Performance characteristics of the EA112 probe
| Number of channels |
8 |
| *Delay |
<35ns when 0.25 < |Ui - UT| < 2V
<40ns when 2V < |Ui - UT| < 5V
<60ns when 5V < |Ui - UT| < 10V
<120ns when 10V < |Ui - UT| < 15V |
| Threshold voltage |
-5V to +5V in <40mV steps |
| Threshold voltage setting error |
+-100mV +- 2% of the value set |
| **Max input voltage range |
+-15V |
* - Ui is the input voltage before the transition and UT is the threshold voltage
** - Stress out of the range may cause permanent damage of the device
