With the NI-4551 in Swept Sine Analysis is a lowest frequency of 0.01Hz possible?

We are trying to find the frequency response of an actuator and want to sweep from 0.01Hz to 100Hz.
Is is possible to do it in the DSA mode?

The minimum frequency you can set for the Swept Sine in DSA mode is 0.1 Hz. This is limited by the finite size of the output buffer and the minimum update rate for the DAC. The DAC must maintain a minimum rate of 1.25kS/s for accurate results. Please see the NI-4551 User Manual for more details.
