User-definable zones on frequency sub-bands enable visual identification of uplink and
downlink frequencies for compliance verification with a single measurement window.
You can use the Zoom function to have a closer look at the user-definable zoom zones in
different windows up to three zones. All the three zoom zones are turned off by default. It is
available for Reflection, 1 Port Cable Loss, 1 Port Phase, 2 Port Transmission, and 2 Port
