3.8.10.1 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device
andwhichareapplicableeithertovoltage(U)orcurrent(I),canbesavedtoorloadedfromacommonUSBash
drive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 AC Start 0...50% U or I
B AC End 0...50% U or I
C Frequency Start 0...1000 Hz
D Frequency End 0...1000 Hz
E Start angle AC 0...359°
F DC Start 0...(Nominal value of U or I) - AC Start
G DC End 0...(Nominal value of U or I) - AC End
H Timeinμs 100...36.000.000.000(36billionμs)
For details about the parameter and the arbitrary function refer to „3.8.10. Arbitrary function“.
Example CSV:
Theexampleshowsthatonlythersttwosequencesarecongured,whileallothersaresettodefaultvalues.The
table could be loaded as WAVE_U or WAVE_I when using, for example, the model PSI 9080-120 2U, because the
valueswouldtboth,voltageandcurrent.Thelenaming,however,isunique.Alterpreventsyoufromloading
aWAVE_Ileafteryouhaveselected“Arbitrary-->U”inthefunctiongeneratormenu.Thelewouldnotbelisted
as selectable at all.
► How to load a sequence table (100 sequences) from a USB ash drive:
1. Do not plug the USB drive yet or remove it.
2. Access the function selection menu of the function generator with
MENU -> Function Generator -> Arbitrary.
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.
