Technical Overviews
Technical Overview
Accelerate production of high volume quality phones at the lowest possible cost
Flexible
- The E1968A includes all essential connection types and signaling options necessary for a complete GSM/GPRS/ EGPRS/E-EDGE manufacturing test solution
- Some licensed feature options can also be used in R&D and reduce your R&D cycle fast
- Digital ORFS – up to 20x faster
- Dynamic power – fast automatic signaling and non-signaling method for Tx output power calibration
- Phase and amplitude versus time (PAvT) – measurement for calibration of polar modulated devices
- Fast device tune (FDT) – faster simultaneous mobile phone Rx and Tx calibration (based on typical test plan)
- Discontinuous timeslot TXP – supports simultaneous power measurement for up to 7 timeslots, reduces phone calibration time
Key features
- PAvT and IQ capture functionality
- Enhanced fast device calibration across level and frequency simultaneously
- E-EDGE2-A signaling and measurement
- VAMOS type I and type II solutions for mobile R&D and manufacturing
- Test mode BER reduces your BER measurement time in production without setting up a call connection; MS calculated BER separates the Rx from Tx test and reduces Rx test time through multi-phone test scenario
- Class 45 feature enables simultaneous Tx and Rx measurement of all bursts up to 6 uplink timeslots
- Real-time audio codec and DAI interface
- Free text-type SMS functionality and licensed full functionality SMS
- Single channel GPS source
- FM radio source allows easy FM radio phone calibration in production
- 2-box voice handover between GSM and W-CDMA
GSM/GPRS/EGPRS/E-EDGE Signaling and Base Station Emulation
The E1968A GSM/GPRS/EGPRS/E-EDGE mobile test application gives you the test solution designed especially for your GSM/GPRS/EGPRS test requirements of transceivers and wireless terminals by delivering speed and flexibility needed for high-volume, automated production-test environments.
Since this solution is based on the high-performance E5515C/E (8960) wireless communications test set, you get speed and concurrent measurement capabilities, providing immediate benefits that translate into a competitive advantage for mobile phone manufacturers. This significantly cuts test times, helping reduce the manufacturing cost per phone.
