2. SUPPORTING DOCUMENTATION FOR SOLE SOURCE/BRAND NAME

BASED ON CONTRACTOR’S UNIQUE QUALIFICATIONS OR NATURE OF

THE ACQUISITION

The test site team has been utilizing Rohde and Schwarz items for electronic testing and the current equipment is approaching obsolescence. They are proven to be accurate and reliable, and are much more sensitive than lower cost options which is critical for testing electronic components for the new BRR-6C buoy, which is to installed on the CLB submarines. The test site team is familiar with Rohde and Schwarz equipment, and they would need to learn the configuration of new equipment which would be unacceptable in order to meet sensitive delivery dates. The components are available through Anritsu’s website, or through authorized distributors who are listed on Rohde and Schwarz’s website.

If unauthorized distributors were used, they would incur extra costs to the Government and would lead to a counterfeit risk.

3. MARKET SURVEY

Other equipment was researched. The Keysight N5183B (MXG) has an output power of up to 27 dBm (decibel-milliwatts) while the R&S SMB100B has an output power of 19 dBm to 34 dBm. While both have good spectral purity, having a higher upper limit on the output power allows to test signals that penetrate media such as ocean water. In addition, a higher power threshold has a greater signal range which is necessary for the BRR-6() system. Because of these factors, the R&S SMB100B was chosen over the Keysight

N5183B (MXG). Another signal generator that was investigated was the Berkeley

Nucleonics 845-M. The modulation capabilities on the Berkeley Nucleonics 845-M are limited than that of the R&S SMB100B. The Berkeley Nucleonics 845-M is capable of generating AM/FM waves while R&S SMB100B is able to generate AM/FM, pulse, and pulse train. The BRR-6() uses pulse trains transmit on a wide bandwidth and transited encoded messages. Because the R&S SMB100B has greater capabilities in modulation and output power, it was selected over the other investigated signal generators.
