Extension of the frequency range up to 500 MHz for FRA and antenna analyzer modes
The device in the FRA and AA modes can operate on harmonics of the generator signal. To obtain a high level of harmonics in the spectrum, you can use a rectangular pulse shaper using digital logic from the LVC family. The fast slew rate of the ICs provides a high level of odd harmonics in the output signal even at high frequencies. When working with these modules, both jumpers are set to position 1-2. Please note that working at harmonics is a compromise. Using OSA-6G and 6G-VNA modules will give you significantly better results and a wider frequency range.
Operation without switching jumpers J1, J2
This module is designed to operate the device without switching jumpers. Both jumpers are permanently set to position 1-2. In the software settings, the option “Menu-> Settings-> Advanced Settings-> Jumper Free Device” is turned on. The module is used in antenna analyzer, LC meter and reflectometer modes.
