Oscilloscope with high power and low error

Abstract

The invention discloses an oscilloscope with high power and low error, and the oscilloscope with high power and low error comprises an attenuator, a pre-amplifier, a sampling apparatus, an analog-digital converter, a storage, a sampling clock, a time-base circuit, a crystal oscillator, a central processing unit (CPU), a display and an antenna module; the attenuator, the pre-amplifier, the sampling apparatus, the analog-digital converter, the storage, the central processing unit (CPU) and the display are connected orderly; the analog-digital converter is connected to the sampling clock, the time-base circuit is connected to the sampling clock, the crystal oscillator and the central processing unit (CPU) respectively; the central processing unit (CPU) is further connected to the antenna module; the Low error oscilloscope of the improved amplifier structure has strong operational capability and processing function by adopting the CPU, not only is the performance of the oscilloscope strengthened, but a plurality of interfaces capable of being expanded are increased, the circuit of the sampling part is divided into multiple modules, as sampling clock, time-base circuit and crystal oscillator, the error of the internal circuit can be reduced by detailing the function and the internal setting is more human.

Description

technical field [0001] The invention discloses a high-power and low-error oscilloscope, which belongs to the field of signal processing equipment. Background technique [0002] As a time-domain electronic measuring instrument, oscilloscopes are widely used in the field of measurement.
