Long Time Recording
The CoCo is a full features signal analyzer but it can also be used like a data logger and record long time streams.
The Coco can record long time records to memory while monitoring real-time spectra.
The Rec../Stop button is used to start and stop recording long time records.
The CoCo-80 combines two traditional instruments, a data recorder and a signal analyzer into one hardware platform. Due to the requirement of different use cases, the user interface design is a bit unconventional. Two hard buttons, Rec./Stop and Save are designed for storage; two soft buttons, Restart and Run/Hold are designed for controlling the data processing flow.
The Rec./Stop Button is used to control the streaming of time stream data to memory. After a CSA project is selected, pressing the Rec./Stop button will start the display and also start recording the time stream to memory. The red flashing Rec icon at the top of the screen indicates that the data is recording.
To stop the recording press the Rec./Stop button again. The red flashing Rec icon will not be displayed indicating that the recording has stopped.
Before a time stream can be recorded it must be defined in the Parameter Settings/Time Steam Recording Setup. If no time streams are defined in this setting when the Rec./Stop button in pressed then a message will indicate that no signal are selected.
The Rec./Stop button can also be pressed after the Run button is pressed. The Run button starts the display of live signals but does not start recording. After a recording is stopped the display will continue to display live signals until the Hold button is pressed.
The figure below illustrates the difference between the concepts of Display - Run/Hold, Time Stream - Record/Stop and Signal - Save. The Display mode is independent of the Record or Save functions. When you change the Display mode between Run and Hold it has no effect on the Save or Record functions. That means that time streams can continue to be recorded when the display is in Hold mode.
