[0032] The core of the utility model is to provide a pulse supply device and a signal driving device thereof. The electrical parameter modulation module adjusts the voltage value of the pulse signal to a specified value, and / or adjusts the current value of the pulse signal to the required current value of the chip to be tested, thereby obtaining a pulse signal suitable for the chip to be tested, and finally outputs it to the chip to be tested through the signal output module. Pulse signals with different electrical parameters can be obtained through a single pulse supply device, which reduces the number of pulse supply devices used and saves costs.

[0033] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] Please refer to Figure 1 , Figure 1 A schematic diagram of the structure of a signal driving device provided by the utility model, the signal driving device comprises:

[0035] A signal receiving module 1 is connected to the pulse supply device and is used to receive and transmit the pulse signal output by the pulse supply device;

[0036] The electrical parameter modulation module 2 is connected to the signal receiving module and is used to adjust the voltage value of the pulse signal to a specified value and / or adjust the current value of the pulse signal to the required current value of the chip to be tested;

[0037] The signal output module 3 is connected to the electrical parameter modulation module 2 and the chip to be tested, respectively, and is used to transmit the pulse signal regulated by the electrical parameter modulation module 2 to the chip to be tested;

[0038] The required current value is within the adjustable current value range of the electrical parameter modulation module 2 .

[0039] Specifically, taking into account the technical problems in the above background technology, and considering that the electrical parameters of the pulse signal can be changed by modulation, the pulse signal output by the pulse supply device is modulated in the embodiment of the utility model, and then transmitted to the chip to be tested, so as to achieve the adjustability of the pulse signal. Finally, a variety of pulse signals can be obtained based on a single pulse supply device, so as to match with various types of chips to be tested and reduce equipment costs.

[0040] Specifically, if one wants to modulate the pulse signal output by the pulse supply device, then one must first lead out the pulse signal output by the supply device. Therefore, in the embodiment of the utility model, the pulse signal output by the pulse supply device is received and transmitted by the signal receiving module 1, and the transmission destination is the electrical parameter modulation module 2, which is the core module for performing signal modulation in the embodiment of the utility model. The electrical parameter modulation module 2 can adjust the voltage value of the pulse signal to a specified value, and / or adjust the current value of the pulse signal to the required current value of the chip to be tested (that is, the electrical parameter modulation module 2 in the embodiment of the utility model can adjust one of the current and voltage separately, or can adjust the current and voltage at the same time). Finally, the signal output module 3 transmits the pulse signal adjusted by the electrical parameter modulation module 2 to the chip to be tested, so as to carry out the pulse signal test.

[0041] The specified value may be flexibly set, for example, it may be set to a required voltage value of the chip to be tested, and the embodiment of the present utility model does not limit this.

[0042] Specifically, when the electrical parameter modulation module 2 "adjusts the current value of the pulse signal to the required current value of the chip to be tested", the current modulation target of the electrical parameter modulation module 2 can be manually set to the required current value of the chip to be tested, or it can be an adaptive modulation of the electrical parameter modulation module 2, that is, the electrical parameter modulation module 2 can automatically modulate the current value of the pulse signal within its own adjustable current value range and output the required current value of the chip to be tested. The embodiments of the present utility model are not limited here.

[0043] Among them, it is worth mentioning that through the use of the signal driving device in the embodiment of the utility model, the pulse signal provided by a single pulse supply device can meet the needs of various types of chips to be tested, thereby reducing the number of pulse supply devices used and saving costs.

[0044] The utility model provides a signal driving device. Considering that the electrical parameters of a pulse signal can be changed by modulation, the utility model first receives the pulse signal output by a pulse supply device through a signal receiving module, and then uses an electrical parameter modulation module to adjust the voltage value of the pulse signal to a specified value, and / or adjusts the current value of the pulse signal to the required current value of a chip to be tested, thereby obtaining a pulse signal suitable for the chip to be tested, and finally outputs it to the chip to be tested through a signal output module. Pulse signals with different electrical parameters can be obtained through a single pulse supply device, thereby reducing the number of pulse supply devices used and saving costs.

[0045] Based on the above embodiments:

[0046] As an optional embodiment, the signal driving device further includes:

[0051] Among them, the multi-channel pulse interface in the male connector is connected to the multi-channel pulse interface in the female connector in a one-to-one correspondence.

[0052] Specifically, considering that the pulse signal is usually output by the female connector of the pulse supply device, and the female connector may include multiple pulse interfaces, in order to successfully obtain the required pulse signal from the female connector, the signal receiving module 1 in the embodiment of the utility model first includes a male connector with multiple pulse interfaces, and the multiple pulse interfaces in the male connector are connected one-to-one with the multiple pulse interfaces in the female connector, so that the link basis of the pulse signal is available. However, a single pulse signal is usually required when performing a pulse signal test on the chip to be tested. In order to obtain the required pulse signal from the multiple pulse interfaces, in the embodiment of the utility model, a channel selection module is used to select a pulse interface in the male connector to be connected to the electrical parameter modulation module 2, so that the electrical parameter modulation module 2 can modulate the pulse signal in the pulse interface.

[0068] Of course, in addition to the pulse supply device, the power supply can also be of other types, which is not limited in the embodiments of the present invention.
