The available trigger levels depend on the RF attenuation and preamplification. A refer-
ence level offset, if defined, is also considered.
For details on available trigger levels and trigger bandwidths, see the data sheet.
Remote command:
TRIG:SOUR IFP, see TRIGger[:SEQuence]:SOURce on page 123
I/Q Power ← Trigger Source
This trigger source is only available in the I/Q Analyzer application and in applications
that process I/Q data.
Triggers the measurement when the magnitude of the sampled I/Q data exceeds the
trigger threshold.
The trigger bandwidth corresponds to the bandwidth setting for I/Q data acquisition.
(See " Analysis Bandwidth " on page 59).
Remote command:
TRIG:SOUR IQP, see TRIGger[:SEQuence]:SOURce on page 123
RF Power ← Trigger Source
Defines triggering of the measurement via signals which are outside the displayed
measurement range.
For this purpose, the instrument uses a level detector at the first intermediate fre-
quency.
The input signal must be in the frequency range between 500 MHz and 8 GHz.
The resulting trigger level at the RF input depends on the RF attenuation and preampli-
fication. For details on available trigger levels, see the instrument's data sheet.
Note: If the input signal contains frequencies outside of this range (e.g. for fullspan
measurements), the measurement may be aborted. A message indicating the allowed
input frequencies is displayed in the status bar.
A "Trigger Offset" , "Trigger Polarity" and "Trigger Holdoff" (to improve the trigger stabil-
ity) can be defined for the RF trigger, but no "Hysteresis" .
Remote command:
TRIG:SOUR RFP, see TRIGger[:SEQuence]:SOURce on page 123
Time ← Trigger Source
Triggers in a specified repetition interval.
Remote command:
TRIG:SOUR TIME, see TRIGger[:SEQuence]:SOURce on page 123
Trigger Level
Defines the trigger level for the specified trigger source.
For details on supported trigger levels, see the data sheet.
