► How to load a curve data le for MPP4
1. While theDC terminal isswitched o󰀨,enter the MENU and the Function Generator and access MPP
Tracking.
2. In the screen switch to tab MPP4. In the lower part a button labelled Import/Export will appear. Tap it.
3. In the next screen tap on LOAD MPP4 voltage values from USB, have your USB stick ready and follow
the instructions.
3.11.17.6 Save result data from MPP4 mode to USB stick
After the MPP4 function has run through, the result data can be saved to USB stick. The device will always save 100
data sets consisting of the actual values of voltage, current and power belonging to the points it has run through.
There is no extra numbering. In case the settings Start and End were not 1 and 100, the true result data can later
belteredfromthele.Pointswhichwherenotadjustedareautomaticallysetto0V,thusit’sveryimportantto
carefully adjust start and end point because with a voltage setting of 0 V an electronic load would draw its rated
current. That’s because in this mode, current and power are always set to max.
Formatoftheresultdatale(fornamingconventionseesection1.9.6.5):
Legend:
• Column A: actual voltage of points 1-100 (= U
MPP
)
• Column B: actual current of points 1-100 (= I
MPP
)
• Column C: actual power of points 1-100 (= P
MPP
)
• Rows 1-100: result data sets of all possible curve points
The values in the example table to the left are
with physical units. If that’s not wanted, they
can be turned o in the “General settings” of
the device with parameter “USB logging with
units (V,A,W)”.
► How to save a curve data le for MPP4
1. After the function has run through, it will stop automatically. Tap on the RETURN button to go back to the
MPP4congurationscreen.
2. Tap on the button labelled Import/Export.
3. In the next screen tap on SAVE MPP4 results to USB, have your USB stick ready and follow the instructions.
Youwillhavethechoicetoeitheroverwriteanyofthedisplayedlesortocreateanewonebytappingon

3.11.18 Remote control of the function generator
Thefunctiongeneratorcanberemotelycontrolled,butcongurationandcontrolofthefunctionswithindividual
commandsisdi󰀨erentfrommanualoperation.Theexternaldocumentation“ProgrammingGuideModBus&SCPI”
on the included USB stick explains the approach. In general the following items apply:
• The function generator isn’t directly controllable via the analog interface; the only impact to the function run can
comefrompinREM-SBswitchingtheDCterminalo󰀨,whichwillpausethefunction,soitcouldcontinuelater
with pin REM-SB switching the DC terminal on again and in case the function hasn’t been stopped otherwise.
• The function generator is unavailable if R mode (resistance) is activated
