I have some questions about the wave generator software (PCLab2000SE). I’m using the function generator PCGU1000:
Is it possible to create functions with a positive slope for 10 minutes (start at zero), 30 minutes a constant value and after this 5 minutes with a negativ slope back to zero?
What is the function of the checkbox “Repetition interval”?
I’ve created a .lib file like this: 1 1200 -1.5 7.5 30
2 400 1.0 6.0 60
But after opening this file I got this error message: “Error found in data file”. I think my file is equal to the help example.
Yes this is possible using the library waveform.
Please see the Help / Wave Editor how to create the .LIB file.
[quote]positive slope for 10 minutes (start at zero), 30 minutes a constant value and after this 5 minutes with a negativ slope back to zero[/quote]The .LIB file for this operation is:
0.0
(10)
1.0(30)
(5)
0.0
In normal mode the lowest frequency is 10mHz.
To get the period of 45 minutes you have to use the sweep function.
Select “More Funct.” button.
Select “Sweep” button.
There you have to check the “Sweep selected waveform” check box.
Then select the “LIB” button and open the .LIB file.
Now select again the “Sweep” button.
Set the start and stop frequency: 0,00037037 Hz.
Set the sweep time to maximum value 200000 Sec.
Click “Start Sweep”.
The wave will be repeated after 45 minutes.
You can use the Tools / Wave Editor to create the .LIB file.
[quote]What is the function of the checkbox “Repetition interval”?[/quote]Quote from Help:
[size=85]You may use Repetition interval setting to repeat one cycle of signal waveform with selectable interval.
Click More Funct button, check the Repetition interval check box and then enter the interval time in milliseconds and press Enter.
Repetition is usable for all the waveforms except for noise and sweep. Uncheck the Repetition interval check box or enter interval 0 to exit repetition mode.[/size]
