we are happy to let you know we have created a kit for PTP820 bench setup. Customers can use the new kits for bench testing, system staging before a radio is installed on a tower, troubleshooting in the lab, or setup for PTP 820 for classroom training.
1. PTP 820G IDU to IDU Converter Box
Used to connect two PTP 820G IDU and stimulate a 1+0 configuration; or two for 2+0/1+1 configurations
2. PTP 820S, PTP 820C and RFU-C bench test kit
Each kit includes:
2 x Waveguide to coaxial SMA (female) adaptor
2 x 2W 20dB fixed attenuator, SMA male to SMA female up to 26 GHz
2 x 18 inches RF cable, SMA male to SMA male
For 6–13 GHz, the PTP 820 radio has a proprietary interface; the flange adaptor is required to convert the radio output port to standard flange.
Do you have any spec sheets that give a better description of the parts. What i'm looking for is the adapter to go from a FRU-C 6GHz to a N-type connector for bench test/setup.
not sure what specifically you are looking for? the RFU-C has a propretory interface, we need an adpator first convert this to standard flange, then the waveguide adpator will convert it further to a SMA connector. We don't provide N-type in this kit.
Welcome to the community, Robert! Great question. The usual paper ream doesn’t work for dual polarity, especially xpic. Common sense logic would dictate that the circular polarized output of the OMT using a waveguide adapter on each unit would do the trick, but xpic depends on the polarities being exactly 90 degrees apart, and the moment we go through a waveguide adapter, we lose that discrimination. So the best way to bench test is to use 4 waveguide adapters (2 on each 820C/850C unit), and connect vertical pol to the corresponding vertical pol, and horizontal to horizontal You can then test same frequency on both polarities that is 2+0 without xpic running. For proper xpic testing, there should be some vertical component in the horizontal pol, and some horizontal in the vertical pol, so the xpic algorithm can do its magic, so you need a complex circular waveguide system, with branching networks to separate the vertical and horizontal component, and add attenuation to each polarity component = $$$ for a proper test setup. The proper waveguide adapters are dependent on the frequency, and you should have 60 to 80 dB of attenuation on each polarity to guarantee the receive signal is stable. Hope this helps.
