Trigger In ← Mode
The connector is used as input. An external trigger signal can be applied.
Fig. 4-88: I/O 2 mode / Trigger In
Use the external trigger signal, e.g. to start the measurement in all sensors simultane-
ously. Provided the R&S NRP2 is configured accordingly, it passes the signal directly
through to the sensors. Refer to chapter 4.2.6, "Trigger settings", on page 85 for infor-
mation on the respective settings.
Remote command:
The state must be set to
OFF.

4.7.2.3 Voltage at the analog outputs
The voltage at the analog outputs does not track the power fed to the sensor continu-
ously but rather at discrete points of time. Every time the sensor has transmitted a new
measured value to the base unit, i.e. after an aquisition has been completed (chap-
ter 4.2.3, "Filter / averaging", on page
79), the analog output voltage is adjusted to the
new value.
In the ContAv mode, you can influence the rate at which the voltage is updated by set-
ting the aperture time to a convenient value, see chapter 4.2.1.2, "Continuous average-
power measurements",
on page 66. The time between two updates of the output volt-
age is approximately twice the length of the aperture time. The lower limit of this length
