3 IQ Analyzer (Basic) Mode
3.2 IQ Waveform Measurement
When B2X/B5X/B1G/B1500M/B2G/B4G paths are available, in Auto mode, the
selections may be disabled if the center frequency of the measurement is not in
range of the minimum/maximum center frequency requirement for these IF Paths.
Depending on the specific hardware, the minimum/maximum center frequency
varies for these IF Paths. In Auto mode, these IF Paths become enabled when the
center frequency of the measurement falls within the valid frequency range
specified for that IF Path. In Auto mode, if the center frequency is not in range, the
application switches into the widest IF Path that can satisfy the center frequency. In
Manual mode, the center frequency is clipped to minimum/maximum value that
specific IF Path allows. A warning message alerts you of the settings conflict.

VMA Mode Digital Demod measurement, replace the <meas> node with that for the active
measurement; in this case DDEMod
