|---|
| BLE Server |
| Server IP Address | Defines the IP address of PC running Empatica BLE Server | | String | |
| Server Port | Defines the port number of Empatica BLE Server | | Int32 | |
| Device ID | Defines the hardware device connected via Empatica BLE Server | | String | |
| Signal Generator |
| Signal Source | Defines a source for the signal. The emulated rhythmes can be used for offline validation of the chosen analysis settings | | enEmul.. | |
| Emulated Sampling Rate | Defines the emulation sampling rate (samples per second), when data is generated or streamed from a file. | | Double | |
| Primary Frequency | Defines the frequency of the primary rhythm in the generated signal, in Hz. Assign the zero to exclude the primary frequency from the generated signal. | | Double | |
| Secondary Frequency | Defines the frequency of the secondary rhythm in the generated signal, in Hz. The secondary frequency magnitude is a half of the primary frequency magnitude. Assign the zero to exclude the secondary frequency from the generated signal. | | Double | |
| Noise Level | Defines the noise level (in % to the norm magnitude of the primary frequency). The noise is added to the generated signal. Assign the zero the exclude the noise from the generated signal. | | Double | |
| External Datafile | Opens the dialog for selecting a data file containing a stream of double numbers representing a signal. If a file name without a path is defined, the data file will be picked up in the location of the experiment file. | | String | |
| Channel Configuration |
| Selected Channels | Defines what signal channels are selected for acquisition within EventIDE. Selected channels are registered in the EventIDE signal pool at runtime and become available for the signal analysis elements. | | IList | |
| Selected Channel Count | Indicates how many signal channels are currently selected for acquisition | | Int32 | |
| Total Channel Count | Indicates how many signal channels are available for acquisition in the total | | Int32 | |
| Buffer Size | Defines the size (in samples) of a circular buffer that stores incoming signal data. | | Int32 | |
| Runtime Control |
| Reset Signals Now | Runtime commands that resets the signal buffers and data acquisition | | Boolean | |
| Control |
| Is Enabled | If set to false the element is completely omitted when the experiment is run | | Boolean | |
| Title | Title of the element | | String | |

Empatica E4 Signal Element allows reading and buffering online data of the Empatica sensors, e.g. E4. The element requires the Empatica BLE Server running on the same/network computer.
