安诺尼实时频谱分析仪V6 Simple IQ file to Tx Demo

Q：
我一步一步按照步骤操作，并将Tx信号连接到Keysight的频谱分析仪。V6 500X连接正常，但不工作，Tx端口没有信号输出。
是什么问题呢？
A：可能是以下几个原因：
1、没有可传输IQ数据流文件；
2、输出功率太低；
3、电源（我们的USB电源或PD USB 3.1端口）未连接到POWR USB连接器；

Q：很抱歉，还是不能正常工作。我检查了一下：Transmitter Mode已经设置为“Stream”了，按理说，应该可以将IQ数据文件转化成IQ信号数据流了。能否给一个案例？

A：附件是一个200毫秒Carkey burst的IQ数据文件。信号很短，使用的时候请使用loop功能。

Q：I connect my devices instead of your attached mission and load my IQ record in the file reader, and then changing any other IQ files, you will see the SPECTRAN V6 Tx just can output the CW signal not the correlative signal from this IQ files. I had tried it again and again.which version of the RTSA-Suite Pro and FPGA version it need implement "IQ File to Tx" block function?


A:
Check the warnings (yellow Tx). Your system does not work.

BTW: You are running Rx and Tx at the same time without boost connection. This cant work.

还请注意，如果频率从一开始就不匹配，则SPECTRAN V6实时频谱分析仪的Tx输入端需要安诺尼的IQ Modulator功能模块：


另外如果需要的话，添加AARONIA安诺尼的IQ Demodulator功能模块可以减少所需的Tx带宽：

Please try attached mission with the latest RTSA (Build 10340 or higher) which now offers a Time Offset paramater within the File Read block. This should help a lot to work around low power hardware:

The mission looks like this:


File Reader:

• We are reading the IQ demo file over and over again by setting the Time Offset to a quite high 100ms and are activating the Emulate Realtime checkbox.
  
• Finally we are setting the Playback Mode to contiguous since the demo file is very short.
  

IQ Demodulator (optional, can be removed):

• We are using a small Span Frequency of 1MHz to cut the signal from the wide band and to reduce the data amount.
  
• We are reducing the Sample Rate to 10MHz so slow CPUs can handle the data amount.
  

IQ Modulator:

• We are moving the frequency from 868MHz to 2440MHz (example).
  
• We keep the Span and Sample Rate the same as in the IQ Demodulator.
  

The original 868MHz Car Key IQ Demo File is now running with 10MHz sample rate at 2440MHz and is transmitted via the SPECTRAN V6 Tx.
Use the SPECTRAN V6 Transmitter Gain slider to adjust the Tx output level.

As mentioned above make sure to add enough "buffer" via the Time Offset feature and to activate the Emulate Realtime checkbox if you use the File Reader to send IQ data to the Tx:

我们已经更新了Tx操作。
