Min Avg Minimum Average Minimum value of all averaged measurement
values.
MR Measurement Range The sensitivity of the system depends on the
input attenuator setting. This setting is
determined by the Measurement Range
parameter. High measurement sensitivity
avoids falsification of the results due to noise
generated internally by the device.
P-CPICH Primary Common Pilot

UMTS control channel.
RBW Resolution bandwidth Signal selectivity.
Only signals having a frequency spacing that is
greater than the defined resolution bandwidth
can be distinguished from one another. The
RBW selected for measuring signals having
very close frequency spacing must be
correspondingly small. A larger resolution
bandwidth can be used for measuring wideband
signals.
• The indicated level will be too low if the RBW
is too small.
• Individual signals cannot be separated from
one another if the RBW is too big.
Result Type Defines the way in which the measured values
are evaluated.
