"Software"
Starts scheduling and data transmission/reception after a software trig-
ger.
"Ext. Trigger 1...3"
Starts the scheduling and data transmission/reception with an external
trigger signal. To supply the trigger signal use one of the GPIOs and
configure it accordingly in the "Hardware" tab.
"Basic Frame"
Starts scheduling and data transmission/reception with the next Basic
Frame. This corresponds to a free running trigger.
"Hyper Frame" Aligns scheduling and data transmission/reception to the next Hyper
Frame.
"Node B Frame"
Aligns scheduling and data transmission/reception to the next Node B
Frame.
"Sync Pattern"
Aligns the timing and data transmission/reception in the Rx path accord-
ing to a received sync pattern defined within a specified AxC. This trig-
ger mode requires that you have assigned "Sync Pattern" to one of the
signals.
Remote command:
Arm
Stops the data transmission, the scheduler and analysis. A subsequent trigger event
restarts the activities.
To select the trigger signal source, see
Remote command:

Example to CPRI Groups Concept
Note:
Since the CPRI protocol is based on the standards of 3G and LTE, the CPRI basic
frame length uses the UTRA FDD Chip period, 1/3.84 MHz, that means the resulting data
rate amounts 3.84 MHz.
