R&S SMU200A Test Procedures
1007.9845.82 1.55
E-12
Output voltage
Test equipment AC/DC Voltmeter R&S URE 3 (table 1-1, pos. 19).
Test setup
Connect the voltmeter to the I/(and Q)-output of the DUT
.
Test method
A single sideband signal is generated using the Custom Digital
Modulation functionality by selecting only one carrier (DC-Signal), the
offset is set with the Frequency Offset function in the Baseband menu.
The test levels are set one after the other.
