Technical field
The utility model relates to a kind of calibration equipment, especially relates to a kind of ultrahigh frequency office and puts state-detection instrument calibration equipment.
Background technology
Testing tool is put in ultrahigh frequency office can be divided into generally that tester is put in hand-held ultrahigh frequency office, tester is put in portable ultrahigh frequency office and test macro is put in centimetre-sized location ultrahigh frequency office.Hand-held ultrahigh frequency office puts tester and generally has 1～2 ultra-high frequency signal treatment channel, adopts the embedded type CPU chip, and instrument generally all has time domain collection of illustrative plates or other relevant collection of illustrative plates to show the ultra-high frequency signal amplitude of test.Tester is put in portable ultrahigh frequency office, refers to be with 2～4 uhf channels, adopts notebook computer control front end signal conditioning and data collector, and data are analyzed and testing apparatus is put in the office that diagnoses.Office of ultrahigh frequency office puts the state-detection instrument and generally is made up of sensor, signal regulating device and digital storage oscilloscope, and collection office discharge signal carries out acquisition process, finishes type analysis and the discharge level assessment of innings discharge signal.Therefore whether this detecting instrument accurately directly influences the precision that detects, and therefore needs a kind of device that can carry out verification to the parameter of detecting instrument, guarantees accuracy.
The utility model content
The purpose of this utility model is exactly to provide a kind of ultrahigh frequency office to put state-detection instrument calibration equipment in order to overcome the defective that above-mentioned prior art exists.
The purpose of this utility model can be achieved through the following technical solutions:
State-detection instrument calibration equipment is put in a kind of ultrahigh frequency office, the signal gathering unit that the state-detection instrument is put in pulse signal generator, verification host computer system and ultrahigh frequency office is put in this calibration equipment office of comprising, described office puts pulse signal generator and is connected with signal gathering unit, and described signal gathering unit is connected with described verification host computer system.
Described office puts to be connected with between pulse signal generator and the signal gathering unit and puts pulse signal be used to playing a game and carry out the circuit for signal conditioning that secondary is regulated.
Described signal gathering unit is connected by concentric cable with the verification host computer system.
Compared with prior art, the utility model is put the signal gathering unit that pulse signal generator simulation local discharge signal is input to detecting instrument by office, and the signal of its collection is shown by the verification host computer system, judge whether consistent with parameter calibration, can carry out verification to the signal gathering unit of detecting instrument separately, reduce the complexity of verification, and improve the accuracy of verification; Can play a game simultaneously and put pulse signal and carry out secondary and regulate, increase scopes such as the amplitude of its output and frequency, check the applicability of calibration equipment.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
As shown in Figure 1, state-detection instrument calibration equipment is put in a kind of ultrahigh frequency office, the signal gathering unit 3 that the state-detection instrument is put in pulse signal generator 1, verification host computer system 2 and ultrahigh frequency office is put in this calibration equipment office of comprising, office puts pulse signal generator 1 and can carry out the circuit for signal conditioning 4 that secondary regulates by one and be connected with signal gathering unit 3, and signal gathering unit 3 and verification host computer system 2 are connected by concentric cable.
The utility model is put pulse signal generator simulation local discharge signal by office, be input to the signal gathering unit of detecting instrument, and the signal of its collection is shown by the verification host computer system, judge whether consistent with parameter calibration, can carry out verification to the signal gathering unit of detecting instrument separately, reduce the difficulty of verification, and improve the accuracy of verification; Can play a game simultaneously and put pulse signal and carry out secondary and regulate, increase scopes such as the amplitude of its output and frequency, check the applicability of calibration equipment.
