XADC output voltage with frequency changing

Hi everyone,

  Am wroking in Zynq board. I have noticed some voltage loss at my xadc output, as my input to the xadc is 1V from signal generator. Why am not getting a exact 1V at the output of XADC, if am increasing my frequency of Signal generator, the xadc output voltage is reducing further. Is it anyone have idea on this.

XADC wizzrd Specifications:

 * Unipolar/ Bipolar mode

* Single channel mode

* Vp and Vn as input channel

* No calibration and avaeraging is enabled.

 I will attach a word documnet where the XADC input and voltage is tabulated for variousn frequencies of arbitary waveform generator.
