The programs can be changed, as required by user, easily. In other case we have to replace hardware to fulfill our new need. User is able to analyze acquired data in more detailed and friendly manner. Required characteristics can also be analyzed with the help of graphs.

Readings can also be stored in files in PC. Table of contents 1 Keithley A source meter 2 Requirement of interfacing 3 Virtual instrumentation? For system level applications, the Series A's Test Script Processor TSP architecture, along with other new capabilities such as parallel test execution and precision timing, provides the highest throughput in the industry, lowering the cost of test.

For bench-top use, Series A instruments feature an embedded TSP Express Software Tool that allows users to quickly and easily perform common I-V tests without programming or installing software. Requirement of interfacing for keithley source meter If a need arises to extend the set of functions of source meter, it can be done cost effectively and easily by software running on the PC processor. Results can be displayed in desired format on front panel of labview for example in table, graph, etc.

I-V characteristics can be analyzed by plotting current and voltage on X-Y Graph simultaneously. Importance and significance of virtual instruments With virtual instruments, engineers and scientists build measurement and automation systems that suit their needs exactly user-defined instead of being limited by traditional fixed- function instruments vendor-defined.

You can adapt a virtual instrument to your particular needs without having to replace the entire device because of the application software installed on the PC and the wide range of available plug-in hardware. A traditional instrument might contain an integrated circuit to perform a particular set of data processing functions; in a virtual instrument, these functions would be performed by software running on the PC processor. You can extend the set of functions easily, limited only by the power of the software used.

By employing virtual instrumentation solutions, you can lower capital costs, system development costs, and system maintenance costs, while improving time to market and the quality of your own products. Remote operation Keithley Instruments Test Script Processor TSP enabled instruments operate like conventional instruments by responding to a sequence of commands sent by the controller. You can send individual commands to the TSP-enabled instrument the same way you would using any other instrument.

Unlike conventional instruments, TSP-enabled instruments can execute automated test sequences independently, without a controller. You can load a series of remote commands into the instrument and store these commands as a script that can be run later by sending a single command message to the instrument. You do not have to choose between using conventional control or script control.

You can combine these forms of instrument control in the way that works best for your particular test application. It is capable of running code written in a scripting language called Lua.

Lua is referred as the Test Scripting Language for this instrument. What is a script? A script is a collection of instrument control commands and programming statements.

Scripts that you create are referred to as user scripts. Your scripts can be interactive. Interactive scripts display messages on the front panel of the instrument to prompt the operator to enter parameters. Command reference There is a huge collection of remote commands to control the instruments. It is classified in groups according to their functions or in alphabetical order. Example of commands:- -- to source a voltage of 10 volts across DUT on channel A smua.

In contrast to text- based programming languages, where instructions determine program execution, LabVIEW uses dataflow programming, where the flow of data determines execution. The user interface is known as the front panel. You then add code using graphical representations of functions to control the front panel objects.

The block diagram contains this code. In some ways, the block diagram resembles a flowchart. Why Labview? Labview is an integral part of virtual instrumentation because it provides an easy-to-use application development environment designed specifically with the needs of engineers and scientists in mind. LabVIEW offers powerful features that make is easy to connect to a wide variety of hardware and other software.

We can customize front panels with knobs, buttons, dials and graphs to emulate control panels of traditional instruments, create custom test panels, or visually represent the control and operation of processes. There is a program for each type of sourcing. Types of source input are:- 1. Voltage across DUT 2. Current through DUT 3. Resistance of DUT 4. Bias source A constant voltage of desired amount is sourced to the DUT by inserting the value through front panel. Number of readings taken is also decided by the user.

Default is 1. Type of source and measure are selected from options in combo boxes. Case 1 Front panel Here the readings are taken across resistor of ohm. A source voltage of 5 volts is given and the measurement is done 5 times. All measurements are shown in table and they are also stored in PC in the folder specified by user. Block diagram Linear staircase sweep source this sweep type steps from a start voltage or current value to an ending stop value.

A measurement is made at each point after source and measurement settling time. Case 2 A linear staircase sweep is configured using a start level, a stop level, and the total number of points, including the start and stop points. When the sweep starts, the output will go to the start source level.

The output will then change in equal steps until the stop level is reached. Front panel Here readings are taken around a ohm resistor. Voltage is sourced from 1. Current values through the DUT are measured at every step.

Readings are also stored in specified folder in PC with the help of icon write to spreadsheet file. Graph of source values, measure values and I-V characteristics can also be observed. Block diagram Logarithmic staircase sweep This type of sweep is similar to the linear staircase sweep. The steps, however, are done on a logarithmic scale. Like a linear staircase sweep, logarithmic sweeps are configured using a start level, stop level, and the number of points.

The step size is determined by the start and stop levels, and the number of sweep points. However, in a logarithmic sweep step size increases or decreases exponentially. An asymptote is used to change the inflection of a sweep curve and allow it to sweep through zero. The five log steps for this sweep are listed in the Logarithmic sweep points table below. When this sweep starts, the output will go to the start level 1 V and sweep through the symmetrical log points.

Front panel Block diagram Pulsed linear staircase sweep Pulsed linear staircase sweeps function the same way that DC linear staircase sweeps function, except pulsed linear staircase sweeps return to the idle level between pulses.

Case 4 Front panel Block diagram Pulsed logarithmic staircase sweep Pulsed logarithmic staircase sweeps function the same way that DC logarithmic staircase sweeps function, except pulsed logarithmic staircase sweeps return to the idle level between pulses. Front panel Block diagram Conclusion The five cases for testing and analysis of semiconductor devices by sourcemeter by sourcing and measuring can be done easily by just entering the details.

Results are expressed in all required formats and can also be saved in specified folder in PC. This is much more efficient, flexible and user friendly than performing the experiment without interfacing. Learn more about Scribd Membership Home. Much more than documents.
