AMPTD Y Scale
AMPTD Y Scale
Accesses the AMPTD Y Scale menu that allows you to set the desired vertical scale and associated
settings for the current measurement.
Ref Value
Enables you to set the absolute power reference value. However, since the Auto Scaling is defaulted to
On, this value is automatically determined by the measurement result. When you set a value manually,
Auto Scaling automatically changes to Off.
Ref Value (Magnitude Error Window)
Sets the absolute power reference value in the magnitude error window.
