Repetition Mode
Single-shot: The measurement is stopped after the number of measurement intervals
defined by the "statistic count".
Continuous: The measurement is continued until it is stopped explicitly. Average results
are calculated according to the rules given in section Statistical Results.
Manual and remote control
In contrast to other instrument settings, the repetition modes in manual and remote con-
trol are independent and do not overwrite each other. The default repetition mode in
manual control is Continuous (observe results over an extended period of time), the
default mode in remote control is Single-Shot (perform one measurement and retrieve
results).

Statistics Type
In general the following types of statistical results are available for scalar results (single
values) and traces:
Current: Result of the current measurement interval
Minimum/Maximum: Minimum or maximum of all evaluation periods since the mea-
surement was started
Average: Average referenced to one single-shot measurement length

Detector
Some measurements provide different detector settings to calculate the returned results
from the raw measurement data. An example is the GPRF Power measurement which
evaluates the maximum, minimum, and RMS (average) power within the current mea-
surement interval (see Detectors). The detector is identified by means of an additional
mnemonic preceding the statistics type:
FETCh:<FWA>:<Context>:<View>:CURRent?
FETCh:<FWA>:<Context>:<View>:MINimum:CURRent?
FETCh:<FWA>:<Context>:<View>:MAXimum:CURRent?
