2. Define Ch0 Transmitter
| Name | Description | Entry Value(s) | Status | Type | Limits | Comment | Action |
| TransmitterJitterType | Transmitter jitter type | Integer | [0, 1] |
0 = Use Ch0 IBIS-AMI jitter |
|||
| TransmitterType | Transmitter type | Integer | {0,1} |
0 = Use Ch0 IBIS-AMI |
3.0 Define Channels - the channel is linear and time invariant (LTI), but the AMI portion of IBIS-AMI models may be LTI or NLTV.
