M
Press the "Display Settings" softkey.
M
Select the "Slot Number…" menu item.
The R&S FSH opens an input field to select the slot.
M
Enter the number of the slot you want to analyze.
In the code domain power result display, the numerical results that the R&S FSH
displays belong to one code channel only. By default, the R&S FSH shows the results
for the first code channel (which is always the pilot channel).
M
Press the MEAS key.
M
Press the "Display Settings" softkey.
M
Select the "Code Channel…" menu item.
The R&S FSH opens an input field to select the code channel.
M
Enter a number between 0 and 511 to select a particular code channel.
If you select a code that is part of a channel made up of more than one code, results
correspond to the channel, not the one code.
7.2.4.4 Changing the Code Power
By default, the application displays the absolute power of all code channels.
Alternatively, you can display the power relative to the P-CPICH.
M
Press the MEAS key.
M
Press the "Power Settings" softkey.
M
Select the "Relative to CPICH" menu item.
All power display now relate to the pilot channel.
7.2.4.5 Performing Fast Measurements
Faster measurements are possible if you skip the channel search during the
measurement.
M
Press the MEAS key.
M
Press the "Signal Settings" softkey.
M
Select the Channel Search Off menu item.
The R&S FSH stops performing a channel search.
If the channel search is off, measurements are faster. However, some results, like the
Composite EVM, can not be calculated if the channels are not known. Thus, turning
the channel search off is useful if you are interested in signal powers only.
The channel search is always on for the Code Domain Power and Code Domain
Channel Table result displays. All other result displays work both ways.
