Setup External Device Connection to the Aux unit(s) on the Main unit.
This step configures the IP address of the external devices and other connection related parameters to ensure a valid connection. For the detailed manual operation, see Step 1: Setup Main-to-Aux Connection on the Main Unit .
High Level Setup for the Main unit.
This step configures the test application parameters. For the detailed manual operation, see Step 2: Main Unit High Level Setup .
Automatic Multi-carrier Setup
This step performs the most setups for MCMU configuration. The function `Execute Automatic Setup' is provided to perform a series of necessary setups orderly and automatically. You can either perform the function `Execute Automatic Setup' which will automatically perform Step 3a - Step 3e in MCMU Automatic Setup Steps , or you can individually perform each of the Step 3a - Step 3e. For the detailed setups in this step, see Step 3: Multi-carrier Automatic Setup .
Traffic Configuration, Open a Session and Connection
This step configures the test sets as needed for measurements and other testing (channel configurations, connection, etc.). For the detailed manual operation, see Step 5: Traffic Configuration, Open a Session and Connection
Note that you can only setup settings that are associated with signaling with the AT on the Main unit. However you can setup settings that are not associated with signaling with the AT on each unit independently as desired. For the related settings, see Multi-carrier Parameters Setup Consideration .
This step configures and performs specific measurements on each unit independently. For the detailed manual operation, see Step 6: Configure and Perform Measurements on Each Unit
This step disconnects the Main unit with the Aux unit(s). For the detailed manual operation, see Step 7: Multi-carrier Multi-unit Disconnection
You can either perform Automatic MC Setup Execute, which will automatically perform Step 3a - Step 3e in the table below, or you can individually perform each of the Step 3a - Step 3e. The table below shows the detailed setups performed on the test sets orderly and automatically when Execute Automatic Setup is selected, see Step 3: Multi-carrier Automatic Setup for the manual operation.
Multi-unit operation brings about a unique feature to the settings that some settings are shared between multiple units, some settings are set on one unit but also control other unit(s), some settings are unit-independent, and some settings are out-of-scope. The specific behavior is based on Local Testset Configuration configuration.
When configuring a multi-carrier setup, several issues should be considered: setting up the connection and session, setting up for individual carriers, and the general test set configuration (e.g. measurement setups), which will involve setting on the Main unit and/or on the Aux unit(s).
Settings that are allowed to be set or shown differently on each unit (carrier dependent) and involve Over-The-Air signaling with the AT will be set on the Main unit for all carriers.
Take the parameter of `R-Data Packet Size in "Aux Carriers Info" and the result of `Channel Connected Status' in the Active Cell status area for example, The table below shows how the settings interacted between the Main unit and the Aux units, where the arrow indicates the setting value `pushed' from the Main unit to the Aux unit(s) and the `*' indicates that the setting is out of scope on that unit.
Settings that are allowed to vary between carriers (carrier dependent) but do not involve signaling with the AT will be set on the unit associated with that carrier. On each unit, you can configure these settings for the carrier that is being generated by that unit. The related setups include: measurement related setups and initiations/queries, settings that are not specifically carrier depended but are allowed to vary between test sets.
