In the past, deciding between an equivalent-time sampling oscilloscope and a real-time oscilloscope was a matter of determining your bandwidth requirements. However, with today’s high-performance instruments, that distinction isn’t as clear. ...
Figure 1: 25 MHz sine wave sampled using real-time sampling Figure 1 shows a 25 MHz sine wave that was captured using a Pico handheld oscilloscope using a real-time sampling rate of 100 MS/s. Figure 2: 25 MHz sine wave sampled using equivalent-time sampling ...
The real-time oscilloscopes have the real-time sample rate high enough to prevent aliasing. A numerical example is given that compares the optical PAM4 TDECQ measurement on the equivalent-time sampling oscilloscopes and on the real-time oscilloscopes.Kan Tan...
When a DSO usesequivalent-time sampling, it can acquire any signal up to the analog bandwidth of the scope regardless of the sample rate. In this mode, the scope gathers the necessary number of samples across several triggers. The input signal must be repetitive to generate the multiple trigg...
Special attention is paid to the calibration of the time-base of an equivalent-time sampling oscilloscope. Complications arise when calibrating an equivalent-time sampling oscilloscope with a variable time-base. Nonlinearities in the time-base and its wide operating range can produce a complex ...

The oscilloscope had a 25 MHz bandwidth limiter enabled, and the measurement channel was set in DC 50 Ω mode (since the preamplifier acts like a DC blocker). The sampling rate was 312 MS/s, in our case resulting in over 4 million samples per trace. The measured traces were then ...
