Apollo Waveform

Apollo Waveform provides a simple, intuitive interface to view real-time time-series waveforms from a streaming data source such as Apollo Server or field instruments.

---

Apollo Server and instruments stream data to Waveform through a User Datagram Protocol (UDP) socket, allowing Waveform to be installed on any computer with a network connection to the Apollo Server computer or to the streaming instruments.

Waveform allows you to subscribe to any time-series channel data from any streaming data source. For each subscribed channel, Waveform displays a plot with a trace plus the following computed signal statistics:

• SPS (samples per second)
• Max (maximum)
• Min (minimum)
• Avg (mean)
• RMS (root mean square)

These statistics apply to the time-series values that are currently displayed in the plot as below:

You can subscribe to an unlimited number of channels. All traces use the same time scale, but you can scale each trace individually on the vertical axis.
