FAQ


What is record length?



A. Two misunderstanding on oscilloscope field:


1. Focus on sample rate, miss the record length

When selecting oscilloscope, people used to focus mainly on sample rate. Many of them tangle if the sample rate is 4G or 5G. However, the sample rate depends on record length from time to time. If your oscilloscope only gets 2.5K record length, the sample rate would never reach 4G even it supports.

2. The nominal sample rate VS the real-time sample rate

Almost every oscilloscope manufacturer chooses to print the sample rate (like “4GSa/s”) on PVC label and stick on oscilloscope. However, the nominal sample rate is the highest sample rate one machine can reach, not the real-time sample rate. The oscilloscope only keeps on the highest sample rate for a little while. Some oscilloscopes even eliminate the real-time sample rate display, which misleads the engineers to believe that the sample rate holds still all the time.

 

B. Parameter Explanation

Oscilloscope First Formula: Record Length= Sample Rate × Waveform Time

Similar with Battery Formula: Battery Volume= Consumption Rate × Working Time

The battery volume is fixed, to extend the working time, consumption rate should lower down.

The same truth that the sample rate must lower down while extending the waveform time.

Conclusion: for waveform observation, if the bandwidth is fit, the core parameter is the real-time sample rate. Real-time sample rate depends on record length. Let’s see the real-time sample rate and time scale under different record length.

 

Time Scale

Sample Rate under 512M record length

Sample Rate under 10M record length

Sample Rate under 2M record length

5ms/div

4G Sa/s

200M Sa/s

40M Sa/s

50ms/div

500M Sa/s

20M Sa/s

4M Sa/s

500ms/div

50M Sa/s

2M Sa/s

400K Sa/s

 

We can tell from the chart, the sample rate drops down when waveform time rise up.

 

C. The Core Value of Large Record Length

1. Malfunction Detect

Every oscilloscopes can easily trigger strong character error signals. But what frequency does it appear? Does it regularly show? It couldn’t tell without the help of large record length.

2. Data gathering

Large record length means more original data captured. The measurement sample points would be more. In measurement, waveform based on 512M points and 1M points are highly different.
