TEST:DISPlay?
TEST:DISPlay?
performs the test of the mainframe’s front panel function: display
window, monitoring LEDs, and beeper. There is no failure result for this test. The
display cycles through all pixels and all colors. The “Temp” / ”Fan” / ”Power
Supply” LEDs change states, and the beeper performs a Bach song (if
SYST:BEEP:STAT is enabled). The command returns an integer (always returns 0).
