Current Formula
Apart from the current Frequency Conversion Formula, the analyzer firmware main-
tains a list of named, user-defined formulas.
●
"Add Formula to List..." adds the current frequency conversion formula to this list.
●
"Remove Selected Formula" removes the selected user-defined formula from this
list.
●
"Change Formula Name..." allows you to change the name of the currently
selected user-defined formula.
Note:
●
User-defined formulas are persisted in the recall set. A preset deletes all user-
defined formulas.
●
User-defined formulas are updated automatically: if a user defined formula is
selected and the "Frequency Conversion Formula" on page 618 is modified, then
the formula itself is modified. As a consequence, all "Freq. Conversion" definitions
using this formula are modified as well.
●
If a user-defined frequency conversion formula is removed from the list, all "Freq.
Conversion" definitions using this formula are replaced by the "unlinked" formula.
Frequency Conversion Formula
The conversion formula has been modeled according to the needs of a typical fre-
quency-converting measurement where mixer products, intermodulation products, or
harmonics occur.
●
For mixer measurements, select a "Base Ratio" of 1, a "Frequency Offset" equal to
the LO frequency, and an "Offset Ratio" of ±1. If the RF signal is at the channel
base frequency, the port frequency is at the frequency of the upper (lower) side-
band.
●
To measure n-th order intermodulation products, select integer "Base Ratio" and
"Offset Ratio" with |"Base Ratio"| + |"Offset Ratio"| = n .
●
To measure the n-th harmonic of the channel base frequency, select a "Frequency
Offset" of 0 and an integer "Base Ratio" = n.
