Brief description of the drawings
Fig. 1 is topological diagram of the present utility model.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples, and embodiment of the present utility model includes
But it is not limited to the following example.
Embodiment
As shown in figure 1, the antenna measurement device of volume production WiFi/ blue tooth productses, including host computer 1, it is connected with host computer
Radio frequency power meter 2, the radio frequency switch 3 being connected with radio frequency power meter, and multiple tests being connected with radio frequency switch
End, wherein, the radio frequency switch is also connected with host computer to receive control signal, and the test lead includes and radio frequency switch
The RF antennas 4 of connection, and for disposing WiFi/ blue tooth productses 7 to be measured and being allowed to the installation position 5 that is coupled with RF antennas, institute
Installation position is stated provided with interface 6, WiFi/ blue tooth productses to be measured is connected by the interface with the host computer.Preferably, institute
RF antennas, radio frequency switch, radio frequency power meter and host computer is stated to connect using coaxial cable each other.Preferably, on described
Position machine connects the interface on the installation position by USB connecting lines or netting twine.
Based on such test device structure design, we improve existing method of testing, and the present embodiment is to set 5 surveys
Try exemplified by end, can install Devices to test DUT 5 installation positions for the first time, be switched to by PC control radio frequency switch
First RF antennas connection, and first DUT transmission signal is controlled, signal is received by radio frequency power meter, then by actually connecing
The receiving power contrast of the receiving power and theoretical calculation that receive, can determine that whether DUT is qualified, complete first DUT test；Its
In, because transmission power could be arranged to fixed value, then theoretical receiving power=（The antenna of transmission power * DUT antenna efficiencies-two it
Between attenuation of air value）* RF antenna efficiencies, if actual receiving power is less than the receiving power of theoretical calculation, can determine that
The DUT is defective products, and it has a quality problems or the problem of antenna does not have in welding.
Then control radio frequency switch is switched to the connection of next RF antennas, i.e., second RF antennas connection, then controls the
Two DUT transmission signals, signal is received by radio frequency power meter, finally judges whether second DUT be qualified；At the same time, that is, exist
Previous DUT is completed after test, the Devices to test DUT more renewed, and by the DUT sorting placements tested.By such mode according to
Installation And Test that is secondary and circulating 5 test end positions, so as to effectively reduce the integrated testability time.
On the calculating of testing time, 1. due to that need not be opened and closed shielded box, changing DUT time can save in 5s,
The utility model is calculated with 5s, and 2. DUT starts time 35s for the set time, and 3. the time of radio frequency switch switching antenna is 2s
Left and right, the time of DUT transmission signals is 1s, and it is 1s or so to receive signal and the time to specific power, that is to say, that use this reality
DUT testing time can be tapered in 5s with the test device of new design, this sentences 5s calculating.It follows that test the
One DUT time is 45s, and five DUT of first test install startup simultaneously, is testing second to the 5th DUT
When only respectively need 5s testing time, therefore have used time 65s, one DUT used times 13s of average test altogether in first five DUT.When
When testing the 6th DUT, changed and be installed and activated after first DUT completes test due to it, only need 20s etc. to be launched
Time, its install start needed for the 40s times in have 20s be test other 4 DUT, opened so as to save a large amount of waits
The dynamic time, therefore be that the 6th to the tenth DUT test has the used time altogether for 45s in five DUT of second batch, average used time 9s.
Theoretically, the DUT tests average used time of subsequent batches is 9s, it is contemplated that some problems in practice, the average used time
It is positively retained at 75s in 10s or so, corresponding existing test mode to test for a DUT, the detection time greatly shortened,
It is especially suitable for the antenna detection of this volume production WiFi/ blue tooth productses.
Furthermore, test lead number can also be changed to reach the shorter test used time, for example, when test lead number is 8
And at more than 8, the DUT that previous installation position can be completed when testing other DUT successively changes installation and started（The time
For 40s, the single DUT testing times are 5s）, so as to realize the process of continuous loop test, each DUT average used time equivalent to
Its testing time 5s, drastically increases testing efficiency.And it is also simply corresponding to increase the hardware cost that test lead number brings
RF antenna amounts and corresponding coaxial cable and USB connecting lines（Or netting twine）, cost is very cheap.
And on the other hand, theoretically, can also simultaneously be surveyed using many test equipments in existing testing scheme
The mode of examination, contrasts above-described embodiment, it is assumed that using the testing scheme of prior art, while test five DUT, then its average survey
The examination time is 15s, but required hardware configuration is test a DUT configuration 5 times, that is, needs 10 host computers, 5 nothings
The connection cables of gauze card, 5 shielded boxes and respective amount, its hardware cost is significantly larger than the utility model.Again even so,
Assuming that existing, price is more cheap can to connect the host computer of multiple wireless network cards, then the quantity of host computer can be optimized for 2
Platform, but its hardware cost is also far above the utility model.Due to wireless network card and the connection mode and DUT and host computer of host computer
Connection mode it is identical, therefore wireless network card and Devices to test DUT can not be connected simultaneously on same host computer, if connecting by force
Connect, can be clashed when it transmits data, it is impossible to test.
Above-described embodiment is only preferred embodiment of the present utility model, not to the limitation of the utility model protection domain,
In every case design principle of the present utility model, and the change for carrying out non-creativeness work on this basis and making are used, all should
Belong within protection domain of the present utility model.
