Test 2-8: Duty CycleDescription
The purpose of this test is to verify that the AFG mee ts it s spe cifications for
square wave duty cycle. Duty cycle i s determined by measuring positive
pulse width.
Equipment Setup
•Connect equipment as shown in Figure 2-9
•Set Counter to: Pulse Width, DC coupling, 50Ω input impe da nc e
Test Procedure
1. Reset the AFG:
*RST;*CLS Reset AFG and clear
status registers
2. Set the AFG to output a square wave:
FUNC SQU; Select squarewave
:VOLT MAX Set to max amplitude
Perform steps 3 - 7 for each frequency listed in Table 2- 8:
3. Abort the waveform if it has been previously initiated:
ABORT
