When discussing measurement technology and signal processing, sampling rate 、 bandwidth Data throughput is very important. In the previous article, we introduced the sampling rate. Today, we focus on data throughput.

What are data throughput and net throughput?

In addition to sampling rate and bandwidth, data throughput and net throughput are also important parameters. They represent the amount of data that can be transmitted over wired or wireless media at a time. Therefore, they are a good way to measure the overall performance of the system. These two parameters are usually in bits per second.

But what is the difference between throughput and net throughput? The two parameters are similar but not identical. Data throughput refers to the total amount of data transmitted per time unit, so it is also called total throughput. The net throughput only refers to the transmission of useful data (payload) per unit time. This means that the net throughput excludes data header, data tail, correction data, control data, and other data required for control transmission.

When it is necessary to transmit all data to the motherboard and hard disk drive at a high sampling rate, these two parameters are crucial factors. Especially for large measurement systems with multiple devices, data throughput needs to be concerned.

Note: In addition to the above terms, the term "data rate" is also used conventionally. Although technically, this is not accurate, because "data rate" is a broad term, which may involve several concepts in data transmission. However, since the term "net throughput" is not very common in spoken language, we also use the term "data rate" or "gapless storage rate" to replace net throughput.

summary

When choosing the perfect measurement settings for your application, you have to deal with a large number of characteristic parameters. The three key parameters are:

Sample Rate - Average number of samples of waveforms obtained per second

Bandwidth - interval width in the spectrum

Data rate - amount of data transferred per time
