12 LitePoint Confidential 12 Why LitePoint -- Formular LitePoint

13 LitePoint Confidential #1 Cellular multi-DUT Parallel Tester – Y2011 13 First Parallel Testing Solution

14 LitePoint Confidential Utilization Maximizing Technology (UMT) Smart Multi-DUT Testing Architecture -Optimized resource usage – best utilization -Optimized hardware and software integration – highest throughput Key Elements -Dynamic Signal Control (DSC) -Intelligent Signal Processing -Smart Data Export Dynamic Signal Control Data Processing Data Export Data Capture Data Processing DUTs Built in Calibration Point to Point Connections Dynamic Reference Level Control Per DUT Signal Detection Parallel Processing Pipelined Data Transfer Smart Data Export Synchronized Captures

15 LitePoint Confidential PWR Multi-Channel Measurement Architecture  Traditional Test Architecture supports only one measurement at a time setup measure fetch  IQxstream Architecture Multiple instrument channels support multiple, simultaneous measurements EVM setup measure fetch OBW setup measure fetch ACLR setup measure fetch Capture setup … PWR EVM OBW ACLR Data 15

16 LitePoint Confidential Better Test Coverage, Less Test Time  W-CDMA TX test example ILPCACLREVMI/Q Imb. Time ACLREVMI/Q Imb. Power Level 1 Power Level 2 ACLR EVM I/Q Imbalance ACLR EVM I/Q Imbalance ACLR EVM I/Q Imbalance Power Level (dBm) Slot … ILPC ACLR EVM I/Q Imb. Time ACLR EVM I/Q Imb. 16

17 LitePoint Confidential Sequence-Based Test Programming  Traditional Methods require sending instructions to (“setup”) the DUT at the beginning of each measurement in a series of tests DUT + TE setup meas #1 TE setup meas #3 meas #2 meas #N Test Time DUT setup Load the test sequence Traditional Non-Signaling Sequence Based Non-Signaling meas #1 meas #2 meas #3 Execute test sequence DUT setup meas #1 meas #2 meas #3  IQxstream Method:  pre-program a “sequence” (several SCPI commands) only once  IQxstream and then execute many times with one command 17

19 LitePoint Confidential 19 Throughput -- more than RF Test Speed

20 LitePoint Confidential Offering Flexibility in Manufacturing (And a smooth transition to automated, multi-DUT testing) 20 Manual Loading Automated Loading / Panel Test 1-DUT Sequential (1x1 ping-pong) Multi-DUT Synchronous (4 devices in 1 chamber) Manual Loading Multi-DUT Asynchronous (4 devices in semi-parallel) 2013 and before NowWhen you’re ready

21 LitePoint Confidential Why Does APT Work? (Example: TX Calibration) 1-DUT DUT control, settling time, NV write 30% Utilized 0% 100% 70% Idle 2-DUT 60% Utilized 0% 40% Idle 3-DUT 90% Utilized 0% 10% 4-DUT Nearly 100% Utilized 0% 100%

22 LitePoint Confidential APT Integration Requirements LitePoint APT easily PnP in any ATE SW with minimal changes required Keys: 1.“Turn off” tester when DUT fails 2.“Turn off” tester when DUT passes 3.“Turn off” tester when DUT finishes (before NVs written) Upper S/W layer does not need to need to be: 1.“Multi-DUT aware” – just starts multiple 1-DUT programs 2.Aware of any other DUT program – all handled through in-box tokens 3.Thread safe Zero Risk to any ATE SW

23 LitePoint Confidential Maximum performance using APT Asynchronous Parallel Test drivers benefits Application side driver is written as a single threaded driver No shared memory, or application side synchronization required Works with 1 – …n DUT’s. Plugs into existing API’s from any test framework without any architecture changes required. Maximum performance achieved with simple API call to turn off the Generator when testing is completed. (Pass, Fail, Abort, Prior to NVM) Works for both calibration and verification Common core driver can operate in multiple modes of operation Exclusive Resource Maximum distribution Shared Resource Cadence Enforced Mode ( CEM-1, CEM-2, CEM-4) CEM-1 = 1x1x1 CEM-2 = 1x2x2 CEM-4 = 1x4

24 LitePoint Confidential “Asynchronous” Does Not Mean “Chaotic” New token priority system helps manage asynchronous test processes Key benefits: -Ensures maximum operator efficiency in the factory – minimal idle time -Asynchronous processes do not need to be aware of other processes DUT #1 DUT #2 DUT #3 DUT #4 DUT #1 DUT #2 DUT #3 DUT #4 Time Unmanaged Asynchronous ProcessesMaximum Asynchronous Distribution

25 LitePoint Confidential Synchronizing Asynchronous Processes How do we go from: DUT #1 DUT #2 DUT #3 DUT #4 Here DUT #1 DUT #2 DUT #3 DUT #4 …to here? AsynchronousSynchronous

26 LitePoint Confidential Combining APT & SPT By leveraging token prioritization, the test program can automatically align multiple asynchronous processes Key benefits: -Same operational benefit of APT, and eliminates wait time between Cal and Ver -Again, asynchronous processes do not need to be aware of other processes DUT #1 DUT #2 DUT #3 DUT #4 DUT #1 DUT #2 DUT #3 DUT #4 Time Asynchronous ProcessesSynchronous Processes
