I have a fixed ADC on PCB with 10MSamples/sec. The slope of the Signal is varying. Also the small reflections are to be measured.
Is there any other possibility to acquire the reflections data without increasing the sampling rate?
I am just putting my query in here, apologies to return the...
Hi,
I am working on TDR (Time Domain Reflectometry). I send a 7GHz bandwidth fast rising edge (14ns) square wave into a coax. I get a return Signal. I have an ADC with 10Msamples/sec. I am using MPLAB IDE for coding the microcontroller.
Now I would like to increase the Points on the...
Thank you Mr Baluncore for your advice.
Yes, it is Time Domain Reflectometry.
But I have a question regarding Transmitting Chirp down the transmitting line. In this process, the pulse is stretched. For example a 1ns pulse may be 1microsecond Long before it is upconverted and transmitted. This...
Sir,
Thank you for your Response!
Iam working the Time Domain Reflectometry.
I have a square waveform with 14ns rise time and 350ns Duration generated by a 7GHz Transistor which is controlled by a micro-controller. This is my incident pulse. The Information that I am interested in is the...
Its a square wave and I must over sample the ADC to increase the sampling rate which increases the number of sampling points. But that is not enough in my case, I guess.
Hi Stephen,
I have the raw data from the UART in real time. The set of data is in decimal counts, for example:
1;4048#gy;1;4052#gy;1;4050#gy;1;4050#gy;1;4050#gy;1;4050#gy;1;4052#gy;1;4050#gy;
and so on...
I cannot find the way to crack this!

Hi,
I am new to world of electronics and to high frequency Domain. But I am working on a design where I have a coax of 30cm length. I have used an external oscillator to generate 7GHz fast falling pulse. I am using a Controller to control the oscillator. Now I have a pulse of about 350ns...
Thank you Mr Stephen for your response.
The data I am measuring is the reflection (based on radar). At the moment I have fine reflections and like you mentioned, my next step is to interpolate to observe the reflections in time more clearly. I have this experiment running on MPLAB and I am not...
Hi
I am new member and I am new to the Signal processing so I hope I could get some help from the members to able to understand the concepts.
I have a Signal. I have a 10Msaples/sec ADC. I view the Signal on an Oscilloscope which has 20Gsamples/sec sampling rate.
The Point where I am...
