Introduction
This page will show you how to use the quick functions to easily use your TiePie engineering measuring instrument as different virtual instruments: oscilloscope, spectrum analyzer, transient recorder or voltmeter.
The quick functions can be accessed via the main menu and the quick functions toolbar.
Available functions
The easiest way to use the quick functions, is to use the buttons on the quick functions toolbar, but they can also be accessed via the main menu.
The available quick functions are listed in the following table.
| Icon | Action | Short description |
 |
Create Yt graph | Create a Yt graph for the active instrument |
 |
Create XY graph | Create an XY graph for the active instrument |
 |
Spectrum analyzer | Create a spectrum graph for the active instrument |
 |
Transient recorder | Set the active instrument to streaming mode and make a transient graph |
 |
Create voltmeter | Create a voltmeter for the active instrument |
An example of each function is given in the following sections. A Handyscope HS3 is used, but other instruments supported by the Multi Channel software can also be used.
Oscilloscope
An oscilloscope can be used to display measurements against time ( Yt mode ) or to display one channel against another ( XY mode ). You can manually set a graph to either Yt or XY mode, and drag the desired channels into the graph, or you can use the Yt or XY quick functions.
Information about using graphs can be found in the graph section. To learn more about basic measurements, read the digital data acquisition page and the triggering page.
Yt mode
To use the active measuring instrument as an oscilloscope in Yt mode, click the
button on the toolbar.
The channels of the active instrument will be shown in an empty graph. A new graph will be created when no empty graph is present.
XY mode
To use the active measuring instrument as an oscilloscope in XY mode, click the
button on the toolbar.
Channels 1 and 2 of the active instrument will be shown in an empty graph. A new graph will be created when no empty graph is present.
This function is disabled when the active instrument has less than two channels.
Spectrum analyzer
To use the active measuring instrument as a spectrum analyzer, click the
button on the toolbar.
An FFT object will be created and connected to each channel of the active instrument. The FFT objects convert the measured time base signals to a spectrum by means of a Fast Fourier Transform. The outputs of the newly created FFT objects will be shown in an empty graph. A new graph will be created when no empty graph is present.
Transient recorder
To use the active measuring instrument as a transient recorder, click the
button on the toolbar.
The active instrument will be set to streaming mode and a data collector object will be created and connected to each channel of the active instrument. The outputs of the newly created data collector objects will be shown in an empty graph. A new graph will be created when no empty graph is present.
The transient recorder is usually used for relatively slow signals. The instrument is set to streaming mode. The advatages over normal scope mode operation are:
- The measurement display is constantly updated during the measurement. You don't have to wait until the whole measurement is completed to see the result.
- Longer measurements are possible than would fit in the instrument's memory in normal scope operation.
Voltmeter
To use the active measuring instrument as a voltmeter, click the
button on the toolbar.
The channels of the active instrument will be shown in a newly created meter object.
By default, the measurements "Mean" and "RMS" are enabled. Other measurements can be added for each channel. Examples are: minimum, maximum, top-bottom, variance, standard deviation, frequency and for frequency data: Total Harmonic Distortion.
