### Per-signal Parameters
| Parameter | Type | Default | Applies to |
|-----------|------|---------|------------|
| `Unit` | string | `""` | Any type — informational, forwarded to client in CONFIG |
| `RangeMin` | float64 | 0.0 | float32/float64 with `QuantizedType` |
| `RangeMax` | float64 | 1.0 | float32/float64 with `QuantizedType` |
| `QuantizedType` | string | `none` | float32/float64 only |
| `TimeMode` | string | `PacketTime` | Signals with `NumberOfElements > 1` |

### Quantization Types
| Value | Wire type | Bit depth | Notes |
|-------|-----------|-----------|-------|
| `none` | same as source | — | Raw copy, no quantization |
| `uint8` | uint8 | 8-bit | Maps `[RangeMin, RangeMax]` → `[0, 255]` |
| `int8` | int8 | 8-bit | Maps `[RangeMin, RangeMax]` → `[-127, 127]` |
| `uint16` | uint16 | 16-bit | Maps `[RangeMin, RangeMax]` → `[0, 65 535]` |
| `int16` | int16 | 16-bit | Maps `[RangeMin, RangeMax]` → `[-32 767, 32 767]` |

### Time Modes
| Value | Meaning | Requirements |
|-------|---------|--------------|
| `PacketTime` | The HRT counter captured at `Synchronise()` time is used as the packet timestamp. No per-signal time metadata. | — |
| `FullArray` | `TimeSignal` carries one timestamp per element (same `NumberOfElements`). | `TimeSignal` must have the same `NumberOfElements`. |
| `FirstSample` | `TimeSignal` is a scalar giving the timestamp of element `[0]`. Elements `[1..N-1]` are inferred at `1/SamplingRate` intervals. | Scalar `TimeSignal`; `SamplingRate > 0`. |
| `LastSample` | Same as `FirstSample` but `TimeSignal` is the timestamp of element `[N-1]`. | Scalar `TimeSignal`; `SamplingRate > 0`. |
