(cont’d)
4. Set up the A FG to output a 1 MHz s inewave with an exte rnal gate
source:
TRIG:GATE:SOUR EXT; External gate source
:TRIG:GATE:STAT ON; Enable gate
:FREQ 1E6; Set freq to 1 MHz
:VOLT 4VPP Set AFG amplitude
INIT:IMM Initiate
5. Send the following command to the Command Mo dule to se t the
level at the "Trig Out" port to 5 V. Verify that the scope shows a 1
MHz sinewave.
OUTP:EXT:LEV 0
6. Send the following command to the Command Mo dule to se t the
level at the "Trig Out" port to 0 V. Verify that the scope shows a DC
signal.
OUTP:EXT:LEV 1
