Amplitude, Offset Accuracy and Rise Time Tests (for option 02)
These procedures check the accuracy of the AWG710 Arbitrary Waveform
Generator option 02 outputs; amplitude and offset.
Equipment
required
A 50ĂW BNCĂcoaxial cable, a 50ĂWĂprecision terminator, an
SMA(Ma)ĆBNC(Fe)Ăadapter, BNC (female)ĆtoĆdual banana adapter, and
a digital multimeter (DMM).
Prerequisites The AWG710 option 02 Arbitrary Waveform Generator must meet the
prerequisites listed on page 4-8.
Do the following steps to install the test hookup and set the test equipment
controls:
1. Use a 50 W BNC coaxial cable, an SMA(Ma)-BNC(Fe) adapter, a 50 W
precision terminator, and a BNC-to-dual banana adapter to connect the
AWG710 Arbitrary Waveform Generator CH1 output to the DMM input
connector (see Figure 4–12).
