The 8922P Dual-band Test Set is a combination of the 8922M GSM MS Test Set and the 83220E DCS/PCS Test Set and new firmware to form a complete dual-band (GSM 900/DSC 1800) test solution. All the original 8922 features are retained but now, with dual-band untra-cell handover capability, the latest GSM mobiles can be tested seamlessly, at all frequencies, through a single RF connector.
