Abstract
A test arrangement for adjusting a setup of testing a device under test (DUT) includes a main device that generates an RF signal and processes an incoming RF signal in a first frequency range; a frontend component generates an RF signal and processes an incoming RF signal in a second frequency range. The frontend component measures a signal level in a sub-range within the first frequency range; a connection cable connects the main device with the frontend component; and an analyzer predicts a behavior of the connection cable in a rest portion of the first frequency range that is different from the sub-range within the first frequency range.
Claims18
A test arrangement for adjusting a setup of testing a device under test (DUT), the test arrangement comprising:
- a main device configured to generate a RF signal and process an incoming RF signal in a first frequency range;
- a frontend component configured to generate a RF signal and process an incoming RF signal in a second frequency range such to perform a test on the DUT throughout the first and second frequency ranges, wherein the frontend component is configured to measure a signal level in a sub-range within the first frequency range;
- a connection cable for connecting the main device with the frontend component to transmit the RF signal generated by the main device in the first frequency range to the frontend component;
- and
- an analyzer integrated in or connected to the frontend component, wherein the analyzer is configured to predict a behavior of the connection cable in a rest portion of the first frequency range that is different from the sub-range within the first frequency range, based on the measured signal level of the sub-range.
A method of operating a test arrangement for adjusting a setup for testing a device under test (DUT), the method comprising:
- providing a main device configured to generate a RF signal and process an incoming RF signal in a first frequency range;
- providing a frontend component configured to generate a RF signal and process an incoming RF signal in a second frequency range such to perform a test on the DUT throughout the first and second frequency ranges;
- measuring, by the frontend component, a signal level in a sub-range within the first frequency range that is transmitted via a connection cable for connecting the main device with the frontend component;
- predicting, by an analyzer integrated in or connected to the frontend component, a behavior of the connection cable in a rest portion of the first frequency range different from the sub-range within the first frequency range, based on the measured signal level of the sub-range;
- and
- displaying, by a user interface, a prediction result of the behavior of the connection cable.
A non-transitory computer-readable recording medium, storing instructions executable by a computer processor, causing the computer processor to execute a method of operating a test arrangement for adjusting a setup of testing device under test, comprising:
- providing a main device configured to generate a RF signal and process an incoming RF signal in a first frequency range;
- providing a frontend component configured to generate a RF signal and process an incoming RF signal in a second frequency range such to perform a test on the DUT throughout the first and second frequency ranges;
- measuring, by the frontend component, a signal level in a sub-range within the first frequency range that is transmitted via a connection cable for connecting the main device with the frontend component;
- predicting, by an analyzer integrated in or connected to the frontend component, a behavior of the connection cable in a rest portion of the first frequency range different from the sub-range within the first frequency range, based on the measured signal level of the sub-range;
- and
- displaying, by a user interface, a prediction result of the behavior of the connection cable.
