What parameters does the mobile phone test test?

The main parameters for testing the mobile phone are:

1) transmit power level tx power level (5 ~ 19).

2) frequency error frequency FER.

3) Phase error.

4) RF spectrum.

5) Switching spectrum.

6) Acceptance sensitivity RX sensitivity.

7) modulation spectrum.

Main equipment required for testing the system:

1) analog base station comprehensive tester? For example, the CMU200 of Germany's Rod Schwartz Company.

2) Special power supply for communication, such as 2304A dual-channel mobile communication high-speed power supply, will be displayed when the pulse load changes.

It shows remarkable voltage stability and can measure load current. To test wireless communication devices that require battery power (e.g.

Such as a portable telephone, which is optimal for experiencing actual load changes in a very short time interval.

3) Mobile phone fixtures, etc.

4) Test and develop software? Labview such as labview or VB is fast and convenient.
