The bandwidth is defined as the frequency at which the sensitivity is 0.707 of the sensitivity at DC or the lowest AC frequency (a drop of 3 dB). [13] The oscilloscope's response drops off rapidly as the input frequency rises above that point.
The first step of computing an eye pattern is normally to obtain the waveform being analyzed in a quantized form. This may be done by measuring an actual electrical system with an oscilloscope of sufficient bandwidth, or by creating synthetic data with a circuit simulator in order to evaluate the signal integrity of a proposed design.
A dual-beam oscilloscope was a type of oscilloscope once used to compare one signal with another. There were two beams produced in a special type of CRT . Unlike an ordinary "dual-trace" oscilloscope (which time-shared a single electron beam, thus losing about 50% of each signal), a dual-beam oscilloscope simultaneously produced two separate ...
The 2465 has a bandwidth of 300 MHz, the 2465A 350 MHz, the 2465B 400 MHz. The 2467 is a special case, having a micro-channel plate (MCP) CRT. This oscilloscope offers extremely high speed writing, making one-shot pulses at nanosecond duration visible in normal room light. In that aspect it was the only non-storage CRT to be able to do this.
The video bandwidth filter or VBW filter is the low-pass filter directly after the envelope detector. It's the bandwidth of the signal chain after the detector. It's the bandwidth of the signal chain after the detector.
A Tektronix TDS210 digital oscilloscope. A digital storage oscilloscope (DSO) is an oscilloscope which stores and analyses the input signal digitally rather than using analog techniques. It is now the most common type of oscilloscope in use because of the advanced trigger, storage, display and measurement features which it typically provides. [1]

DMX512 signal on an oscilloscope, annotated to show measured timing. At the data link layer, a DMX512 controller transmits asynchronous serial data at 250 kbit/s. The data format is fixed at one start bit, eight data bits (least significant first [11]), two stop bits and no parity. Each frame consists of: Break condition; Mark-After-Break
