9. Enter the amplifier gain (fix:1000), and the designated sampling frequency. For field potential
recordings in slices, a sampling frequency of 10 or 20 kHz is ideal.
10. Add a data display to you virtual rack by clicking the data display icon, or by selecting it from
the "Edit" menu. The data display will open with the layout selected in the Data Source Setup.

12. You may have to adjust the position and span of the axes until you can clearly see the noise level.
You should see the baseline with a maximum noise level of +/- 8 μV. Be aware that the USB-ME32-
STIM4 has a wide filter bandwidth (0.5 Hz to 3 kHz). Therefore, it is likely that you will pick up low
frequency noise. To avoid this, use a virtual 10 Hz High Pass filter (see MC_Rack manual for
details).
