Comment / Question Technical Answer/Remarks

1 Can pictures of the current Test Setup/Test Station be provided, along with any external control panels that control the receivers during testing? Pictures are attached.

2 Can pictures be provided of both the PAR & ASR receivers, along with their respective dimensions?

Pictures are attached.

3 Currently are these tests performed in the Radar shelter, or in a Lab setting? The tests are performed in the Radar Shelter

4 Are the receivers tested stand-alone, or do they require the rest of the system to be tested?

They currently require the rest of the system for testing.

5 Do actual Acceptance Test Procedures (ATP’s) exist to test the receivers? If so, can they be made available?

The Testing Requirements provided (TO's -22, -29,-22CL) are used as the Acceptance Test Procedure for the receivers.

6 Are there data sheets that the test technicians utilize for testing? If so, can they be made available? There are no test data sheets

7 The Echo Box described in the requirements seems like an older piece of equipment that may not be available; will that be supplied by Tobyhanna?

Tobyhanna will not supply an Echo Box. The testing must be replicated with modern equipment.

In the PAR & ASR requirements documents, references are made to “Steps 2.A, 2.C, 2.O“ etc., and those steps don’t exist in the documents. Is there another document with that information that will be provided?

The steps being referenced refer to previous steps in the same procedure.

In the PAR & ASR Theory of Operation documents, references are made to “Para 6.10.1” and it doesn’t exist in either document. Will Para 6.10.1’s information be provided?

Para 6.10.1 REMOTE Mode Maintenance Setup. This setup configures the PAR radar system so the ON LINE channel is operated and controlled from the operations trailer. The other channel will be in the MANT mode and controlled from the radar trailer.

a. On PAR local control-indicator, press SYSTEM CHAN A MAINT - CHAN B MAINT switch to case CHAN A MAINT indicator to flash.

b. On PAR remote control-indicator, press SYSTEM CHAN A MAINT switch to cause CHAN A MAINT indicator to light.

c. On PAR local control-indicator, verify that CHAN A MAINT indicator is lit and not flashing.

10 Are the PAR & ASR receiver control panels on the receivers or are they separate panels?

Some controls exist on the receivers, but there is also a separate control panel.

11 If the receivers are tested in a lab setting, will any special fixtures be required to house the UUT’s on the test station? No special fixture is required.

The Scope Graphs shown in the Requirements and Theory of Operation documents for each receiver have no limits associated with them. How will these be automated or verified with the software if no limits are specified?

The graphs should be used to create test limits, but these limits should be adjustable by the user.

Comments and Questions for Solicitation W25G1V-17-R-0019 AN/MPN-14K Test Station

13 Some tests require an additional person in an ‘Ops Van’. How does the ‘Ops Van’ interface/communicate with the current test setup? Can this test be developed and verified at our facility?

Cabling connects the Radar Van to the Ops Van, and there is a separate control panel located in the Ops Van. For the purposes of this test station, there would just have to be some way to connect to the appropriate receiver ports and show that it is possible to control the received signals

Both receiver tests seem to be mostly manual alignment procedures with many operator visual verifications. What are Tobyhanna’s expectations for automating these types of tests?

The graphs should be used to create test limits, but these limits should be adjustable by the user. User intervention may be required on certain steps.

15 In regards to data delivery, I see a list of documents to be delivered with the test station. I would like to clarify that there is no TO requirements in this solicitation. There is no requirement for any data in TO format. Contractor format is acceptable.
