70 -- HEWLETT PACKARD MULTI-FORMAT COMMUNICATIONS SIGNAL SIMULATOR MODEL 50 SYSTEM OR EQUAL SOL DTRS57-95-R-00028 DUE 081195 POC Donna J. Waldron, Contracting Officer FAX (617)494-2482. The Volpe National Transportation Systems Center intends to negotiate on a sole source basis with Hewlett Packard 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 results of the sources sought synopsis which was published in the CBD on 5/12/95 support our decesion that Hewlett Packard is the only known source that has demonstrated ability to provide the requisite equipment meeting 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 collection program, vary scenario parameters (such as peak power and carrier frequency) and then execute the data collection program again.
