Functional Verification: Self-Test
Description
The AFG self-test performs the following internal checks:
• 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)
Test Procedure
1. Remove any connections to the AFG front panel.
2. Reset the AFG:
*RST;*CLS Reset AFG and clear
status registers
3.
Execute the AFG self-test:
*TST? Self-test command
4.
Read the result. A "0" indicates that the test passed. A "1" indicates a
failure. Read the error queue using the SYST:ERR? command until
the error message is "No error".
