frame to cause a trigger.
Interval (rising)
When using Interval (rising) triggering, the system triggers when the input signal contains a periodical signal starting with a rising edge that crosses both levels, in upward direction.
When one of the levels is not crossed, no trigger occurs.
Interval (rising) Shorter than
When using condition Shorter than in combination with Interval (rising) triggering, the system will trigger when the signal is periodical, starting with a rising edge and exceeding both levels, having a period time shorter than the specified time. The time interval starts as soon as the leading edge of the period is detected.
When the period time is longer than the specified time, or one of the levels is not crossed, no trigger occurs.
Interval (rising) Longer than
When using condition Longer than in combination with Interval (rising) triggering, the system will trigger when the signal is periodical, starting with a rising edge and exceeding both levels, having a period time longer than the specified time. The time interval starts as soon as the leading edge of the period is detected.
When the period time is shorter than the specified time, or one of the levels is not crossed, no trigger occurs.
Interval (rising) Inside
When using condition Inside in combination with Interval (rising) triggering, the system will trigger when the signal is periodical, starting with a rising edge and exceeding both levels, having a period time that is inside a specified time frame. The time intervals start as soon as the leading edge of the period is detected.
When the period time is shorter or longer than the specified time frame, or one of the levels is not crossed, no trigger occurs.
Interval (rising) Outside
When using condition Outside in combination with Interval (rising) triggering, the system will trigger when the signal is periodical, starting with a rising edge and exceeding both levels, having a period time shorter than or longer than a specified time frame, in other words outside a specified time frame. The time intervals start as soon as the leading edge of the period is detected.
When the period time is within the specified time frame, or one of the levels is not crossed, no trigger occurs.
Interval (falling)
When using Interval (falling) triggering, the system triggers when the input signal contains a periodical signal starting with a falling edge that crosses both levels, in downward direction.
When one of the levels is not crossed, no trigger occurs.
Interval (falling) Shorter than
When using condition Shorter than in combination with Interval (falling) triggering, the system will trigger when the signal is periodical, starting with a falling edge and exceeding both levels, having a period time shorter than the specified time. The time interval starts as soon as the leading edge of the period is detected.
When the period time is longer than the specified time, or one of the levels is not crossed, no trigger occurs.
Interval (falling) Longer than
When using condition Longer than in combination with Interval (falling) triggering, the system will trigger when the signal is periodical, starting with a falling edge and exceeding both levels, having a period time longer than the specified time. The time interval starts as soon as the leading edge of the period is detected.
When the period time is shorter than the specified time, or one of the levels is not crossed, no trigger occurs.
Interval (falling) Inside
When using condition Inside in combination with Interval (falling) triggering, the system will trigger when the signal is periodical, starting with a falling edge and exceeding both levels, having a period time that is inside a specified time frame. The time intervals start as soon as the leading edge of the period is detected.
When the period time is shorter or longer than the specified time frame, or one of the levels is not crossed, no trigger occurs.
Interval (falling) Outside
When using condition Outside in combination with Interval (falling) triggering, the system will trigger when the signal is periodical, starting with a falling edge and exceeding both levels, having a period time shorter than or longer than a specified time frame, in other words outside a specified time frame. The time intervals start as soon as the leading edge of the period is detected.
When the period time is within the specified time frame, or one of the levels is not crossed, no trigger occurs.
