I was wondering if someone can help me with a project at work. I am very very new into RF.
I work for an EMC/EMI lab and we want to do some spurious emissions testing and establish a test procedure for our clients when they have a pre-certified RF module. We want to do a wireless verification (FCC subpart 15 C) ANSI C.10
I want to make a reasonable and cheap antenna/transmitter that operates at 2.4GHz (Wi-Fi and/or Bluetooth frequencies) duty cycle of 100% or above 98%. It is to mimic a device that has spurious emissions around these frequencies. I do not know what kind of power I need to provide from my signal generator, also how do I ensure that it is continuously transmitting i.e. above 98% duty cycle. I have an idea of the specifications that I want, antenna gain , output power.
We will set our signal generator at a frequency of 2.4GHz and using our Rohde and Schwarz in spectrum analyzer mode will try to measure the spurious emissions and see the duty cycle.
If information is missing I will gladly provide some.
With some calculations I found that the length of the antenna for a half-wave is around 6.22cm and for quarter is 3.11cm. I do not know which one makes more sense.
I am trying to measure the maximum conducted output power I am looking for a device that:
- The transmitter is cable of keeping a constant transmission of data via >98% duty cycle.
- The transmitter has a decent antenna gain around from 3.2 to 4 dBi.
- The transmitter has a decent target output power from 20 to 40 dBm.
Here is an idea of what the setup will look like:
If information is missing... a question is missing \$\endgroup\$
