Test 2-1: DC Zeros (cont’d)
Test Procedure
(cont’d)
3. Create a user-defined waveform made up of zeros:
LIST:SEGM:SEL ZEROS Select segment name
LIST:SEGM:DEF 8 # of segment points
LIST:SEGM:VOLT 0,0,0,0,0,0,0,0 Segment list
LIST:SSEQ:SEL DC_ZEROS Select sequence name
LIST:SSEQ:DEF 1 # of segments
LIST:SSEQ:SEQ ZEROS Sequence list
4. Set up the A FG to output the wa veform defined ab ove:
ROSC:SOUR CLK10; Select 10 MHz clock
:VOLT MAX; Set amplitude
:OUTP:LOAD INF; Infinite load
:FUNC USER Select user waveform
FUNC:USER DC_ZEROS Select sequence
INIT:IMM Initiate wave form
Perform ste ps 5 - 7 for each amp litude listed in Ta ble 2-1:
5. Set the AFG output filter as specified in Table 2-1. Use the
appropriate command(s) below:
OUTP:FILT OFF Disable filter
or
OUTP:FILT:FREQ 250KHZ Select 250 kHz filter
OUTP:FILT ON Enable filter
or
OUTP:FILT:FREQ 10MHZ Se lect 10 MHz filter
OUTP:FILT ON Enable filter
6. Set the AFG output amplitude:
VOLT <amplitude> Set amplitude
where <amplitude> is the value specified in Table 2-1.
7. Trigger the DMM and record the r eading in Table 2-11.
