Sample SCPI Command Scripts
This section has two scenarios in which SCPI commands are used to setup the ESG to transmit a Broadcast
Channel (BCH).
Example 1, Setting Up a Non-Combined Broadcast Channel
This example will setup the ESG to generate a Non-Combined Broadcast Channel at 935.2 MHz with a
power level of –10 dBm. A public land mobile network (PLMN) value of 2 will be chosen and a base station
colour code (BCC) value of 3 will be set. The trigger will be setup in “trigger and run” mode which means
that the ESG will start generating a BCH on receipt of the first trigger and any further triggers will be
ignored. The trigger will be setup to use the external pattern trigger 1.
Reset the ESG to its power on state.
