8 Trigger
8.1 Trigger
8.1.1.8 Audio External
When Audio External is selected, a new sweep/measurement starts when the
external trigger condition is met using the TRIG IN input connector on the front
panel of the M9260A Audio Analyzer module. This is a TTL level input (not analog)
that supports both rising edge and falling edge triggers.
Only appears in modular instruments, and only when the M9260A Audio Analyzer
module is installed, such as in M8920A.
The Trigger tab contains the following Trigger Source dependent controls when
Audio External Trigger is selected:
–
"Trigger Delay" on page 2461
–
"Trigger Slope" on page 2465
Additional controls are also present that are not dependent on the selected Trigger
Source.
Example
:TRIG:RTES:SOUR AEXT
Sets Audio External as the trigger source for the Radio Test measurement
Annunciation Audio Ext (in the Meas Bar)
8.1.1.9 RF Burst
When RF Burst is selected, a new sweep/measurement starts when an RF burst
envelope signal is identified from the signal at the RF Input connector.
In some models, a variety of burst trigger circuitry is available, resulting in various
available burst trigger bandwidths. The instrument automatically chooses the
appropriate trigger path based on the hardware configuration and other settings of
the instrument.
The Trigger tab contains the following Trigger Source dependent controls when RF
Burst is selected:
–
"Trigger Level Absolute/Relative" on page 2466
–
"Absolute Trigger Level" on page 2467
–
"Relative Trigger Level" on page 2467
–
"Trigger Delay" on page 2461
–
"Trigger Slope" on page 2465
