Measurement Length ← Inner Loop Power
Displays the number of slots to be measured in "Inner Loop Power Control" mode. The
value depends on the selected TPC setup and the test step settings.
Remote command:
TPC Auto Execute ← Inner Loop Power
This parameter is only available while the combined signal path scenario is active.
If it is enabled, starting or restarting the measurement in measurement mode "Inner
Loop Power Control" triggers the execution of the TPC setup by the signaling applica-
tion.
Remote command:
TPC Test Step Settings ← Inner Loop Power
The table lists settings for the individual inner loop power control test steps.
Test steps A, B, and C are defined by 3GPP. The corresponding TPC bit patterns are
fixed and the number of TPC bits per step is displayed as "Length".
For test steps E, F, G, and H the number of TPC bits per test step is configurable.
Example: "Test Step E,F" = "120 Bit" means that 120 zero bits are sent for step E and
120 one bits for step F, resulting in a measurement length of 241 slots for test step EF,
so that all power steps are measured. While the combined signal path scenario is
active, these parameters are controlled by the signaling application.
The second column defines the number of slots at the end of a test step, where the
minimum output power or maximum output power results are measured. Example: 120
bits and 20 slots are defined for test step E. That means that 121 slots are measured
for the test step and the last 20 slots of these 121 slots are used to measure the mini-
mum output power.
For the test steps E, F, G, and H segmentation can be enabled via a checkbox. If you
use the WCDMA signaling application (combined signal path), the setting is controlled
by the signaling application. If you use the WCDMA generator, enable/disable the
checkbox so that it is compatible to the WCDMA generator settings. For any other
standalone scenario, disable the checkbox.
In the Standalone (SA) scenario, these parameters are controlled by the measurement.
In the Combined Signal Path (CSP) scenario, they are controlled by the signaling appli-
cation.
