Description
The purpose of this test is to verify that the AFG meets its specifications for
DC offset accuracy.
Equipment Setup
• Connect equipment as shown in Figure 2-5
• Set DMM to DCV, autorange
Test Procedure
1. Reset the AFG:
*RST;*CLS Reset AFG and clear
status registers
2.
Delete all sequences and segments from memory:
LIST:SSEQ:DEL:ALL Delete all sequences
LIST:SEGM:DEL:ALL Delete all segments
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 AFG to output the waveform defined above:
ROSC:SOUR CLK10; Select 10 MHz clock
:OUTP:LOAD INF; Infinite load
:VOLT MAX; Set amplitude
:FUNC USER Select user waveform
FUNC:USER DC_ZEROS Select sequence
INIT:IMM Initiate waveform
