Capture controls for standard mode are dependent on the selected CMTS device. Some controls may not be configurable depending on CMTS vendor support.
NOTE: Some fields retain their values from
previous captures.
Capture controls for standard mode can include:
Start and end frequencies
- Start Frequency
- Starting frequency of the capture.
- End Frequency
- Ending frequency of the capture.
NOTE: Start and end frequencies are not available for Casa CMTS devices.
- Samples
- This is the number of samples in the capture. Starting frequency and ending
frequency, along with the number of samples determine the resolution per
point.NOTE:
Captures may have a variable resolution based on the sample count chosen (determined by the vendor device).
- Domain
- The value for Domain is set to Frequency, indicating that amplitude is
measured versus frequency (MHz).
This mode supports Frequency Domain Analysis.
- Capture Interval
- The number of seconds between samples. Value range is 0-10 seconds.
- Service Identifier
- The Service Identifier menu lets you select either IdleFFT or Any options for the capture.
