The CPU status LED
The CPU board contains the CPU chip.
The CPU status LED is the left hand LED on the top right corner and allows the operator to monitor the CPU. If
this LED blinks (like a heart beat) the CPU is working properly.
Virtual Analyzers Data Processing
Many analyzers take multiple readings step by step. This means that when the user wants to get for example
acceleration overall, velocity overall, velocity time signal and velocity spectrum from one sensor, then the
analyzers take the overall first, then the second overall with the integration, after that the time signal and finally
the spectrum. The time which is required for all 4 readings is the sum of all 4 individual times.
The VA3Pro instrument includes high speed chips and it uses a much more advanced concept. There is one
virtual analyzer created in the instrument memory for every individual reading. All virtual analyzers read the data
from the input DSP board and perform the required data acquisition at the same time.
What does this mean? It means that the total required time is not equal to the sum of all individual times, but it is
equal to the time required for the longest reading.
