3 WLAN Mode
3.12 IQ Waveform Measurement
Lets you alternate between mixing modes for the Local Oscillator (LO). The default
setting is NORMal LO mixing mode, which is determined by the instrument
configuration to be either “high side” or “low side”. The query returns “High” or
“Low” to determine whether the mixing is “high side” or “low side”. If Mixing Mode is
toggled between NORMal and ALTernate, then Mixing Mode State also toggles
between “High” and “Low”.
Remote Command
[:SENSe]:SPECtrum:LO:MIXMode:SIDE?
[:SENSe]:WAVeform:LO:MIXMode:SIDE?
Example
:SPEC:LO:MIXM:SIDE?
:WAV:LO:MIXM:SIDE?
Dependencies Not available in N9000B
Couplings When Mixing Mode is toggled between NORMal and ALTernate, Mixing Mode State also toggles
between High and Low
Range High | Low

:WAV:IF:FREQ?
Couplings A change in Span, Digital IF BW or IF Path parameters can result in a change of the IF Frequency value
3.12.8.4 Global
The controls in this menu apply to all Modes in the instrument.
Some controls (for example, "Global Center Freq" on page 1850) allow you to switch
certain Meas Global parameters to a Mode Global state. These switches apply to all
Modes that support global settings. For example, no matter what Mode you are in
when you set Global Center Freq to ON, it applies to all Modes that support Global
settings.
Other controls (for example, Extend Low Band) are actually set in this menu, but
apply to all Modes.
Global Center Freq
The software maintains a Mode Global value called Global Center Freq.
