for custom signal analysis by enabling
users to input customized measurement
locations for the Frequency Response
and Noise measurement parameters.
For frequency response measurements,
users can select either timing location
input or frequency input to make response
measurements anywhere within the
supported video bandwidth utilizing a
standard sweep signal. Input locations
can be further toggled within YPbPr
signals to accommodate either 4:2:2 or
4:4:4 video. This enables detailed analysis
of roll-off, frequency distortion, identification
of spurs and aliasing anywhere across the
useful frequency spectrum.
Flexible Noise Measurement – Options
SD and HD offer the capability to make
both weighted and un-weighted noise
measurements. Default selections for
