Operation with the R&S NRP power meter
Connecting the power sensor
The power sensor can be connected to the R&S NRP base unit when it is in operation. The multiple
circular plug-in connector must be inserted, red marking upwards, into one of the R&S
NRP base unit’s
sensor connectors. When the power sensor is connected, it is detected by the R&S NRP base unit and
initialized.
See Table 1-1 for the type of male RF connector a certain power sensor has and which female
connectors it mates with. Using light pressure, and keeping the male connector perpendicular, insert it
into the female connector and tighten the locking nut (right-hand thread). In many cases, the RF
connector only requires manual tightening. However, for maximal measurement accuracy, the RF
connector must be tightened using a torque wrench with a nominal torque that corresponds with the
tightening torque shown in Table 1-1.
