Documentation/ISTA User's Manual of 132

The content range contains a settings group for each of the signal sources, i.e. direct voltage,

generator, direct current and simulator.

The settings for "Amplitude", "Frequency", "Sample ratio" and "Resistor" consist respectively of a

display range for the set value and two arrow keys left and right, with which you can adjust the

signal. The longer you hold the arrow key down, the faster the signal value changes.

The setting "Signal" provides a separate button for the "Rectangular" and "Sinusoidal" signal

types.

Select a signal by clicking its heading. It is not possible to make a multiple selection.

If you switch to Multimeter or Oscilloscope and then return to Signals, then the most recent setting

is retained. However, if you quit the Measuring instruments and then call up Signals again, then the

settings will be reset to the default values.

The buttons in the action line have the following functions:

◊ Start/Stop: Transmits the set signals to the IMIB. In the message line, a message appears,

indicating that the signals are active. When you click the button a second time, you switch

the signals off again.

◊ Exit measuring devices: Switches active signals off, sets the measuring instruments back

to the IMIB, and returns to the "Measuring instruments" tab.

► How to set direct voltage or direct current:

◊ Click the name of the signal source: "Direct voltage" or "Direct current".

◊ Select a value in the appropriate signal source with the arrow keys.

◊ Click the "Start/Stop" button.

◊ When you wish to terminate the signal feed, click "Start/Stop" again.

► How to adjust the alternating current generator:

◊ Click the name of the signal source: "Generator".

◊ Select the signal form: "Rectangular" or "Sinusoidal".

◊ Set the amplitude and frequency with the respective arrow keys.

◊ If you have selected the "Rectangular" signal form: Set the sampling rate with the

corresponding arrow keys.

◊ Click the "Start/Stop" button.

◊ When you wish to terminate the signal feed, click "Start/Stop" again.

► How to simulate a resistance:

◊ Click the name of the signal source: "Simulator".

◊ Set the desired resistance with the corresponding arrow keys. The permissible resistance

values are displayed in the window.

◊ Click the "Start/Stop" button.

When you wish to terminate the signal feed, click "Start/Stop" again.
