• VNAs have become highly complex– Ideal for high-performance applications– Increases cost of VNA– Not easy to operate
• Many applications require only basic functions – Engineering – Manufacturing– Education
• Customers object to paying for unused – Advanced Features – Complicated Functionality

How did Anritsu achieve low cost?
• Patented ShockLineTM VNA on a chip architecture – Achieves microwave and millimeter-wave frequency
• Simplified internal architecture– Single board RF VNA implementation
• Eliminated front-panel and keypad– Not required for remote use applications
• Monitoring• Automation• Distance learning
– Flexibility to add displays / interfaces as required
• Focus on basic features and functions– Provide basic S-parameter measurements– Time domain

ShockLine Technology in action
• VectorStar based VNAs– MS4640B – 70 KHz to 70 GHz– ME7838A – 70 kHz to 145 GHz
• ShockLineTM series of VNAs– MS46322A: 1 MHz to 40 GHz– MS46122A: 1 MHz to 40 GHz

ShockLine Sampler based VNA
• Anritsu’s latest generation of VNA’s incorporate Non-Linear Transmission Lines– Also known as “Shocklines”
• Generate very narrow impulses – At microwave and millimeter wave frequencies
• For sampling receivers – To measure amplitude and phase of the VNA stimulus
• For power generation– Source and Rx LO

IVI-C Drivers
• Faster than SCPI– IVI driver interfaces directly with C dll for minimal programming overhead– Remote control speed improvement
• IVI-C package supports several programming languages and tools:– C#, .Net, MATLAB, LabView, LabWindows
• Requires V1.1.03 or later ShockLine software– Initial release supports subset of SCPI command functionality
• IVI-C package– Zip file containing .exe installation file on ShockLine product pages

easyTest SW
• Introduction – Allows faster development of factory and user
created wizards
• easyTest Creation – Experienced users can Create, Deliver, and Display
work instructions– Supports graphics, setups, step by step
instructions
• easyTest Execution – Work instructions make life easier for less-
experienced VNA users– More accurate testing and repeatable results – Less rework
