Exhibit 99.3

Subject:	Tektronix To Join Forces with Danaher Corporation
From:	Rick Wills, Tektronix President and CEO

Today, we announced Tektronix signed a definitive agreement to become a part of Danaher Corporation. Danaher is a multi-billion dollar corporation with business segments that include: Professional Instrumentation (including Electronic Test), Medical Technologies, Industrial Technologies, and Tools and Components. Tektronix will become part of the Electronic Test platform, and will operate as a stand-alone operating company, much as it does today.

I am very excited about this agreement and believe that this new relationship will accelerate our journey from being a very good company to an even better company. By joining forces with Danaher, we will be able to leverage each other’s strengths to make us an even stronger force in the market. Our solid market position, commitment to innovation and global distribution system will enhance Danaher’s strong leadership presence in the global test and measurement market. Our customers will benefit from the focused distribution channel that Fluke offers at the low end, our expertise at the high end, and our combined commitment to expanding our global reach, particularly in India and China. In addition, Danaher’s proven business management toolset will allow us to continuously improve productivity and will accelerate our ability to achieve greater leverage in our business model. As you know, this is a key focus area in FY08. Finally, this will further enable us to deliver on our commitment to provide our customers with the leadership products and global solutions to help them meet their technology and business needs.

I’ve spent a great deal of time considering all of the options for the future of the company. Tektronix will be a great fit with Danaher for a number of reasons. First and foremost, we share the same values. Danaher has a customer focused approach, a commitment to profitable growth, and a strong belief that the best team wins. We know that we have some of the best teams in the industry (YOU!) because we have been winning market share and the latest numbers prove it. In addition, Tektronix employees will be part of a much bigger company that has a proven track record for growth. Together, we should be able to offer expanded opportunities for employee training and development as well as the potential for career opportunities in other T&M product lines.

As you can imagine, there will be a lot of activity in the coming days and weeks as we work to close the deal and become part of the Danaher family. I know you will have a lot of questions and we will work very hard to ensure that we communicate everything we can as soon as we can. We have a series of meetings planned today and tomorrow in Beaverton and Richardson, where US-based employees can attend or call into the meetings (details below). If you are in an international location, your manager will be in touch with you soon, and we also have a number of site visits planned in many of the regional locations over the next few weeks. Rich McBee will represent me in Europe starting this week, and John Major will be traveling to China. I am planning several trips to Asia, including China, in the coming weeks. In many locations, a senior Danaher executive will also attend. Additionally, we have set up a link on TekWeb where you can submit any questions you might have on this topic. We will be monitoring your questions and will do our best to supply timely answers through your managers as we move through this process.

You can also access TekWeb to find out a little more about why I think this acquisition is such a great strategic fit for Tektronix.

Due to space limitations, please attend the meeting time and place assigned to your office building. Also, there is a limit to the number of dial-in callers that we can handle, so please attend in person if you are on campus.
