► How to save a sequence table (100 sequences) to a USB stick:
1. Do not plug the USB stick yet or remove it.
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.

3.9.11 Ramp Function
Thefollowingparameterscanbeconguredforarampfunction.
Value Range Description
Ustart / Istart 0...Nominal value of U, I Start value (U,I)
Uend / Iend 0...Nominal value of U, I End value (U, I)
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
Schematic diagram: Application and result:
A.start
t
A
t1 t2
A.End
This function generates a rising or falling ramp between start
and end values over the time t2. Time t1 creates a delay before
the ramp starts.
The function runs once and stops at the end value.
ImportanttoconsiderarethestaticvaluesofUandIwhichdene
the start levels at the beginning of the ramp. It is recommended
that these values are set equal to those in A.start, unless the load
at the DC output should not be provided with voltage before the
start of the ramp. In that case the static values should be set to
zero.
10h after reaching the ramp end, the function
will stop automatically (i.e. I = 0 A resp. U =
0 V), unless it has been stopped manually
before.
3.9.12 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 different from manual operation. The external documentation “Programming Guide ModBus & SCPI”
explains the approach. In general the following apply:
• The function generator is not controllable via the analog interface
• The function generator is unavailable if R mode (resistance) is activated
