For more information see "External Mixers and Large Bandwidth Extension Options"
on page 413.
"2 Port" LO and IF data use the same port
"3 Port" LO and IF data use separate ports
Remote command:
[SENSe:]MIXer<x>:PORTs

Mixer Settings (Harmonics Configuration)
The harmonics configuration determines the frequency range for user-defined bands
(see
"Band" on page 421).
Range 1/Range 2 ← Mixer Settings (Harmonics Configuration)
Enables the use of one or two frequency ranges, where the second range is based on
another harmonic frequency of the mixer to cover the band's frequency range.
For each range, you can define which harmonic to use and how the conversion loss is
handled.
Remote command:
[SENSe:]MIXer<x>:HARMonic:HIGH:STATe
on page 1079
Harmonic Type ← Mixer Settings (Harmonics Configuration)
Defines if only even, only odd, or even and odd harmonics can be used for conversion.
Depending on this selection, the order of harmonic to be used for conversion changes
(see
"Harmonic Order" on page 422). Which harmonics are supported depends on the
mixer type.
Remote command:
[SENSe:]MIXer<x>:HARMonic:TYPE
on page 1080
Harmonic Order ← Mixer Settings (Harmonics Configuration)
Defines which order of the harmonic of the LO frequencies is used to cover the fre-
quency range.
By default, the lowest order of the specified harmonic type is selected that allows con-
version of input signals in the whole band. If due to the LO frequency the conversion is
not possible using one harmonic, the band is split.
For the "USER" band, you define the order of harmonic yourself. The order of har-
monic can be between 2 and 128, the lowest usable frequency being 16.88
GHz.
Remote command:
[SENSe:]MIXer<x>:HARMonic[:LOW]
on page 1080
[SENSe:]MIXer<x>:HARMonic:HIGH[:VALue]
on page 1080
Conversion Loss ← Mixer Settings (Harmonics Configuration)
Defines how the conversion loss is handled. The following methods are available:
"Average" Defines the average conversion loss for the entire frequency range in
dB.
