11.3 Explanation of measurement result
display
When you start the measurement, the SRM-3006 searches through the
specified UMTS frequency channel for scrambling codes and measures the
associated field strengths. It also makes an analog measurement of the total
power level of the UMTS frequency channel. The sections below explain the
various measurement results that are displayed.
11.3.1 Individual results
The
Scr
column successively shows the numbers of the scrambling codes
that are detected (numbers between 0 and 511), sorted in ascending order
and numbered consecutively in the
Index
column. The list can contain up to
16 scrambling codes.
Note:
If no scrambling code is detected, the message
No Scr. Code found
is displayed. This could be due to the center
frequency Fcent not being set correctly.
Fcent must be set to an
exact multiple of 100 kHz.
The
Act
column shows the actual measurement results for each scrambling
code multiplied by the extrapolation factor (Extr. Fact.).
The remaining columns show the selected result types (Result Type), e.g.
the maximum, average, and minimum values that occurred since the start of
the measurement, multiplied by the extrapolation factor (Extr. Fact).
The maximum and minimum values can be cleared using the Result Type /
Reset Min & Max softkeys. The entire table can be cleared using the
Result Type / Table Reset softkeys. You can clear the scrambling codes no
longer received from the list in this way to make room for new ones.
Note:
Any change in parameters resets the entire table (same as
Reset All).
11.3.2 Total result (Total)
This value corresponds to the total power of all the scrambling codes listed,
multiplied by the extrapolation factor (Extr. Fact.). A total result is determined
from both the instantaneous and maximum individual results.
