PCIe总线时间间隔分析仪卡

TIAs are the most powerful type of time measurement instruments. In addition to the functions provided by traditional “frequency counters”, “time interval counters” and “universal counters”, TIAs include new functions, run at a much higher rate, provide a continuous measurement capability, and report results together with their time of occurrence. These capabilities give you much more insight into the dynamic nature of your signal and much higher throughput.

This difference in capability is similar to the difference between voltmeters and oscilloscopes. Although both voltmeters and scopes measure the voltage of a signal, the scope provides much faster sampling and displays the results vs. time. For example, the voltmeter may be able to make 1000 measurements per second, which you can log with a computer. You may also log the time of occurrence of each measurement and display a plot of

Max Freq. (All Func.) - This is the maximum frequency for all measurement functions without prescaling (frequency division)

Max Freq. (Freq. Func.) - This is the maximum frequency for the frequency-type functions (1C1E) when using the prescaler for products with a prescaler (frequency division). See the datasheet for details.

Time Resolution - The single-shot time resolution of the hardware.

Freq. Resolution - The resolution for Frequency Average and Period Average functions is dependent on the single-shot time resolution and the duration of the measurement (effective gate time). It is easier to specify it as a number of digits per second. For example, 12 digits/s means that you will get 12 digits of frequency resolution with a 1 second gate time, or 9 digits in 1 millisecond. If the signal input is 1 MHz, 9 digits of resolution translates to 0.001 Hz resolution.
