The Circuit Design Blog

In this tutorial video, we will demonstrate and compare the tools available in TINACloud for analyzing circuits in time domain. In TINACloud, you can analyze circuits in time domain, employing two different tools:

• Transient analysis from the Analysis menu of TINACloud.
• Simulated virtual oscilloscope from the T&M menu of TINACloud.

Transient analysis

The Transient analysis calculates the time response of circuits and presents the results as diagrams or text.

Select Transient from the Analysis menu of TINACloud, then press the Run button.

It is also important to select an option related to the Start condition.

For oscillators, like our circuit, the Zero initial values option applies. For amplifiers and many other circuits, you should use the default “Calculate operating point” option. You can refine the diagram in several ways. Here are a few:

• Zoom into any part of the diagram.
• Run cursors on the curves of the diagram.
• Calculate the frequency of the oscillation.
• Mark a period of the signal with the cursors.
• You can also find the Local or Global Minimum or Maximum by clicking the actual value field of a curve.
• You can also enter values to set the cursors more precisely, or
• add Labels to the curves showing the name of the related output on the circuit.
• Separate the curves or collect them in one diagram.
• You can insert the diagram into the schematics and save them together.

Simulated Virtual Oscilloscope

Now, let’s learn to operate the simulated virtual oscilloscope.

The simulated oscilloscope is very useful when you want to adjust some component values of small circuits and want to see the effect of the changes immediately, in order to fine-tune your circuit.

Invoke the oscilloscope from the T&M menu. After pressing the Run button the Out1 signal appears.

Use the controls to make the curve bigger and more detailed.

By default, the oscilloscope is in the “Auto” i. e., free running mode.

To get a steady state image you should enable triggering as follows:

Set the Trigger Mode to Normal

Set Trigger Source to Out1

Set the Trigger Level to 300m.

Consequently, the waveform is stabilized.

With the controls of the oscilloscope you can make a lot of changes on the displayed waveform. Here are a few:

By default, on the oscilloscope rising edge triggering is used, so the display starts when the signal rises above the Trigger level.

• You can also set this to falling edge triggering where the display starts when the signal falls below the Trigger level.
• You can also bring in the Vout signal by selecting Vout under Channel
• Finally, you can export the display into a diagram by pressing the Export to Diagram button under Data.

In this tutorial you can learn about how to use the virtual oscilloscope in TINACloud in Hebrew language.

We will analyze an oscillator circuit „Colpitts.tsc” which is included in the Example folder of TINACloud.

It is important to know that the simulated oscilloscope is very useful when you want to adjust some component values of small circuits and want to see the effect of the changes immediately, in order to fine-tune your circuit.

First, open the Colpitts. tsc from the File menu of TINACloud. After that invoke the Oscilloscope from the T&M menu. Then, press the Run button. The Out1 signal appears. Now, you can use the controls to make the curve bigger and more detailed.

By default, the oscilloscope is in the “Auto” i. e., free running mode. Therefore, we will show how to get a steady state image, as a result the waveform is stabilized.

We will also show how to switch the displayed signal into Falling Edge triggering, similarly how to bring in the Vout signal.

In addition, we will also explain how you can export the display into a diagram.

Finally, we will present how to fine-tune the circuit by changing the R resistor so that both Out1 and Vout are sinusoidal.

In this tutorial video, we present the DC current flow and voltage animation feature of TINACloud in Hebrew language through a DC example.

You can find the circuit “T-pad DC Animation.TSC” in the TINACloud example folder. T-pad is an attenuator circuit, but to demonstrate the animated currents and voltages we will use it with two voltage sources:

• one at its input
• and one at its output

In the given default circuit, the DC analysis will show just the currents of the resistors, displayed by the current meters.

To see the animated current we will show how to enable this feature in TINACloud.

After that we press the DC button the program will demonstrate the current flow with running dashes. As we can se the program also marks the direction of the currents with filled current arrows. When a current is zero, the current arrow is not displayed.

The value of voltages is also indicated by the color of the dashes (wires):

• Positive values are red,
• negative values are blue.
• and the zero voltage is marked by black

In addition, the program calculates the maximum voltages.

In conclusion, by using this tool you can make outstanding presentations showing animated current flows and voltages for your presentations, textbooks, or assignments.

In this tutorial video you can learn about how to use the virtual Oscilloscope in TINACloud.

In practice we very often use an oscilloscope to measure, analyze and debug circuits in the time domain. So, it seems obvious that a simulated virtual oscilloscope can be used in circuit simulation as well.

The simulated oscilloscope is very useful when you want to adjust some component values of small circuits and want to see the effect of the changes immediately, in order to fine-tune your circuit.

First, load the circuit Collpitts.tsc from the TINA Examples folder.

Next, invoke the Oscilloscope from the T&M menu, then press the Run button.

As you can see the Out1 signal appears.

You can use the controls to make the curve bigger and more detailed.

By default, the oscilloscope is in the “Auto” i. e., free running mode.

To get a steady state image you can enable triggering as follows:

1. Set the Trigger Mode to Normal
2. Set Trigger Source to Out1
3. Set the Trigger Level to 300m.

With the controls of the Oscilloscope you can make a lot of changes on the displayed waveform. For example you can change the default rising edge triggering into falling edge triggering. You can also bring in the Vout signal or export the display into a diagram.

We will also present how to fine-tune your circuit.

Good news! As a 2020 holiday gift we have added Current flow and voltage animation to TINACloud. 
And yes, the same feature will be also available next year in the offline versions of TINA.

Current and voltage animation is an especially useful pedagogical tool. You can make outstanding presentations showing animated current flows and voltages for your presentations, textbooks, or assignments.

In this tutorial video, we demonstrate the DC current flow and voltage animation feature of TINACloud.

We present this through a DC example included in TINACloud.

To see the animation feature, first we have to enable it in the Options dialog under the Analysis menu.

Next, we click the DC button.

The program will demonstrate the current flow with running dashes. The program will also mark the direction of the currents with filled current arrows.

The color of the dashes also indicates the value of voltages. Positive values are red, and negative values are blue. When the voltage reaches zero the color turns black.
