We have a Reference Clock and that should go to the chip only when calibration is required.
I have a CLK_signal line which when goes
High indicates the need for reference clock for calibration
Low indicating ref clock not needed
And this clock signal line should transfer the clock to the chip...
Hi,
We have two UART peripherals in our reference board and the primary port is connected to the cellular software and so it does not log any data other than the protocol specification. SO, we log any error log or data through UART2 to the hyperterminal in the PC. Now the tests that I have been...
rs232 log with timestamp
I am receiving data from my chip to the computer through the UART communicaiton. I need to note down the timing between two transmission message. I am probing the Rx and TX lines on an oscilloscope, but i am unable to observe the transmission, whenever i send some...
can someone please guide me to some links or share their knowledge w.r.t these basics terminology in GPS.
Basically, the correlation between the clock frequency supplied and the following parameters :
GPS Week
GPS Msec
UTC Difference
Clock Time Bias:
Clock Time Uncertainty:
Clock Frequency...
hyperterminal binary
Hi,
I have logged some data from hyperterminal and an exception was thrown during the log. the exception is shown in a module with binary mode. the module can throw exception upon different reasons.so, to debug the same i need to convert this binary to a valid value. how...
What is the relation between clock frequency uncertainty and the clock frequency??
I am injecting oscillator clock frequency of 38.4 MHz with 3 ppm…and making the receiver to calibrate with the injected clock frequency and observe the clock frequency uncertainty. The frequency uncertainty...
I am new to communication field and GPS. I am involved in GPS testing.
I want to know which books/articles I can refer to understand the terminology like:
clock bias, frequency uncertainty, DOP, LNA,and terms like that. the basic functionality to get started without nay issues.
I have few books...
Hello All,
I have been asked to write
Drivers for Clock generator, Drivers for parallel port utility, Drivers for power supply for test automation purpose.
Currently all the existing actions are performed through Visual Basic based GUI to perform testing. Can I add these additional controls in...

I have a reference board (Ref1) with a functional chip that supports UART and I2C interfaces. This reference board connects thru a UART Interface to the PC which commands the functions. There is another UART interface for debug purpose. Now, I am asked to connect another reference board...
