The TA320 has two sampling modes: "time stamp mode" and "hardware histogram mode". In the time stamp mode, the TA320 records both of elapsed time and measurement result. In this mode the user can observe period variations in measurements with time by using the TIME VAR button. In the hardware histogram mode, the TA320 acquires up to 99,999,999 samples. In this mode high speed statistical computation of a great number of samples can be implemented.
This function can create a maximum of 16 windows to permit data analysis for each peak of a number of generated histograms. As an example of use, this function is extremely effective for analyzing pulse width modulated data that is employed in an optical disk.
Panorama Display Function
Example of panorama display screen |
This function indicates the particular part of a number of generated histograms that is currently displayed on the screen. It is convenient when used in combination with the multi-window. The pointer indicates the part of the overall display at the top of the screen that is displayed in the current window. (The multi-window function and the panorama display function are effective in the hardware histogram mode.) |
Examples of Measurement Functions
The TA320 has two sampling modes, the time stamp mode and the hardware histogram mode. In the time stamp mode, the measurement values and the times at which they occur are each measured, enabling the variation of the measurement results with time to be analyzed using a time variation display. In the hardware histogram mode, a maximum of 99,999,999 items of data are sampled, and statistical calculations of a large number of samples are performed at high speed, enabling histogram analysis to be performed. |

Histogram Display |
This display is effective for analyzing fluctuations of measurement values when performing jitter analysis, for example. |
List Display |
In the time stamp mode, the variation of the measurement data with time is indicated by numerical values. In the hardware histogram mode, the number of times each measurement data occurs is indicated by a numerical value. |
Time Variation Display |
This display is effective for analyzing the variation with time of the measurement data. |
Statistical Display |
This display indicates the data resulting from statistical calculations. The standard deviation is indicated as a bar graph at the bottom of the screen. |
