                     TEKTRONIX PROVIDES GUIDANCE ON EARNINGS
             IMPACT RELATED TO THE ACQUISITION OF INET TECHNOLOGIES

                       REITERATES PRE-ACQUISITION GUIDANCE

BEAVERTON, Ore., November 19, 2004 - Tektronix, Inc. (NYSE: TEK), a leading
worldwide provider of test, measurement, and monitoring instrumentation, today
provided guidance on the earnings impact of its acquisition of Inet
Technologies, Inc., a leading global provider of communications software
solutions that enable next-generation networks, including 2.5G and 3G mobile
data and voice-over-packet (VoIP) technologies, and traditional networks.

For the second quarter of its fiscal year, which ends November 27, 2004,
Tektronix' financial results will include the consolidation of the business
results from the Inet acquisition for the months of October and November, 2004.
The company anticipates the incremental impact of the acquisition to be $.02 -
$.04 dilutive to second quarter earnings per share, excluding the mostly
non-cash expense of the one-time write off of in-process research and
development (R&D) and other acquisition related charges. The total impact of
these expenses in the second quarter of the fiscal year will be $.40 - $.45 per
share. Of this, roughly $.35 per share relates to the one-time, non-cash write
off of in-process R&D.

For the full fiscal year, the incremental impact of the acquisition is expected
to be slightly dilutive, excluding the mostly non-cash impacts of the one-time
write off of in-process R&D and other acquisition related charges.

"We are now nearly sixty days into the integration and we are excited about the
opportunity created by this acquisition and the potential we see in the
synergies between our mobile protocol test products and the network management
and diagnostic products gained from the acquisition," said Rick Wills, Tektronix
Chairman and CEO. "This combination should enable us to grow our leadership
position in these markets as we gain a unique insight into the end-to-end needs
of network operators and equipment manufacturers seeking to implement
next-generation technologies such as General Packet Radio Service (GPRS),
Universal Mobile Telecommunications Systems (UMTS), and VoIP."

The company reiterated its original guidance for the second quarter of the
fiscal year of $.30 - $.35 earnings per share, excluding business realignment
and one-time items, and the impact of the Inet acquisition.

Tektronix will release its second quarter fiscal 2005 earnings results and hold
its investor conference call on December 16, 2004.
