Converted Frequency
In the Source and Receiver sections of the Port Configuration table, it is possible to convert the source
and receiver frequency ranges (for frequency sweeps) or CW frequencies (for power, time and CW
Mode sweeps) in order to perform measurements on frequency-converting DUTs. The source
frequency is port-specific whereas the receiver frequency must be the same at all ports.
Source frequencies are coupled if several sources share a common synthesizer. Refer to the
synthesizer mapping information in the Hardware Info overview to find out which of the ports are
coupled.
The port frequencies are calculated as a multiple of the stimulus frequency f
b
plus an offset. The
coefficients of the linear transformation between f
b
and the port frequencies are entered in dialogs of the
following type:
Relation between channel frequency and port frequencies
The stimulus frequency f
b
is defined by the following sweep settings:
•
For a frequency sweep or segmented frequency sweep, the channel frequency is equal to the
stimulus range.
•
For a power, time or CW Mode sweep, the channel frequency is equal to the fixed CW
Frequency .
This linear frequency conversion formula has been modeled according to the needs of a typical
frequency-converting measurement where mixer products and harmonics occur (see also the special
Mixer Mode and Harmonic Distortion measurements). The port frequencies f (source frequency f
s
or
receiver frequency for the reference channel and the measurement channel fra/frb) are related to the
stimulus frequency as follows:
k and m must be integer numbers, l and n nonzero positive integers. c must a multiple of 1 Hz.
Moreover the total port frequency is rounded to an integer Hz-value.
