I would like to perform following cellular test on UUT which uses sierra chip set
Tx test Modulation analysis
Carrier power test
Carrier power versus time test
Spectrum due to modulation measurement
Spectrum due to switching
RX test Static reference sensitivity level
Please let me know how can i perform the same
Which unit? Re the actual tests generically speaking the only test mode we provide for the unit is for factory testing where you can put it into a blind transmit mode on a given frequency/channel and a specific power.
Any other more complex tests would have to be run against something like an R&S CMW or which they have specific scripts/test programmes.
Airprime WP75xx is the module.
As you mentioned I have provision to put the module in transmit mode?, then how about receive mode?
Thanks these documents gave an idea of acceptance test during production.
I kindly request if you could help me understand how to perform BER test on the same module.
It stands for Bit Error Rate test
I get what BER is. What test are you intending on doing with it? You previous comment implied that you were referring to something specific if not then it is down to the test equipment to establish a link and measure it, the unit does not make provision for this sort of test.
Thanks for the response.
The main goal for us is to test GSM receiver during manufacturing using NON -SIGNALLING test equipment.(EXM 6640A)
When it comes to transmission we can put the DUT in continuous transmit mode,similarly do we have any support for receiver test.
Doing a BER test with non signalling kit is not possible because to measure BER the unit needs to be…er…signalling.
