Auxiliary trigger
The auxiliary trigger connector is located on the back panel of the vector network analyzer.
When the external source is configured as an external device, the vector network analyzer will
automatically control all trigger settings. Do not set other trigger settings. The vector network
analyzer will start measuring when it receives a valid trigger signal from the specified trigger
source:
•
Inside: Measurements begin immediately.
•
Manual: Press the vector network analyzer "Trigger" button to start the measurement.
•
External: The measurement starts when the measurement trigger input signal is received
from the external device. This must be configured separately.
The "Auxiliary Trigger Output" signal can be configured to be sent just before the
measurement is performed or just after the measurement is completed. When
communicating with an external source, the "Auxiliary Trigger Output" signal should be sent
after the measurement is completed to indicate that the external source can be set for the
next measurement.
Enable
: When checked, the signal can be output to external devices using auxiliary connectors.
•
Channel: This setting is controlled by the vector network analyzer “Preferences“ setting.
•
Global: All secondary trigger settings apply to all channels. On the Trigger Settings tab,
set the "Each Point" setting, which also applies to all channels.
Channels:
All secondary trigger settings will be applied to the specified channel and each
channel can be configured individually.
Auxiliary channel output (to device

The following settings control the properties of the signal emitted from the “Auxiliary Trigger
Output“ connector on the back panel:
Polarity:

Negative pulse: The output pulse is negative.
Location:
