Introductory Programs
The introductory programs in this section include:
– AFG Self-Test
– Resetting the AFG and clearing its status registers
– Querying the AFG power-on/reset settings
– Checking for Errors
– Generating a sine wave with a single command
AFG Self-Test The AFG self-test is executed with the command:
*TST?
The AFG parameters tested include:
– internal interrupt lines
– waveform select RAM
– segment sequence RAM
– waveform segment RAM
– DDS/NCO operation
– sine wave generation
– arbitrary waveform generation
– marker generation
– waveform cycle and arm counters
– sweep timer
– frequency-shift keying
– stop trigger
– DC analog parameters (amplitude, offset, attenuators, filters,
calibration DACs)
Upon completion of the test, one of the self-test codes listed in Table 1-2 is
returned.
