Signal Delay in Ribbon Cable measurements
Experimental Set Up
| setup without Ribbon Cable | setup with Ribbon Cable |
 |
|
Measurements
| 2 pulses without Ribbon Cable | 2 pulses with Ribbon Cable |
 |
|
We have about 170 ns delay of signal in Ribbon Cable for 100 ns pulse. For other pulse width the delay is about the same.
