Using Calibration to Optimize Performance in Crucial Measurements
The Seattle weather was unexpectedly great for IMS2013, sunny and clear all week. The venue was very good but the 2 room setup was far from ideal for the exhibition and some people did not even know there was a second room attached in the back left corner. So it is not surprising that the traffic in the back room seemed to be a step below that in the front but still respectable. While the attendance did not seem overwhelming, there was some optimistic pockets of activity and many were satisfied with the high quality of the attendees.
Here a summary of the products from the exhibition for all of the companies our editors were able to visit during the event.
Test and Measurement:
Agilent Technologies demonstrated 25 of its newest design and measurement solutions, covering everything from circuit-level modeling through system verification for general RF, microwave, 4G communications and aerospace/defense.
