Displays the Triggering Source Menu.

Used when External or Video buttons are activated. Measurement begins after set time delay once the trigger has occurred. The delay can be entered either as a percentage of the sweep time or as an absolute time delay with units of ns, μs or ms.

A negative delay displays the trigger position on screen, while a positive value places the trigger point off the screen to the left.

Used when External or Video buttons are activated. Sets a level trigger to initiate a measurement.

Sets the trigger slope to rising or falling.

When used, value unit is in dB. Hysteresis can be used with Level and Slope when setting a measurement trigger. Hysteresis is used to prevent undesired triggering when the signal is hovering near the trigger value. For example, the Level is set to 10 dBm, the Slope is set to Rising, and Hysteresis is 1 dB. The first trigger occurs when the signal at least reaches the 10 dBm level. To trigger again, the signal must drop below 9 dBm before returning to 10 dBm. For another example, with Level set to 10 dBm and slope set to Falling, and Hysteresis set to 1 dB, the opposite must occur to activate a trigger. The signal amplitude falls and a trigger occurs when the signal reaches the 10 dBm level. The signal must then reach at least 11 dBm before falling to 10 dBm and initiating a trigger.

Delays the next trigger to the time set regardless of triggers occurring within the set time.

Forces a sweep regardless of meeting any trigger criteria.
