September 25, 2008 PXI Modules Provide Higher Frequencies, Speed, And Flexibility
At last month’s NIWeek conference in Austin, Texas, National Instruments introduced several RF products that are sure to be a hit with some engineers because of their higher frequency range, faster speeds, and lower costs. With RF testing becoming a larger part of the design and production testing of wireless technologies, these devices could yield faster time-to-market while decreasing test costs. NI also rolled out a line of Wi-FI testers...

Handheld Real-Time Spectrum Analyzers Nail Interfering Wireless Signals Fast
Complex wireless technologies make measurement a real challenge with their short bursts and non-deterministic timing. Furthermore, identifying and locating interfering RF emitters that are misusing the radio spectrum has become more of a challenge. Yet Tektronix’s SA2600 and H600 Hawk Real-Time Spectrum Analyzers can meet both of these measurement challenges.

MELs Make Power-Source Testing Faster And Easier
How do you test a very high-current and/or high-voltage power source? You measure the voltage, current, and power, but you need to test the source under typical and maximum load conditions. So what do you use for a load, especially if it must dissipate up to tens of kilowatts? The MEL series of modular electronic loads from PPM Inc. can handle up to 60 kW in one 8-ft rack.

Handbook Provides The Fundamentals Of Switching In Test Systems
Most test systems today require switching to reconfigure the test setup to make multiple different tests and measurements. This isn’t something you learn in school. Fortunately, Keithley Instruments’ Switching Handbook: A Guide to Signal Switching in Automated Test Systems consists of up to 180 pages of practical tutorial information on how to set up and optimize switching test systems.

Embedded Waveform Viewing Improves Signal Integrity Testing Without An Oscilloscope
Buses and backplanes keep getting faster. Ethernet now runs at 10 Gbits/s, and the XAUI interfaces are at 3.125 and 6.25 Gbits/s. Blade server serial buses like PCI Express are moving from 2.5 to 5 Gbits/s. The SAS and SATA interfaces are increasing from 1.5 to 3.0 to 6.0 Gbits/s. Fibre Channel is now at 8 Gbits/s. And, digital video is increasing from 1.5 to 3.0 Gbits/s as 1080p HDTV becomes more popular.

SATA Gen-2 PHY Compliance Test Framework And Software Shortens Test Time By 70%
The latest generation of Serial ATA (SATA), the serial interface for disk drives (Gen-2), now runs at 3 Gbits/s. To meet the compliance requirements known as the Methods of Implementation (MOI) of the SATA-IO working group, a new product has to pass 153 specific tests. These tests are complex and time consuming, and they add extra cost to every new product manufactured. Tektronix is addressing this challenge with its TekExpress SATA Gen-2 test package.

February 14, 2008 Oscilloscope Software Automatically Detects Hidden Waveform Anomalies
All digital oscilloscopes come with their own measurement and analysis software to perform basic and advanced tests and measurements. You can also get a great thirdparty scope analysis software package from Amherst Systems Associates (ASA Corp.). Known as the M1 Oscilloscope Tools, it runs on virtually any modern digital sampling scope from Agilent, LeCroy, Tektronix, or Yokogawa. The software offers measurement workflow automation and built-in...
