IQ Output, Spurious Free Dynamic Range (SFDR)
Note:
Make sure that the measured spurious signal does not come from the analyzer. The following tests
can be performed for this purpose:
-
Switch off the signal from the DUT and repeat the measurement; if the signal remains, it may come from
the analyzer.
- Output the signal from the DUT with a slight frequency offset; if the signal remains, it may come from the
analyzer.
The number of necessary measurement depends on the number of installed RF- and baseband paths, see
following table:
Installed paths
1 x RF
1 x BB
2 x RF
2 x BB
2 x RF
1 x BB
1 x RF
2 x BB
I/Q output: spurious free dynamic range
Number of measurements 1 x 2 x 2 x 1 x
