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

Execute the AFG self-test:

*TST? Self-test command

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".
