Flightline Test In Your Hand
Chassis Controllers and Bus Expanders
All Chassis and Controllers Products
The first six months of 2016 have been busy and exciting, and the pace continues as we move into the second half of the year. We are incorporating exciting technologies into our new product releases as we continue to focus on innovative solutions that make test easy for our customers.This issue of Test Connections highlights our test solutions for Maverick and Hellfire Missiles with our flightline and I-Level equipment, Serial Peripheral Interface (SPI) Bus emulation with our flagship digital product - GX5296, and a production test solution for miniaturized electronics using ATEasy.We look forward to seeing many of you at the Farnborough Air Show and other aerospace and defense shows in the coming weeks.Steve Sargeant, CEO
We hope you enjoy this month's issue of Test Connections which includes new product updates and news events.

O-Level TestFor O-Level test, the MTS-3060 SmartCan™, a high-performance portable handheld test set, offers previously unavailable trouble-shooting capabilities, such as full-functionality testing of the 1760 bus to the flightline, along with select smart weapon emulation. With expanded capabilities that include full-functional testing of the AIM-120 AMRAAM, the MTS-3060 is the only handheld flightline test set capable of supporting MIL-STD 1760 functional testing beyond stray voltage and continuity of circuit test. The ability to test the AMRAAM’s MIL-STD 1760 connectivity to the aircraft enhances mission effectiveness and aircrew confidence, especially in situations where live-firing is required. This new AMRAAM test capability has been deployed internationally on Block 15 and 50 F-16’s and has been demonstrated domestically on the F-15. The MTS-3060 SmartCan™ has already secured foreign military sales (FMS) on several aircraft platforms.
I-Level TestFor I-Level test, the MTS-206 Series Field Test Set has also evolved, expanding its support beyond the basic AGM-65 Maverick Missile family to include the new Laser Maverick and the widely deployed AGM-114 Hellfire Missile system.

With the system timing configured, each DIO's channel can be assigned to one of four Phases (0-3) and one of four Windows (0-3). The Phases determine when a Drive signal will be asserted and or returned (denied) during the timing cycle and the Window setting determines when the data Sensing window opens and closes. The GX5296 supports up to 64 Timing Set groups, which are used to define the phase and window timing values for each sequence step. Referring to the timing diagram in Figure 5, the SCLK signal transitions from a low to a high at 50% of the cycle, and to achieve this clock period, Phase Assert0 must be set to 0ns and Phase Return0 to 20ns. Since data formatting for this channel is set to Return to One, this will generate the desired clock frequency as long as the vectors for this channel are set to output a logic low. The SS, MISO and MOSI channels are set to No Return formatting. These channels are valid at the beginning of the period and remain constant during the timing cycle so Phase Assert1 is set to 0ns. Phase Return1 is not used but needs to be set to some value greater than the Phase 1 Assert value, say 20ns.
• Phase Assert0 to 0.00• Phase Return0 to 20.00• Window Open0 to 30.00• Window Close0 to 40.00• Phase Assert1 to 0.00• Phase Return1 to 20.00• Window Open1 to 20.00• Window Close1 to 40.00
