hi,
Unless the grounds are connected the circuit won't work since the current has to flow back to the source. If your purpose of isolating ground is to avoid noise you may use ferrite beads(having attenutation at that frequency) to connect both grounds.
what you told first is right. you have to resonate it at the desired frequency or near to that. then to match it for the desired bandwidth you can use lumped element or distributed element matching.
HI,
If RS485 module is nothing but a TTL/CMOS to RS485 convertor then the microcontroller side will be O.K. And for the PC side just put an RS485 to RS232 converter and connect it to the PC's RS232 port. Your job is done.
since it is showing the constellation and output EVM I assume you are using the LTE module in Agilent VSA. In that case the sampling will be set according to the standard which they may not be giving. But i thing while exporting the sampling rate may be mentioned somewhere in the file. You may...
Hi,
Eventhough the absolute value is not 0 or 180 degrees, the difference is 171-(-8) ~=179. THis observation has been made by me also in Agilent PNA network analyzer. May be it is difficult to design an absolute broadband short or open. That's why this difference may be comin.g
Hi,
If the spectrum analyzer has noise figure measurement personality then you will definitely need the source 5dB or 15dB. I have not seen any spectrum analyzer with noise source inbuilt.
Hi,
Kindly set the sampling rate that you need in Agilent studio as well as the VSA. That's the only way out. Once captured if you want to change then the data doesn't make any sense
Hi,
It depends on who is going to drive the speaker. ideally the speaker impedance should match with the amplifier output impedance for maximum power transfer. Just search for maximum power transfer theorem to understand this concept. But i don't understand why you need series resistance...
Hi,
All RF devices in the market are manufactured to work for 50 ohms load impedance for some particular reasons. But some semiconductor devices made for multi purposes will not be able to give you 50ohms impedance at the output. So they say it has to be matched. Matching means converting a...
