Occupied Bandwidth Measurement
AMPTD Y Scale (Amplitude/Y Scale)
AMPTD Y Scale (Amplitude/Y Scale)

Activates the Reference Value function and displays the Amplitude menu keys. These functions control

how data on the vertical (Y) axis is displayed and control instrument settings that affect the vertical axis

See “AMPTD Y Scale” on page 849 for more information.

Ref Value

Sets 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.
