E-3
[SENSe[1..4]]:FUNCtion[:ON][?] <string>
This command sets the sensor to one of the measurement modes of
Table 6-11
.
Table 6-11: Measurement modes
<string>
Measurement mode
"POWer:AVG"
ContAv
After a trigger event, the power is integrated over a time interval (averaging) set with
SENS:POW:APER
.
"POWer:TSLot:AVG"
Timeslot
The power is simultaneously measured in up to 26 time windows. The number of time windows
is set with
SENS:POW:TSL:COUN
. The length of a time window is determined via
SENS:
POW:TSL:WIDT
. The measurement result is represented by a vector that can contain
up to 26 indices and contains the power of a time window at each index.
"POWer:TGATe:AVG"
Timegate
The Timegate mode is a pseudo-mode. It is used to determine accurate measured values in
the gates defined with the aid of the Scope mode in manual operation. If one of the four gates
is selected (
SENS:TRAC:SEL
), the sensor is internally put into the Timeslot mode and
configured such that it determines the average power in this gate with high accuracy.
"POWer:BURSt:AVG"
Burst
In remote control, this measurement mode is very similar to the ContAv mode. The integration
time is, however, 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 the set trigger level.
The end is set when the signal drops below the trigger threshold.
SENS:POW:BURS:DTOL
defines the time interval during which a signal drop below the trigger level is not interpreted as
the end of the burst. In the Burst mode, the set trigger source is ignored and
TRIG:SOUR
INT
is implicitly assumed.
"XTIMe:POWer"
Scope
A sequence of measurements is performed. The individual measured values are determined as
in the ContAv mode. The length of an individual measurement is determined from the ratio of
the total time (
SENS:TRAC:TIME
) and the number of individual test points
(
SENS:TRAC:POIN
).
In remote control, the timing (
SENS:TIM:EXCL:STAR
and
-:STOP
) and the trigger system of all
measurement modes (except the Burst mode) are user-selectable.
Note:
To increase measurement accuracy, the sensors measure each signal
twice in the Burst, Timeslot and Scope measurement modes (exception: in
the Scope mode, with
SENS:TRAC:REAL ON
). As long as the trigger
system is set to internal or external triggering, this is usually of no
importance to the user. If
TRIG:SOUR HOLD
or
BUS
is used, however, then
each measurement must be triggered twice (with
*TRG
or
TRIG:IMM
).
