Test 2-3: DC Offset (cont’d)
Test Procedure
(cont’d)
Perform steps 5 - 7 for each offset listed in Table 2-3:
5. If necessary, change the AFG output amplitude:
VOLT:OFFS 0; Set offset to 0
:VOLT <amplitude> Set amplitude
where <amplitude> is the value specified in Table 2-3.
6. Set AFG offset voltage:
VOLT:OFFS <offset> Set offset
where <offset> is the value specified in Table 2-3.
7. Trigger the DMM and record the reading.
