Analysis of the use of RS232 Programming Cable
This article is about the usage analysis of RS232 Programming Cable.
Existing digital signal processing devices (DSP) have been widely used in signal processing in intermediate frequency, baseband or terminal parts, which has brought the technical performance of radio equipment and RS232 Programming Cable to a new and modern level, but its RF front end is still narrowband.
For software radio and RS232 Programming Cable, the A/D converter in its RF front end must be able to handle the entire communication frequency band, generally from 2MHz to 3GHz.
In addition, the typical characteristics of mobile communication signals are fading and shielding, and there may also be strong blocking and interference. As a result, the dynamic range of RS232 Programming Cable's mobile communication signal at the receiving RF end is as high as 100dB or more. If mobile communication signals of different standards are considered, the dynamic range will be even larger.
Through the above introduction and analysis of RS232 Programming Cable, hope it helps you.
