age1439_trigger_adclevel specifies the trigger threshold for an ADC trigger age1439_trigger_adclevel_get gets the ADC trigger threshold age1439_trigger_delay specifies a pre- or post-trigger delay time age1439_trigger_delay_get gets the trigger delay time age1439_trigger_gen determines whether a module can generate a trigger age1439_trigger_gen_get gets the trigger generation status age1439_trigger_magdwell specifies the wait (in samples) before transition causes

trigger

age1439_trigger_magdwell_get gets the number of dwell samples

age1439_trigger_maglevel specifies the trigger threshold for a magnitude trigger age1439_trigger_maglevel_get gets magnitude trigger threshold age1439_trigger_slope selects a positive or negative trigger age1439_trigger_slope_get gets trigger slope

age1439_trigger_type determines the trigger type age1439_trigger_type_get gets trigger type

Description

An Agilent E1439 can be triggered to collect data in a variety of ways. The trigger can be internally generated or can come from an external source. Multiple modules can be triggered synchronously. A variable pre- and post-trigger delay can be programmed for data collection. The slope and level of the trigger point on a signal can be selected. The source of the internal trigger can be either the output of the ADC or the magnitude of the complex output of the decimation filter.

age1439_trigger_setup is the function that sets all trigger parameters at once. An Agilent E1439 generates a trigger only when it is in the Trigger state and the Sync line on the VXI backplane is released. When a trigger is generated, the Agilent E1439 asserts the Sync line.
