●
Burst average (
"POWer:BURSt:AVG"
): The integration time of a measurement is
not predefined but determined by the sensor with the aid of a burst detector. The
start of a burst is detected when the measurement signal rises above a set trigger
level. The measurement ends when the signal drops below a trigger threshold.
See also
Chapter 8.7.2, "Burst Average Measurement" , on page 72.
●
Timeslot average (
"POWer:TSLot:AVG"
): The power is simultaneously measured
in up to 32 time slots. The measurement result is represented by a vector that can
contain up to 32 indices and contains the power of a time slot at each index.

Chapter 8.7.3, "Timeslot Average Measurement" , on page 74.
●
Trace (
"XTIMe:POWer"
): A sequence of measurements is performed.
See also Chapter 8.7.4, "Trace Measurement" , on page 76.
8.5 Controlling the Measurement
The power sensor offers a bunch of possibilities to control the measurement:
●
Do you want to start the measurement immediately after the initiate command or
do you want to wait for a trigger event?
●
Do you want to start a single measurement cycle or a sequence of measurement
cycles?
●
Do you want to output each new average value as a measurement result or do you
want to bundle more measured values into one result?

Immediately interrupts the current measurement. If the measurement has been started
as a single measurement (
INITiate[:IMMediate]
), the sensor goes into the idle
state. However, if a continuous measurement is in progress (
INITiate:CONTinuous
ON
), the trigger system of the sensor enters the waiting for trigger state, and if the trig-
ger condition is met, a new measurement is immediately started.
