INITiate commands should be sent only when the test set has finished performing any operations, such as
handovers, that require settling. For example, the following code performs a handover to a new traffic channel
using the :SEQ (sequential) appendage, then initiates a TX power measurement.
OUTPUT 714;”CALL:TCH:SEQ 65”
!Hands over traffic channel to channel 65, waits for process to complete before accepting next
command
OUTPUT 714;”INITiate:TXPower”
!Initiates TX power measurement
