Question # Question Government Response

If the desire is to remove the ATLAS dependency, then the assumption is the legacy

APS’s will be rewritten using the new software language/Hardware Abstraction

Layer (HAL). Is that a correct assumption?

The intent is to fully transition away from the ATLAS programming language. Legacy Application

Program Sets (APS) will require a complete rewrite into a modern software language. The use of a

Hardware Abstraction Layer (HAL) in the proposed architecture is a strategy for vendors to consider.

Is this effort focused only on the NxGenGPATS system, or does it also include APS development or rehost?

The scope of this effort encompasses the entire test system capability, including Application

Program Sets (APS) development or rehosting.

Does the USMC already have a modernized HAL that they would like to re-use or leverage on the NxGenGPATS?

The Government is in the process of developing a modernized Hardware Abstraction Layer (HAL).

However, vendors should not consider this Government-developed HAL a dependency for their proposed solutions.

What are the environmental requirements (MIL-STD-810, MIL-PRF-28800 class

1/2/3, etc.)?

The environmental requirements include compliance with MIL-PRF-28800 (Test Equipment for

Use with Electrical and Electronic Equipment) for Class 2 storage and Class 3 operating conditions.

The Marine Corps anticipates that the following standards will also apply:

MIL-HDBK-209: Sling Loading and Tie-Down Provisions

Can the Government provide a list of the Line Replaceable Units (LRUs) and

Electro-Optical (EO) systems that are currently tested by the legacy TETS and

VIPER/T?

Yes, the Government will provide a list of the currently supported Line Replaceable Units (LRUs) and Electro-Optical (EO) systems.

Will there be a requirement for testing Shop Replaceable Units (SRUs) (i.e. circuit boards) on NxGenGPATS?

Yes, the NxGenGPATS must be capable of testing Shop Replaceable Units (SRUs) to the circuit card and electronic module level.

Next Generation General Purpose Automatic Test System (NxGenGPATS) M67854-26-I-5416 Questions and Answers

There are no specifications provided with the RFI. Can a specification be provided to determine the instrumentation needed for NxGenGPATS?

Enclosures 1 and 2 are available by request. Non-Disclosure Agreement (NDA) will be provided and will include the necessary details to request specifications.

What is the frequency range of the RF source and measurement instrumentation required?

There shall be an RF stimulus capable of delivering an RF signal from 10 MHz to 40 GHz at a level of -90 dBm to +10 dBm with a level of accuracy of ± 2 dB.

9 Can the Government define the number of digital I/O channels required? The preferred number of channels for the Digital Test Subsystem is 192 bi-directional pins.

What are the environmental, EMI/EMC and safety requirements for the

NxGenGPATS?

The environmental requirements include compliance with MIL-PRF-28800 (Test Equipment for

Use with Electrical and Electronic Equipment) for Class 2 storage and Class 3 operating conditions, MIL-STD-461: Requirements for the Control of Electromagnetic Interference (EMI) and MIL-STD-882: Standard Practice for System Safety.

Does the Government desire to reuse the Hardware Abstraction Layer (HAL) in the

NxGenGPATS software architecture design?

The Government is in the process of developing a modernized Hardware Abstraction Layer (HAL).

However, vendors should not consider this Government-developed HAL a dependency for their proposed solutions.

The Power Distribution Unit (PDU) described in the RFI document requires the ability to accept three (3) different input sources. There was much discussion in the past that this requirement would be changed to only one single-phase AC requirement to reduce the size and complexity of the PDU. In fact, the previous RFI released in May 2023 required GPATS operation from only 120 VAC nominal input power. Are the multiple power inputs a firm requirement?

The multi-source input is not a firm requirement for the core system. The core system should be designed to operate from 120 VAC nominal input power. However, the Government is open to solutions that include optional, modular components to accommodate other power sources.

The RFI mentions a requirement to provide power to Electro-Optical (EO) components. Does the Government plan to reuse the legacy VIPER/T VEO-2 collimator?

While the long-term plan includes replacing the collimator, vendors should propose solutions that provide the option to reuse the legacy collimator. This allows for flexibility considering the current limitations of the defense industrial base.

If the Government intends to reuse the legacy VIPER/T VEO-2 collimators with

NxGenGPATS, are there any plans to replace these collimators, which are now over

20 years old and difficult to support?

Yes, the Government plans to replace the legacy collimator in the future. However, for this effort, vendors must provide the option to reuse the existing VEO-2 collimator.

Can the +15 VDC and +28 VDC power required for the EO components be powered by two of the programmable (UUT) DC power supplies or do they have to be separate dedicated supplies?

The required EO power can be supplied by a single power supply, provided it is capable of handling the specified multiple outputs.

Is there a requirement to reuse the legacy Interface Test Adapters (ITAs) or TPS cables currently used on TETS and VIPER/T?

The Government's objective is to reuse legacy Interface Test Adapters (ITAs) and Test Program Set

(TPS) cables where it is feasible and practical to do so.
