Abstract

A measuring system for testing and measuring a wireless communication apparatus includes a plurality of first probes, a plurality of second probes, and a control module. The first probes are arranged to face toward a first side of the wireless communication apparatus for testing and measuring a plurality of first test points provided on the first side of the wireless communication apparatus. The second probes are arranged to face toward an opposite second side of the wireless communication apparatus for testing and measuring a plurality of second test points provided on the second side of the wireless communication apparatus. The first and second probes detect wireless signals of the wireless communication apparatus via the first and second test points, respectively. The control module is electrically connected to the first probes and the second probes for receiving a plurality of measuring signals transmitted from the first and the second probes.

Claims

1. A measuring system for testing and measuring a wireless communication apparatus, comprising:

a plurality of first probes being arranged to face toward a first surface of the wireless communication apparatus for testing and measuring a plurality of first test points provided on the first surface of the wireless communication apparatus;

a plurality of second probes being arranged to face toward an opposite second surface of the wireless communication apparatus for testing and measuring a plurality of second test points provided on the second surface of the wireless communication apparatus; and

a control module being electrically connected to the first probes and the second probes for receiving a plurality of measuring signals transmitted from the first and the second probes;

wherein the plural first probes and the plural second probes detect at least one wireless signal of the wireless communication apparatus via the plural first test points and the plural second test points, respectively, and wherein the at least one wireless signal includes any one of RF signals and microwave signals.

2. The measuring system as claimed in claim 1, wherein the wireless communication apparatus is a double-sided circuit board.

3. The measuring system as claimed in claim 2, wherein the plural first test points and the plural second test points include at least one of a power supply point (Vcc), a ground, a signal transmission point, and a wireless signal point.

4. The measuring system as claimed in claim 3, wherein the control module transmits a test signal to the wireless communication apparatus via one of the first probes and a signal transmission point of the first test points, so that the wireless communication apparatus enters into a test mode.

5. The measuring system as claimed in claim 3, wherein the control module transmits a test signal to the wireless communication apparatus via one of the second probes and a signal transmission point of the second test points, so that the wireless communication apparatus enters into a test mode.

6. The measuring system as claimed in claim 3, wherein the plural first probes and the plural second probes detect the wireless signals of the wireless communication apparatus via a wireless signal point of the first test points and the second test points, respectively.

7. The measuring system as claimed in claim 3, wherein the plural first probes and the plural second probes detect current signals and voltage signals of the wireless communication apparatus via a power supply point and a ground of the first test points and the second test points, respectively.

8. The measuring system as claimed in claim 1, further comprising a fixture for holding the wireless communication apparatus in the measuring system and adjusting the wireless communication apparatus in position to correspond to the plural first and second probes.

9. The measuring system as claimed in claim 1, further comprising a shielding enclosure for enclosing the first probes, the second probes, and the wireless communication apparatus therein, so as to reduce external electromagnetic interference (EMI) therewith.
