Installation Proces:


This chapter provides information for the initial inspection and preparation for use of the ShockLine MS46122A/B Series VNA and includes information on instrument installation, loading ShockLine Software, required operating environment, power requirements, and initial inspection. After power up, the various power modes are described with general warm-up and calibration time intervals. The preventive maintenance section includes information on cleaning along with preparation for storage or shipment.


                       Unpacking the Product

Initial Inspection

Inspect the shipping container for damage. If the container or cushioning material is damaged, retain until the contents of the shipment have been checked against the packing list and the instrument has been checked for mechanical and electrical operation. If the ShockLine MS46122A/B Series VNA is physically damaged, notify your local sales representative or Anritsu Customer Service. If either the shipping container is damaged or the cushioning material shows signs of stress, notify the carrier as well as Anritsu. Keep the shipping materials for the carrier’s inspection.

Preparation for Use

The ShockLine MS46122A/B Series VNA requires software installation. To interface with the instrument through direct manual control, a PC running Windows 7 or higher with keyboard, mouse, monitor or touchscreen, ShockLine software, and interfacing USB cable are required.


                       Operating Environment and Power Requirements

Before  installing the  ShockLine MS46122A/B  Series VNA  in its operating  environment, ensure  airflow passages around the instrument are clear. Proper ventilation is of particular importance whenever the unit is being rack mounted. The ShockLine MS46122A/B Series VNA can be operated within the following environmental limits:

Multimedia Learning (ICT Classroom):

Introduction:  In this, the teacher will deliver some concepts with the aid of Software tools. These learning tools play a vital role in delivering subject knowledge. The students can identify the key points of the presentation in an easy way. Live demonstration can be an effective tool to present material in the classroom and encourage student learning. Multimedia combines basic types of media into a learning environment such as text, audio, video and graphics thus providing a powerful tool for teaching. This allows the students to pay more attention towards the concepts. It also helps the students to think and analyze the concepts in a better way.  Execution Plan:  The teacher explains some topics in their regular teaching process using Software Tools /Animation / Videos to simplify their presentation.  Outcomes:  1. Simple way of presenting subject knowledge than from the regular teaching practices.  2. Students can understand the concepts in a better way. Google Classroom User Manu

Civil Engineering : Project Based Learning

Method: Project work and Report writing The department has made it a mandatory requirement for every student to design and conduct a project, right from the fifth semester onwards which is beyond the regular curriculum for the semester. This helps the student to have a hands-on approach to the engineering design process and utilize the theoretical aspects they have learnt to develop prototypes and design experiments on what they have learnt. During the fifth semester, the students conduct a mini-project that focuses on the fundamental software design aspects of computer Science and Engineering. A project group consisting of a maximum of four members under the guidance of a faculty member explores a scientific principle related to their area of interest. The learning process is given more weightage during the assessment and not the results obtained.  Students in their sixth semester are encouraged to do a project which will help them to learn new technical skills with guidance from an a

Brainstorm Brigade

  Group Discussion among the students Group discussions can be a powerful learning tool for students, as they offer several advantages and benefits. Here are some of the most significant impacts of group discussions: Improved Communication Skills: Group discussions provide students with an opportunity to express their thoughts and ideas in a collaborative environment. Through active listening and respectful communication, students can enhance their communication skills, including clarity, concision, and persuasion. Enhanced Critical Thinking: Group discussions encourage students to think critically and examine multiple perspectives on a particular topic. By engaging in constructive dialogue and debate, students learn to analyze and evaluate information, challenge assumptions, and develop reasoned arguments. Increased Engagement and Participation: Students who participate in group discussions are more engaged and invested in th
