AMPTD Y Scale
Accesses the AMPTD Y Scale menu that allows you to set the desired vertical scale and associated
settings. This menu is available when in “I/Q Error” view. It is not available when in the following
views: “I/Q Measured Polar Graph” or “Power, Timing and Phase”.
Ref Value
Sets the absolute power reference value ranging from –500.00 to 500.00 dBm with 0.01 dB resolution.
However, since Auto Scaling defaults to On, this value is automatically determined by the measurement
result. When you set a value manually, Auto Scaling automatically changes to Off.
I/Q Error View - EVM Window
Sets the absolute power reference value in the EVM window.
