Hi,
I am looking for help on what specification of oscilloscope is needed for gsm repair, Nokia recommend a dual channel 100mhz oscilloscope but they are soooo costly.
Is a dual channel oscilloscope of 20mhz any use or what is the minimum spec needed.

Thanks in advance
Max

From NOKIA recommand oscilliscope , you can try to search at EBAY, for Hitachi oscilloscope. 400Mhz less then 500 USD !

Probe so important too!

Hi,
Gsm analyser is toooooooo expensive. Plz if you havn't a good sgm cservice enter d'ont lost your time and mony. But you can buy an oscilloscope with HF probe at 2GHz and d'ont forget that you can use a normal oscilloscope at 500 Mhz if you want repair commun phone failing, mainly power supply...
Good luck
