66 -- INSTANTANEOUS FREQUENCY MEASURING DEVICE AND A 3 YEAR WARRANTY FOR THE MEASURING DEVICE SOL RU7P5403 DUE 062797 POC (RDPC) Vickie Beaver, Contract Specialist, AMSMI-AC-CRBB, 205-876- 3139, Andy Eiermann, Contracting Officer, 205-876-8278, Synopsis Number R150-97. One each Instantaneous frequency Measurement Device (IFM) and a 3 year Warranty for the IFM. The IFM will be used to tune digitally controlled agile oscillators during Sentinel tests. To accomplish this task, the IFM shall be capable of continuously generating a digital word representing the center frequency of its currently received RF signal. This digital word shall contain a minimum of 12 bits and shall be output over an RS-232 or RS-422 interface operating at at least 38400 baud. The IFM shall process signals over an input frequency range of 8.0 to 12.0 Ghz and pulse widths ranging from 500 nanosec to CW. It shall report the center frequency of a received RF signal with an accuracy of +- 1.5 MHZ RMS. The IFM shall correctly process signals with power levels ranging from -40.0 to +5.0 dBM. The IFM shall have a maximum probability of false alarm (Pfa) of 5 per second where a false alarm is defined as the generation of the digital output word in the absence of a valid signal. Given this Pfa, the IFM shall achieve a mimimum probability of detection of 0.99 for a signal with a 6 dB signal to noise ratio (SNR) where a detection is defined as the generation of a correct digital output word in the presence of a valid signal. The IFM shall process and generate a digital output word within no more than 500 nanosec of beginning to receive a valid signal. Once a valid signal terminates, the IFM shall be ready to process a new valid signal within no more than 250 nanosec. The IFM shall have an RF input VSWR not exceeding 2.0:1 across the full input frequency range defined above. The IFM shall be delivered with a user's manual. At a minimum, this manual shall cover operation of the IFM, destructive signal levels, and interfacting to the IFM. The tests involving the IFM will be open loop outdoor tests. In light of this the IFM shall meet the following environmental specifications. The IFM shall meet all operating specifications defined above over a temperature range of +32 to +100 degrees F while sitting in direct sunlight. The IFM shall meet all operating specifications defined above for non-precipitating humidity levels ranging from 0 to 99 percent. Additionally due to the schedule driven nature of test programs, the IFM shall have a 3 year warranty. This warranty shall start on the date of acceptance of the IFM by the Government. The warranty shall cover all parts, labor, or return shipping to the Government. The IFM and the warranty shall be priced separately. All responsible sources may submit a bid, proposal, or quotation which will be considered by this agency. (0160)
