  37. Agilent 16800 vsTekTLA6400 (Con’t) • New TLA6400 Series Overview • Tek discontinued TLA5000B and TLA6200 Series LAs, new TLA6400 Series introduced on 21st Aug. • The TLA6400 is a repackaging of detuned TLA7BB logic analyzer module(s) and TLA7012 frame into a single monolithic instrument. • There is no new measurement technology or software features associated with this introduction. • This is similar to Tek’s TLA6200 series logic analyzer announcement (September 2010) which has not been successful to date. • The frame CPU and operating system have been upgraded (Windows 7 64-bit operating system). • Feature wise this product competes with Agilent’s 16950B modular logic analyzer. Agilent Confidential Agilent Confidential • Lead with Agilent’s 16800 LA differentiators to avoid deep discounts: • ONLY 204-channel portable logic analyzer. • ONLY portable logic analyzer with built-in 48-channel pattern generation. • ONLY portable logic analyzer with 2 independent analyzers (available on six models >34 channels). • Digital VSA – Lock-out application. Perform time, frequency & modulation domain analysis on digital baseband & IF signals. • FPGA Dynamic Probe – Best in class FPGA debug with automated bit map-ping. • Eye Scan – simultaneous eye diagrams across all signals (best used at clock rates >200 MHz). • Viewscope– No need for expensive cable to integrate time-correlated scope traces into logic analyzer waveform display.

  39. Considerations When Configuring a Logic Analyzer • The key questions to ask when configuring a logic analyzer • What kind of application?  Distinguish either Logic Analyzer or Protocol Analyzer • How do you intend to probe your signals?  Probing options • What are the signal speeds you want to capture?  State/Timing speeds • What is your maximum number of signal/channel?  Number of channels • How much data do you need to see?  Memory depth
