The invention relates to a method for testing a measurement recording device (3) that, in a first test operating mode for testing radio devices (10), is coupled, on the one hand, to a testing device (1) for testing the radio devices and, on the other hand, to a radio device. The method makes it possible to test a measurement recording device (3) for mobile telephones in a real production environment without interrupting the production process. To this end, a second test operating mode for testing the measurement recording device (3) is provided, in which the measurement recording device (3) is coupled, on the one hand, to the testing device (1) for testing the radio devices and, on the other hand, to an essentially defined terminating impedance (17), whereby the measurement recording device (3) is tested by the testing device (1) provided for testing radio devices. The invention also relates to a testing device (1) for testing radio devices and to the use thereof.
A method for testing a measurement recording device (3) which, in a first test operating mode for testing radio devices, is coupled firstly to a test device (1) for testing the radio devices and secondly to a radio device, characterized in that a second test operating mode for testing the measurement recording device (3) is provided, in which the measurement recording device (3) is coupled firstly to the test device (1) for testing the radio devices and secondly to an essentially defined terminating impedance (10), with the measurement recording device (3) being tested by the test device (1) for testing radio devices.
The method as claimed in one of the preceding claims, characterized in that the second test mode is carried out intermittently with respect to the first test mode.
The method as claimed in one of the preceding claims, characterized in that the measurement recording device (3) comprises the terminating impedance.
The method as claimed in one of the preceding claims, characterized in that the radio devices are mobile telephones (10) which are intended to be operated in at least one mobile radio network.
A test device (1) for testing radio devices, which is coupled to the radio devices via a measurement recording device (3) in a first test operating mode for testing radio devices, characterized in that the test device (1) has a second test operating mode for testing the measurement recording device (3), in which second test operating mode the measurement recording device (3) is coupled firstly to the test device (1) for testing the radio devices and secondly to an essentially defined terminating impedance, with the measurement recording device (3) being tested by the test device (1) for testing radio devices.
Use of a test device (1) for testing radio devices for testing a measurement recording device (3), which is coupled to it, by means of an impedance measurement.
