This setting has no influence on "Free Run" measurements.
Remote command:
TRIGger:EVDO:MEAS<i>:MEValuation:TOUT
Minimum Trigger Gap
Defines a minimum duration of the power-down periods (gaps) between two triggered
power pulses. This setting is valid for an "(IF) Power" trigger source.
The trigger system is controlled by means of a timer which is reset to zero in the follow-
ing instances:
●
At the IF power-down ramp of each triggered or untriggered pulse, even though the
previous counter may not have elapsed yet. A power-down ramp is detected when
the signal power falls below the trigger threshold.
●
At the beginning of each measurement: The minimum gap defines the minimum
time between the start of the measurement and the first trigger event.
The trigger system is re-armed as soon as the timer has reached the specified mini-
mum gap.
The "Minimum Trigger Gap" can be used to prevent unwanted trigger events due to
fast power variations.
Remote command:
TRIGger:EVDO:MEAS<i>:MEValuation:MGAP
3.3.4 Multi Evaluation: Miscellaneous
This section describes the physical layer subtype setting.
Fig. 3-22: Multi evaluation configuration: physical layer subtype
Physical Layer Subtype
Selects the subtype of the physical layer protocol for the multi evaluation measure-
ments. The characteristics of the protocol subtypes are defined in specification 3GPP2
C.S0024.
The defined code channels and the evaluated parameters of the code channel filter
depend on the selected subtype, see also
