Dear pawel1989,
the DCPower was not exactly designed for this purpose, i.e. using the SMU cards as function generators and/or scopes, but to set a single point or a sequence of voltages or currents. Anyhow it is possible to reach the desired V(t) or I(t) waveform by calculating and setting the appropriate signal levels for appropriately long source delay timesteps.

The first attached program allows you to use a NI 414x, NI 4135/4136/4137/4138/4139 as an FGEN. As is, the program is limited to a maximum output frequency of 5 kHz.
The second one is a standard library example with software timing for voltage sweep.
The third example is the modified version of the second, where one sine wave period is generated.
To measure back the generated signal, use the niDCPower Measure Multiple.vi:
