How to save a sequence point table to a USB stick:
1.
Do not plug the USB stick yet or remove it.
2.
While the DC terminal is switched off, tap on
to access the function selection menu. There ap on
group “Arbitrary” which will show the settings as shown in the screenshot to the right.
3.
Swipe up to go down to the “Sequence setup” part and tap on
Import/Export
, then on
Save
and follow
the instructions. In the file open dialog you can either select an existing file, if at least one compatible file is
listed, or you can create a new one by not selecting any file.
4.
Save the file, new or overwriting, with
.

Ramp function
Restrictions which apply particularly to this function:
•
There is no preselection to which of both, source mode and sink mode, the function is applied; the settings decide
whether it’s “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
setting “I Sink” is not 0
The following parameters can be configured for a ramp function:

0...U

or
-I

...+I
Nom
Start/end point of the ramp. Both values can be equal or different,
which then results in either a rising, falling or horizontal ramp
Time t1
0.1 ms...36,000,000 ms
Time before ramp-up or ramp-down of the signal.
Time t2
0.1 ms...36,000,000 ms
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.

This function generates a rising, falling or horizontally running
ramp between the start and end values over time t2. Time t1
creates a delay before the ramp starts.
The function runs once and stops at the end value. To have a
repeating ramp, the Trapezoid function would have to be used
instead (see
3.11.8
).
Important to consider are the static values of U or I which define
the start level before the ramp generation. It’s recommended
that the corresponding static value is set equal to value
Start
,
unless the load at the DC output (source mode) shall not be
provided with a voltage before the actual start of the ramp (time
t1) or the external source shall not yet be loaded with a current
in sink mode. In that case the static value should be set to zero.
