^Note: the sampling rate is also limited by the RZ processor used for stimulator
control. When sampling at 195.3125 kHz, recording is limited to the first five
channels on each bank of channels.
Slew Rate for the IZ2H‐16
The slew rate is a measure of how quickly the output voltage of the device can
change. The plots below show the effect of the slew rate on a square wave
produced by the IZ2H at different loads and levels.
