H Push the AWG2005 MANUAL TRIGGER button, and check that
the displayed step is Step 3.
H Note the DMM reading as "C" for this value.
H Push the AWG2005 MANUAL TRIGGER button, and check that
the displayed step is Step 4.
H Record the DMM reading as "D" for this value.
H Do the following calculation.
C - D
H Check that the calculated value is in the range from 9.850 V to
10.15 V.
4. Move the connection for the coaxial cable from the AWG2005 CH1
output to AWG2005 CH2 output connector.
5. Repeat procedure 3.
6. If Option 02 is installed (adds CH3 and CH4 output channels): Repeat
above procedure for CH3 and CH4 outputs.
7. End procedure: Retain the test hookup and control settings.
This procedure checks the accuracy of the AWG2005 offset.
Electrical Characteristic Checked:
page 1 12.
Equipment Required:
dual banana adapter, and a digital multimeter (DMM).
Prerequisites:
The AWG2005 meets the prerequisites listed on page 4 7.
Procedure:
1. Install test hookup and set controls:
a. Hook up DMM: Connect the AWG2005 CH1 output through a 50 Ω
coaxial cable, a 50 Ω termination, and a dual banana connector to
the DMM INPUT connector (see Figure 4 14).
