Anritsu FAQs
In the MT8820A/MT8815A, how do I change the measurement system from WCDMA to GSM?
Push the [STD] Hard key. This displays the loaded measurement software. To change to GSM, push the soft key for the measurment system desired, in this case GSM. If GSM is not seen, you will need to verify that the system is available and loaded. Please consult the operation manual for more information.
