These detectors may alter the view of a signals appearance, depending on which is selected. Each detector can show a different picture on the same signal because of the way the detector functions. An important selection to our spectrum analyzer is the amount of digital snap shots to be taken. This will be the amount of digital snapshots that is taken in the allocated bandwidth before showing a picture. With this said, the more sampling that is put into the spectrum analyzer the slower it will seem to update, but more opportunity to capture ingress and other interference that can happen inside a cable plant. Dwell Wide- Dwell Wide takes the largest snapshot out of the amount taken, then the 7.5 MHz spectrum is peak held as the 860 DSPI tunes across the selected frequencies in 250 kHz steps. Example: In Dwell Wide, with a 32 sampling rate set, this in turn means the 860 will dwell or sit on a portion of the spectrum defined above, take 32 snap shots, and then display the picture with the max amplitude before moving on to the next portion of bandwidth. Dwell Narrow- Dwell Narrow takes the largest snapshot out of the amount taken, then a 250 kHz spectrum slice is peak held as the 860 DSPI tunes across the selected frequencies in 250 kHz steps. The difference between Dwell Narrow and Dwell Wide is that Dwell Narrow only peak holds across a 250 kHz slice, where as Dwell wide peak holds the entire 7.5 MHz. Example: In Dwell Narrow, with a 32 sampling rate set, this in turn means the 860 will go to the first 7.5 MHz of the spectrum it will look at a 250 kHz slice of the 7.5 MHz and take its 32 samples. These 32 samples will be done in a peak hold fashion, then display the sample that contains the largest signal. Averaging: This detector when selected looks at a 7.5 MHz portion of the spectrum. When it tunes to the first 7.5 MHz portion of the spectrum, it takes into account how much sampling is selected, then takes it’s digital snapshots on the entire 7.5 MHz, averages those pictures together, then shows the final averaged picture. This detector is used for looking at large amounts of bandwidth. Example: In Averaging, with a 32 sampling rate set, this in turn means the 860 will go to the first 7.5 MHz of the spectrum, take it’s 32 digital snap shots, average those together, and show the average of the 32 snapshots. 展开
