RECOMMENDATION AND DETERMINATION TO SOLICIT FROM ONE SOURCE

Sole Source:

I recommend that NASA, NASA Shared Services Center negotiate with Vendor only for Supply or Service.

The total estimated cost of this effort is dollar amount and the estimated period of performance or lead-time for delivery is Date.

OR

Brand Name Justification:

☒ I recommend that NASA, NASA Shared Services Center negotiate with only vendors who can provide the subject brand name from Tektronix for the MSO44B Oscilloscope and necessary accessories. The estimated period of performance or lead-time for delivery is 30 Business days.

This recommendation is for the acquisition of supplies or services determined to be reasonably available from only one source/only one manufacture. Competition is impractical for the following reasons (please answer the questions below):

1. What are the reasons for soliciting only the suggested source/suggested brand name? Please provide the unique characteristics of the items or services along with the supporting rationale and the market research performed to substantiate your reason for the suggested source/brand name.

Tektronix is recommended because the MSO44B provides an integrated mixed-signal platform with four Flex Channels, 1 GHz bandwidth, 31.25-million-point record length, eight-channel digital acquisition, and perpetual software for serial bus, jitter, eye-diagram, and power analysis. The TekVPI interface directly supports the specified current, differential, and active probes with automatic scaling and configuration, minimizing setup errors and preserving end-to-end bandwidth. Market research of comparable commercial systems found that alternatives would need multiple adapters, separate probe power supplies, reduced-capability probes, or additional software licenses to provide equivalent functionality.

2. What is the impact to the government if another vendor/brand is used? Include any dollar, schedule, or compatibility impacts if possible.

Another brand could require replacement probes, adapters, external power supplies, additional software, operator training, and revalidation of existing test procedures. These changes may reduce measurement bandwidth; increase noise, loading, timing skew, or scaling errors; and impair the accurate correlation of analog, digital, and current events. Selecting another vendor would delay the project schedule by four months. If this device cannot be procured, the resulting redesign would require additional labor and software training, increasing costs by more than $170,000.
