Chapter 6 Application ProgramsUsing the Low-Level CommandsUsing the Low-Level CommandsThis program teaches the following concepts:œ How to use the low-level commands to set up an AM waveform.œ How to use the *SAV command to store the instrument configurationin memory.BASIC / GPIB (Program 2)10 !20 ! This program uses low-level SCPI commands to configure30 ! the function generator to output an AM waveform.40 ! This program also shows how to use "state storage" to50 ! store the instrument configuration in memory.60 !70 CLEAR 7 ! Clear interface - send "device clear"80 ASSIGN @Fgen TO 710 !
