Embodiment Construction

[0035] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0036] Such as figure 1 As shown, this system is designed to provide users with a portable low-power broadband signal source in a battery-powered environment, and can provide output signals such as sine waves, square waves, triangle waves, and TTL / CMOS levels. The whole system consists of three parts: power management part M1, signal generation and processing part M2 and signal output part M3.

[0037] The power management part M1 includes a lithium battery 1, a linear voltage regulator circuit 3, a lock circuit 4, and a SEPIC circuit 2, which is the abbreviation of the single-ended primary voltage converter circuit. The lithium battery 1 is used as a power supply and is connected to the linea...

Abstract

The invention discloses a handheld low-power-consumption broadband DDS (Direct Digital Synthesizer) signal source, which comprises a signal generating and processing part, a signal output part and a power management part, wherein the signal output part is controlled by the signal generating and processing part and is used for outputting at least two different types of signals; and the power management part is used for providing power for the signal generating and processing part and the signal output part. When the signal source does not receive an input instruction signal from a keyboard beyond a preset time, the power management part is used for cutting off power supply by the signal generating and processing part. Due to the power management mode of an internal lock type circuit, the signal source can automatically enter a low-power-consumption state when the signal source is not used for a long time; the portable low-power-consumption broadband signal source under a battery power supply environment is provided for a user; a market blank can be filled; user requirements can be met; and the signal source has broad application prospect.

Description

technical field [0001] The invention relates to a hand-held low-power broadband DDS signal source, which can provide users with a portable broadband signal source and belongs to the technical field of instruments and meters. Background technique [0002] DDS is the English abbreviation of Direct Digital Synthesizer. Compared with traditional frequency synthesizers, DDS has the advantages of low cost, low power consumption, high resolution and fast conversion time. It is widely used in the field of telecommunications and electronic instruments, and is a key technology to realize the full digitalization of equipment. At present, there are many types of DDS signal source products on the market, but most of them cannot be carried around, and their use is limited when there is no power supply on site. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a hand-held low-power broadband DDS signal source that can be powered...
