Abstract
The utility model discloses an automatic testing system for a power amplifier. The automatic testing system for the power amplifier mainly consists of a signal source connected with the power amplifier to be tested, a frequency spectrograph and a general testing card; the signal source and the frequency spectrograph are connected with a control computer by a GPIB (General Purpose Interface Bus) card; and the general testing card is connected with the control computer by a serial port line. The automatic testing system has the advantages that the time cost can be reduced, and the occupied cost of the equipment and the manpower cost can be also reduced.
Description
Technical field
The utility model relates to a kind of power amplifier automatization test system.
Background technology
Power amplifier test be power amplifier in process of production, in order to guarantee that properties of product satisfy the customer requirement index, reduce the important step of defective products shipment, also be the important means that the research staff verifies properties of product simultaneously, research and development are early stage, the same mode that adopts manual test, similar to the situation of manual assessment, manual test requires the tester that instrumentation is familiar with and abundant power amplifier test experience is arranged, according to statistics, the time of each passage important indicator of each product of R﹠D cycle test is about 0.75 people/sky, and each product also will be through test repeatedly in process of production, so manual test is not suitable for production test yet.
The utility model content
The purpose of this utility model is to overcome the shortcoming and defect of above-mentioned prior art, and a kind of power amplifier automatization test system that reduces time cost, hold facility cost, human cost is provided.
The purpose of this utility model is achieved through the following technical solutions: the power amplifier automatization test system, mainly be made of the signal source that links to each other with tested power amplifier, frequency spectrograph and universal test card, described signal source, frequency spectrograph and universal test card all link to each other with control computer.
Described signal source all links to each other with tested power amplifier by the radio frequency cable with frequency spectrograph, and when control computer drive control signal source, to tested power amplifier transmitting radio frequency signal, frequency spectrograph obtains the output power of tested power amplifier to signal source by the radio frequency cable by the radio frequency cable.
Link to each other with power lead by control line between described universal test card and the tested power amplifier.
For in test process for the universal test card provides power supply, guarantee its operate as normal, the utility model also comprises the power supply that links to each other with the universal test card, links to each other by power cable between described universal test card and the power supply.
Described signal source, frequency spectrograph link to each other with control computer by the GPIB card; Being connected with test card links to each other with control computer by Serial Port Line.
Described control computer is equipped with the N16 Auto-Test System.
In sum, the beneficial effects of the utility model are:
(1) reduce time cost: after introducing Auto-Test System, the automatic test duration of each each passage of product was controlled in 10 minutes, had shortened the cycle of production, had improved our competitiveness of product;
(2) reduce the hold facility cost: because the shortening of test duration, a set of equipment can be at identical time test more products, thereby have reduced our hold facility cost;
(3) reduce human cost: except the test duration is gone up saving, also reduce difficulty of test simultaneously, common operator also can be tested normally, saved human cost greatly.
