3.10.10.1 Loading and saving the arbitrary function
The100sequencesofthearbitraryfunction,whichcanbemanuallyconguredwiththecontrolpanelofthede-
vice and which are applicable either to voltage (U) or current (I), can be saved to or loaded from a common USB
stickviathefrontsideUSBport.Generally,all100sequencesaresavedorloadedusingatextleoftypeCSV
(semicolon separator), which represents a table of values.
In order to load a sequence table for the arbitrary generator, following requirements have to be met:
• The table must contain exactly 100 rows with 8 subsequent values (8 columns, separated by semicolons) and
must not have gaps
• ThelesmustbestoredinsideafoldercalledHMI_FILESwhichhastobeintherootoftheUSBdrive
• ThelenamemustalwaysstartwithWAVE_UorWAVE_I(notcase-sensitive)
• Values with decimal places must use the comma as decimal separator
• Allvaluesineveryrowandcolumnhavetobewithinthespeciedrange(seebelow)
• Thecolumnsinthetablehavetobeinadenedorderwhichmustnotbechanged
Followingvaluerangesaregivenforuseinthetable,relatedtothemanualcongurationofthearbitrarygenerator
(column headers like in Excel):
Column Parameter Range
A ACs 0...50% U or I
B ACe 0...50% U or I
C S.Freq 0...10000 Hz
D E.Freq. 0...10000 Hz
E Winkel 0...359 °
F DCs 0...(Nominal value of U or I) - ACs
G DCe 0...(Nominal value of U or I) - ACe
H Time 10...36.000.000.000μs(36billionμs)
For details about the parameter and the arbitrary function refer to „3.10.10. Arbitrary function“.

► How to load a sequence table (100 sequences) from a USB stick:
1. Do not plug the USB drive yet or remove it.
2. Access the function selection menu of the function generator with MENU
-> Page 2 -> Function Generator -> Page 2 -> Arbitrary -> U/I, to see the
main screen of sequence selector, as depicted to the right.
3. Tap touch area , then and follow the instructions on
screen.Ifatleastonevalidleshasbeenrecognized(forleandpath
namingseeabove),thedevicewillshowalistoflestoselect
from with .
4. Tap touch area inthebottomrightcorner.Theselectedleisthencheckedandloaded,ifvalid.
Incaseitisnotvalid,thedevicewillshowanerrormessage.Thenthelemustbecorrectedandthe
steps repeated.
