IsoLOG 3D功能模块介绍

Q：
我需要将IsoLOG 3D测向天线的状态数据导出到外部的集成系统。
我的问题是当我们将安诺尼的IsoLOG 3D测向天线和SPECTRAN V6实时频谱仪连接时：
1、我们是否可以通过RTSA实时频谱分析仪软件的IsoLOG 3D block导出segment或者sector数据？
2、我们是否可以通过RTSA实时频谱分析仪软件的IsoLOG 3D block获悉此时与SPECTRAN V6连接的是哪个segment或者sector？

A：
The IsoLOG 3D block doesn't output that information. It is intended for controlling the antenna, not for data analysis. At most you could attempt to check the currently configured element and sector using the script block, but depending on your timing requirements that may not be accurate enough.

Alternatively you can get that information from the V6 block if the antenna RF output is connected to a Spectran V6 receiver. When connected to a HTTP server the stream will contain an "antenna" element for each sample with "azimuth" and "declination" attributes that can be used to deduct element and sector numbers (if necessary).

If you only have the antenna itself, you'll have to use its builtin HTTP interface to read its current configuration (which is what the IsoLOG RTSA block does). However you will have to account for latency yourself in that scenario, which again depending on your timing requirements might be an issue.

Q：
Could you please help me for the confusion？ What is the exactly meaning for data, "azimuth":2.3561944962,"declination":-0.78539818525", from the HTTP server stream? Is the unit " 0°－360°"? and how to understand the minus character, "-" ？

A：
Values are defined in radian, you need to multiply them with 180 / PI to get degree. Note that this already includes any offsets specified in the IsoLOG configuration.
There seems to be something wrong with the declination values though, they might be inverted. Just treat -45° as 45°.
