Test 2-2: DC Accuracy
Description
The purpose of this test is to verify that the AFG mee ts it s spe cifications for
DC 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. Set up the AFG to output a DC signal:
FUNC DC; Select DC waveform
:OUTP:LOAD INF; Infinite load
:VOLT MAX Set amplitude
Perform ste ps 3 - 5 for each amp litude listed in Ta ble 2-2:
3. Set up the AFG output filter as specified in Table 2-2. 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
4. Set the AFG output amplitude:
VOLT <amplitude> Set amplitude
where <amplitude> is the value specified in Table 2-2.
5. Trigger the DMM and record the r eading.
