How to load a sequence table from an 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 -> Function Generator -> Arbitrary -> U/I, to see the main screen
of sequence point selector, as depicted to the right.
3.
Tap touch area
, then
and follow the instructions
on screen. If at least one valid files has been recognized (for file and
path naming see above), the device will show a list of files to select
from with
.
4.
Tap touch area
in the bottom right corner. The selected file is then checked and loaded, if
valid. In case it is not valid, the device will show an error message. Then the file must be corrected and
the steps repeated.

2.
Access the function selection menu of the function generator via MENU -> Function Generator -> Arbitrary
3.
Tap on
, then
. The device will request you to plug the USB stick now.
4.
After plugging it, the device will try to access the stick and find the folder HMI_FILES and read the content.
If there are already WAVE_U or WAVE_I files present, they will be listed and you can either select one for
overwriting with
, otherwise select
for a new file.

3.11.11 Ramp function
The following parameters can be configured for a ramp function. Following applies:
•
There is no preselection to which of both, source mode and sink mode, the function is applied to; the settings
decide whether it is “source mode only”, “sink mode only” or a mixture of both
•
When applying the function to the voltage, the device can only switch to and work in sink mode if the external
voltage on the DC terminal is higher than the highest point ( amplitude) of the wave and the current set
-
ting “I Sink” is not 0

t1
0,1 ms...36000 s Time before ramp-up or ramp-down of the signal.
t2
0.1 ms...36000 s Ramp-up or ramp-down time
10 h after reaching the ramp end, the function will stop automatically (i.e. I = 0 A, in case the
ramp was assigned to the current), unless it has been stopped manually before.
