Cathode ray

• They travel linearly.
• They have a negative electric charge.
• They have particle property.
• Magnets can deflect them.
• Charge/mass ratio of the rays is constant.
• They travel from the cathode to the anode.
• Their properties are independent from the electrodes and gas present in the cathode ray tube.
• Cathode rays can ionize gas.

To test the properties of the particles, Thomson placed two oppositely-charged electric plates around the cathode ray. The cathode ray was deflected away from the negatively-charged electric plate and towards the positively-charged plate. This indicated that the cathode ray was composed of negatively-charged particles.

A cathode-ray tube is a device that uses a beam of electrons in order to produce an image on a screen. Cathode-ray tubes, also known commonly as CRTs, are widely used in a number of electrical devices such as computer screens, television sets, radar screens, and oscilloscopes used for scientific and medical purposes.

CRO displays the voltage signal as a function of time on its screen. The Time period of that periodic voltage signal is constant, but we can vary the number of divisions that cover one complete cycle of the voltage signal in the horizontal direction by varying the time/division knob on the CRO panel.

It consists of six parts namely heater, a cathode, a grid, a pre-accelerating anode, a focusing anode and an accelerating anode. In order to obtain the high emission of electrons the layer of barium oxide (which is deposited on the end of cathode) is indirectly heated at moderate temperature.

Digital oscilloscopes can be classified into four types:

• Digital storage oscilloscopes (DSO)
• Digital phosphor oscilloscopes (DPO)
• Mixed signal oscilloscopes (MSO)
• Digital sampling oscilloscopes.

The main part of CRO is CRT (cathode ray tube). This is reason why CRT is called the heart of CRO.

INTRODUCTION: The cathode-ray oscilloscope (CRO) is a common laboratory instrument that provides accurate time and aplitude measurements of voltage signals over a wide range of frequencies. Its reliability, stability, and ease of operation make it suitable as a general purpose laboratory instrument.

Difference Between An Analog Signal And Digital Signal. Difference Between Analog And Digital Integrated Circuits….Difference between CRO and DSO, Cathode Ray And Digital Storage.

We know that cathode ray oscilloscope(CRO) is an analog oscilloscope. Now we will compare CRO and DSO. As this is a digital world digital storage oscilloscope has more advantages over analog oscilloscope.

The Advantages of CRO One of the best advantages of CRO is that we can funnel website visitors to a specific goal, whether its physically or psychologically, to make a purchase or fill in a form. CRO makes your marketing strategy more effective and comprehensive by making the most of your website traffic.

The digital storage oscilloscope (DSO) is used to observe the radiation pattern generated by the transmitting antenna oscilloscope. The DSO used to save signals, so that it can be compared to or processed. The DSO can be used to measure the inductance, capacitor.

A DSO digitizes the analog input signal after which these signals are amplified if found to be weak. Once the amplification takes place, the signals are digitized which are further stored in a memory. These digital signals are processed by the analyzer circuit once the waveform is reconstructed.

DSO is a useful metric with which you can evaluate many critical business factors, like how quickly your customers are paying you, your firm’s liquidity, the sales made by your firm in a time period, the efficiency of your sales team, customer satisfaction, and customer retention.

The DSO is also one type of oscilloscope, used to display the waveform, but the difference between CRO and DSO is that in DSO, the digital signal is converted into analog and that analog signal will be displayed on the screen of the digital storage oscilloscope. A brief explanation about DSO is explained below.

Cathode Ray Oscilloscope (CRO) consists a set of blocks. Those are vertical amplifier, delay line, trigger circuit, time base generator, horizontal amplifier, Cathode Ray Tube (CRT) & power supply. The block diagram of CRO is shown in below figure. The function of each block of CRO is mentioned below.

DSO Full Form is Direct Sales Organization

Data is extracted from SAP R/3 system and loaded into Data Store Object. Initially, records are stored in New Status in the DSO. Records are stored in the New Table. Once the DSO data is activated, data is stored in the Active table.

10 useful ways to visualize your data (with examples)

1. Indicator. If you need to display one or two numeric values such as a number, gauge or ticker, use the Indicators visualization.
2. Line chart.
3. Bar chart.
4. Pie chart.
5. Area chart.
6. Pivot table.
7. Scatter chart.
8. Scatter map / Area map.

Change Log Table of DSO contains the log data of DSO. It contains the log of changed data within each request. One of the key fields of Change Log Table is “Request number for the data transfer field”. Write Optimized DataStore Objects only have one table which is Active Data Table.

The biggest difference between SAP’s earlier LSA and the above HANA LSA++ is the fact that queries can be directly built in BW on HANA on the DSO level and the additional layer of an Infocube/Multiprovider is not needed. This eliminates data redundancy and huge cost savings in terms of daily maintenance.

LSA ++ is a flexible consistent Data Framework virtually wrapped that consists of 5 main parts:

• EDW Propagation Layer.
• The Architected Data Mart Layer.
• Open Operational Data Store Layer.
• Agile Data Marts and BW workspaces.
• BW Virtual Data Mart Layer.

Open ODS views enable you to define data models for objects like database tables. The Open ODS view is a SAP BW∕4HANA metadata object that provides a structure description with attributes (fields) and data types. It represents a view on a source and adds analytic metadata to this source.

Advanced DSO (ADSO) is the primary artifact for persisting data in SAP BW 7.4 onwards. It combines functions from the Infocube/DSO and provides further enhancements such as modeling on Infoobjects as well on simple fields.

ADSO Model Templates are found on the right of the Modeling Properties screen. There are 3 Model Template categories, as we can see in Figure 1: Enterprise data warehouse architecture.

Adso is “tolerant of small children” like Jemmy.

Steps to create Corporate Memory ADSO in BW4 HANA

1. Create new Data source object (Advanced).
2. In general tab, select Data acquisition/corporate Memory – compression capabilities layer and click on Apply Template.
3. Activate the ADSO.
4. Creation of Transformation.
5. Create DTP under the created ADSO (CM)
6. DTP is created .
7. Setting under DTP . (
8. When you refresh your Info Area.

In BW4HANA system, ADSO (Advanced Data Store Object) is the primary persistent object used in data modelling. This blog explains the different tables created when using an ADSO and how a full/delta/initial load updates/fetches data from these different tables.

HANA studio is an Eclipse-based development and administration tool for working with HANA. It runs on Eclipse 3.6 platform. It is like Eclipse libraries which are used in implementation of scripts, ABAP, Java. To create tables and views, installion of Hana studio and Hana client is must.
