RIGOL was founded in Beijing in 1998 and released its first product, a high-performance virtual digital storage oscilloscope, in May 1999. [1]In 2018 the company released the new RSA5000 real-time spectrum analyzer and the MSO7000, as well as MSO5000 series, based on the new ASIC based Ultravision-II platform.
The X-Y mode also lets the oscilloscope serve as a vector monitor to display images or user interfaces. Many early games, such as Tennis for Two, used an oscilloscope as an output device. [12] Complete loss of signal in an X-Y CRT display means that the beam is stationary, striking a small spot.
A bridge-parallel amplifier topology is a hierarchical combination of the bridged and paralleled amplifier topologies, with at least four single-ended channels needed to produce one bridge-parallel channel. The two topologies complement each other in that the bridging allows for higher voltage output and the paralleling provides the current ...
A class-B push–pull amplifier is more efficient than a class-A power amplifier because each output device amplifies only half the output waveform and is cut off during the opposite half. It can be shown that the theoretical full power efficiency (AC power in load compared to DC power consumed) of a push–pull stage is approximately 78.5%.
There are a number of RF amplifier tubes that operate in a similar fashion to the TWT, known collectively as velocity-modulated tubes. The best known example is the klystron . All of these tubes use the same basic "bunching" of electrons to provide the amplification process, and differ largely in what process causes the velocity modulation to ...

To minimize these effects, transimpedance amplifiers are usually designed with field-effect transistor (FET) input op-amps that have very low input offset voltages. [3] An inverting TIA can also be used with the photodiode operating in the photoconductive mode, as shown in figure 2. A positive voltage at the cathode of the photodiode applies a ...
The operational transconductance amplifier (OTA) is an amplifier that outputs a current proportional to its input voltage. Thus, it is a voltage controlled current source (VCCS). Three types of OTAs are single-input single-output, differential-input single-output, and differential-input differential-output (a.k.a. fully differential), [ 1 ...
