Few questions about AD5933 evaluation board

I am trying to measure the impedance of some biological sample.

There are some problems.

1 .Can I read impedance for low frequency?  UG 364 table. 2. says that it is possible to read impedance for low frequency by reducing the clock frequency.So should i connect an external clock to the hardware, or jest change in software?(i am taking the readings in laptop).


2.Is the board providing a constant current source? if yes, how can i get the value of the current,or how can i get the impedance using the evaluation board in constant current source?.
