OLTR: Results
The OLTR view shows the DUT's responses to the power down and power up steps of
a single OLTR measurement sequence. The responses are recorded as power vs.
time traces, with power values (in dB) relative to the corresponding reference power
level. The direction of the first power step is displayed above, the reference power of
both steps is displayed below the diagrams. The red lines represent the response corri-
dor specified as minimum standard in 3GPP2 C.S0011. Limit violations in particular
time interval are indicated underneath the time axis.
Fig. 5-18: CDMA2000 OLTR Measurement: One Measurement Sequence
Each step trace consists of 60 equidistant values for the reference power interval, 640
equidistant values for the OLTR evaluation interval and 20 equidistant indicators of the
OLTR limit violation.
5.2.9 Common Elements of Views
Below the title bar, all views show the most important RF and analyzer settings as
shown below; see
Signal Routing and Analyzer Settings
.
Tables
Most detailed views show tables providing a statistical evaluation of results. Diagrams
and tables are related to the same time interval of the signal. The statistical values in
the tables are calculated as follows:
●
Current:
Value of the result obtained in the last measurement interval. For some
modulation results the current RMS value (the average over all samples) and the
current peak value (the peak of all samples) is available.
