| 1 | Leakage current can be determined from path to ground or from path to path. | |
| 2 | In parallel with the ideal switch is the contact leakage resistance and capacitance. | |
| 3 | Each row is also coupled to each column through the relay contact leakage resistance and capacitance. | |
| 4 | Isolation is a measure of the leakage resistance between paths on the switch card. | |
| 5 | Guarding is the only practical way to achieve high channel-to-channel isolation and low leakage currents. |
