We are going to use the laboratory complex of Modern wireless networks, which contains of PXI-1075e, Vector Signal Generator NI PXIe-5673E and Vector Signal Analyzer NI PXIe-5663E, for teaching students.
But there is a problem. When I want to run a lab “Measurement error of modulation GSM”, an error occurs when I press the button “measure”. It means “Attention. Wrong settings of analyzers. Enter the correct settings and repeat the measurement”. Others labs also do not want to work correctly.
Although, the setting of analyzers and of generator are correct on the instructions manual. The output of Generator and input of Analyzer are not connected by wire, but I use the antennas. Also the LED indicators Active and Access are flashing red when I’m using the device.
The result of self-test for digitizer NI 5622 is on the screen below.
Also the flashing LED indicator Red may indicate a conflict device drivers and the phase out of sync.
I did a standard test of version program and firmware. The version of the program GSM/EDGE Generator and Analyzer Toolkit are 1.1.1 and active . The firmware version of NI RFSG and NI RFSA is 2.7.
I understand that the problem is the unlocked PLL, but I am new to using the NI devices and I did not have such a big problem before. Please tell me how to solve this problem.
