70 -- HP MULTI-FORMAT COMMUNICATIONS SIGNAL SIMULATOR MODEL 50 SYSTEM OR EQUAL SOL DTRS57-95-R-00028 DUE 061995 POC Donna Waldron, Contracting Officer FAX (617) 494-3649. The Volpe National Transportation Systems Center has a need for a Hewlett Packard Multi-Format Communications Signal Simulator Model 50 System or equal to expand the Center's capability to simulate sources of GPS interference. The signal source shall meet the following requirements: 1. Generate multiple channels of interference from 800 MHZ to 2 GHz. 2. Generate signals as high as 0 dBm and down to -70 dBm. 3. Generate signals with various modulation patterns, including frequency, amplitude, pulsed, BPSK, PI/4DQPSK, MSK and FSK. 4. Generate user defined waveforms. 5. Generate signals with a bandwidth up to 50 MHZ. 6. Generate from 1 to 100 channels within a 25 MHZ bandwidth with variable channel spacing and with combinations of channels on, off, or modulated. 7. Generate signals with a bit rate from 1 kHz to 10 MHz with a signal length of 4 msec repeating. 8. This equipment must have a manual and a computer (IEEE-488) interface. 9. This equipment must allow for automated tests similar to those now being performed. PC based software must be provided which allows the user to select and execute an interference scenario and then without manual intervention execute another DOS data colection program, vary scenario parameters (such as peak power and carrier frequency) and then execute the data collection program again. Material to be delivered to the Volpe Center within 14 weeks of contract award. In the absence of responses from firms who can demonstrate their capability to perfrom this requirement, the Volpe Center intends to negotiate with Hewlett Packard Co. on a non competitive basis for the item described above. The authority for this action is 41 U.S.C. 253 (c)(1). All responsible sources may respond to the synopsis and all responses will be fully considered by the agency. Interested firms are asked to submit 2 copies of descriptive literature on the above item to the contracting Officer within 15 days from the published date of this notice in the Commerce Business Daily. No contract will be made on the basis of offers/proposals received in response to this synopsis since this notice is not a request for offers/proposals See numbered Note 22. Responses must reference Procurement Request No. 53-127.
