Abstract
Digitally sampled real or sampled and down-converted complex data representing an RF signal are received. One or more statistical computations are calculated for each group of N data values. The one or more statistical computations are calculated for groups of N data values until a particular number of data values (K) are acquired. The one or more statistical computations calculated for each group are computed and stored at the time of acquisition and are available for immediate viewing on a display.
Claims19
A method for displaying signal envelope information for an RF signal, the method comprising:
- acquiring a group of N data values, wherein each data value represents one or more values of the RF signal;
- calculating one or more statistical values for the group, each statistical value being related to the signal envelope information;
- and
- repeatedly acquiring a group of N data values and calculating one or more statistical values for the group until K data values have been acquired, wherein K represents the total number of acquired data values and N is less than K;
- and
- outputting at least one of the statistical values.
A method for displaying a signal envelope information for an RF signal, the method comprising:
- a) acquiring a plurality of data values, wherein each data value represents one or more values of the RF signal;
- b) incrementing a count when each data value is acquired;
- c) determining whether the count equals a value N, wherein N represents a number of data values to be included in a group;
- d) calculating one or more statistical values for the group when the count equals the value N, each statistical value being related to the signal envelope information;
- e) resetting the count to zero when the count equals N;
- and
- f) repeating a) through e) until K data values have been acquired, wherein K represents the total number of acquired data values and N is less than K and outputting at least one of the computed values.
A system for computing signal envelope information for an RF signal, the system comprising:
- a first storage for storing a value N representing a number of data values to be in a group, wherein each data value represents one or more values of the RF signal;
- a counter for counting each input data value;
- a computational unit for receiving the data values and when an output of the counter equals N calculating one or more statistical values for a group of N data values, each statistical value being related to the signal envelope information;
- and
- a display that displays the statistical values.
