If the image rejection is not known, R&S FS-K30 can still be used to produce accurate 
noise results. However, the gain of the DUT must be known and an additional filter is 
required.

In this test setup, a lowpass prevents noise from the noise source from being fed in at the 
image frequency. Depending on the position of the frequency bands, a highpass or bandpass 
may also be necessary for the RF frequency instead of the lowpass. The important point is 
that noise from the noise source is not converted by a further receive path of the mixer. The 
noise of the noise source at the receive frequency must not be reduced. The insertion loss 
must be considered, if applicable. 
With this test setup, the measurement on a mixer without sideband suppression corresponds to 
the measurement on a single-sideband mixer, and as setting the 

Image Rejection 

parameter 

in the Frequency Settings view to a large value (e.g. 999.99dB) will produce accurate results. 
If the characteristics of the filter are to be taken into account, the insertion loss of the filter at 
the RF frequency can be entered in the 

Loss Settings 

view. If the actual filter suppression 

at the image frequency is to be considered as well, do not enter 999 dB but the actual 
attenuation in the 

Image Rejection 

parameter. 

Measurements on a harmonics mixer 

For a harmonics mixer, the input signals are not only converted to the IF by the wanted 
harmonic, but also by the harmonic of the LO signal produced in the mixer. In many cases, 
the mixer even features a lower conversion loss in the case of unwanted harmonics. For 
measurements on this type of mixer a bandpass filter must be used to make sure that that 
there is only noise at the desired input frequency at the input of the DUT. This measurement 
is similar to measurements on a mixer with an average sideband suppression.
