The memory trace can be used for mathematical operations with the data trace. The mathematical operations are performed on complex values before they are formatted for display. The result of math operation replaces the data trace. The following mathematical operations can be performed:
Divides the measured data by the memory data. The trace status field indicates: D/M. |
|
Data* Memory |
Multiplies the measured data by the memory data. The trace status field indicates: D*M. |
Data– Memory |
Subtracts a memory data from the measured data. The trace status field indicates: D–M. |
Data+ Memory |
Adds the measured data to the memory data. The trace status field indicates: D+M. |
Normalization |
Pressing the Normalization softkey performs 3 steps in sequence: 1. Saves the current data into memory. 2. Turns on the math operation Data/ Memory (normalizes the measured data). 3. Turns on "data only" display type. The trace status field indicates: D/M Dat. |
|
To access math operations, use the following softkeys: Display > Memory > Data Math > [ Data / Mem | Data * Mem | Data – Mem | Data + Mem | OFF ] |
|
Normalization function can be done using the following softkeys: •for one trace: Display > Memory > Normalize •for all traces of the active channel: Display > Memory > Normalize All |
note |
If the memory FIFO function is turned on, check if the active memory trace is the desired trace for math operation (See Memory FIFO). |
