hi iam using st tx 01 ask trnsmitter in my project .iam giving data with bit rate 1kbs bt iam unable to receive it.how can i know whether transmitter working correctly?
Hook up an oscilloscope and look at the output waveform on antennae. Now give a high or low input and watch the output change. Also try providing a known signal.
u said that ,see the output of antenna in CRO right,bt st-tx01 antenna has power delivering max capacity is 10dbm so if i apply 5 v0lts as input i will get 5mv at the out put,i am unble to reconige it in cro.another problem is our cro max freq is 10mhz ,bt output of antena around 430 mhz so what i can do nw to verify the trnsmtter
you said that ,observe output of antenna in CRO right,but st-tx01 antenna has power delivering maximum capacity is 10dbm so if i apply 5 v0lts as input i will get 5mv at the out put,i am unable to recognized it in cro.another problem is our cro max freq is MHz ,but output of antena around 430 mhz so what i can do now to verify the transmitted wave
Still missing important details about the receiver side.
What are you using to receive the signal? What is the antenna length? What is the distance between transmitter and receiver ?
Can you attach photos of the circuits?
thanks for reply.iam using st-rx-02 ask receiver.iam using wire antenna with length 10cm .distance between the tansmitter and receiver is around 30 cm.
