QPSK EVM Measurement
SPAN X Scale
X Auto Scaling
Determines the scale per division and reference value for the X axis based on the current measurement
results.
Auto Scaling (X Scale, Magnitude Error Window)
When Auto Scaling is On and the Restart front-panel key is pressed, this function automatically displays
the scale per division and reference value results in the magnitude error window.
Auto Scaling (X Scale, Phase Error Window)
When Auto Scaling is On, upon pressing the Restart front-panel key, this function automatically displays
the scale per division and reference value results in the phase error window.

SPAN X Scale
Mode WCDMA, C2K, 1xEVDO
Notes When On, the Scale/Div, Ref Value, and Ref Position are reset to the default
values.
The mode must be W-CDMA, 1xEVDO or cdma2000 to use this function.
Use :INSTrument:SELectto set this mode.
Couplings Upon pressing the Restart front-panel key, the scale coupling function
automatically determines the scale per division and reference values based on
the measurement results if this parameter is set to On. When you set a value to
either Scale/Div or Ref Value manually, Scale Coupling automatically
changes to Off.
Preset ON
