Test 2-4: AC AccuracyDescription
The purpose of this test is to verify that the AFG mee ts it s spe cifications for
AC accuracy at 1 kHz.
Equipment Setup
•Connect equipment as shown in Figure 2-5
•Set DMM to ACV, autorange
Test Procedure
1. Reset the AFG:
*RST;*CLS Reset AFG and clear
status registers
2. Set up the A FG to output a 1 kH z sinewave:
FREQ 1E3; Set freq to 1 kHz
:VOLT MAX; Set to max amplitude
:OUTP:LOAD INF Infinite load
CAL:STAT:AC OFF AC corrections off
INIT:IMM Initiate wave form
Perform steps 3 - 5 for each amplitude and filter lis te d in Table 2- 4:
3. Set up AFG output filter as s pecified in Table 2-4. 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
