Making Mixer Measurements (Option 089 Only)
Measurement Considerations
Figure 2-5 Example of Conversion Loss versus Output Frequency with Correct
IF Signal Path Filtering and Attenuation at All Mixer Ports
How RF and IF Are Defined
When you choose between and in the frequency offset menus, the
analyzer determines which direction the internal source must sweep in order to achieve
the requested IF frequency. For example, to measure the lower sideband of a mixer, where
the RF signal is below the LO ( ), the internal source must sweep backwards. See
the examples in Figure 2-6.
