Peak Programme Meter
The Peak Programme Meter (PPM) shows the peak level for each input channel. In one eyesight it shows the signal levels.
As the name suggests, the meter responds to the peak signal values. It can be used to help set the signal generator level or gain knobs in the system. Ideally the signal is as strong as possible, without overloading the input. A typical target level is -10 dBFS.
Features
For each channel there is a vertical bar. The bar is updated each time the DAQ sends a block of data and is green under normal circumstances. If clipping is detected, the bar turns red. To make it easier to read the peak levels, a horizontal line holds the peak value.
Options
Right-click inside the PPM to open an options menu. It has two settings:
- Minimum visible level: Sets the vertical range.
- Decay rate: Sets how quickly the bars drop, after the peak has passed. It does not affect the horizontal line that holds the peak value.
