Receiver Test Apparatus and Method
Systems and methods using the systems of testing radio frequency receivers include a radio frequency receiver testing device that has a PIN switch adapted to receive a radio transmission, a thermal diode coupled to the PIN switch and controlling the amount of noise within the PIN switch, and a noise diode providing a stable noise source to the radio frequency receiver testing device.
TRACKING EXTRA-VEHICULAR TECHNICIAN PROGRESS IN A NETWORK MONITORING SYSTEM
A technician's progress may be tracked using a location data from a mobile device being carried by the technician. For instance, when the technician undocks a test instrument, such as a handheld meter for measuring leakage signal, the mobile device may be triggered to track and transmit its locations. Therefore, the test instrument-mobile device combination may continuously generate two pieces of information-leakage signal measurement from the test instrument and the location from the mobile device. Both the test instrument and the mobile device may transmit the corresponding pieces of information to a remote server, which may associate the leakage signal measurements and locations. The present system may have a visibility of the location of the technician and the corresponding leakage signal measurement when the technician is outside the vehicle, compared to the conventional systems that are generally blind in these situations.
