NOTHING MORE THAN THAT (excluding DC voltage - for which a simple DMM is good )

regards
i have 2 osciloscope.... analog 20mhz and digitl 100mhz

but with analog 20 Mhz its ok...

we can make a good measurement with 20mhz...

@vishalv,

What you are looking for is an infra red rework station (this is what you mean by laser as there are no laser systems, only infra red and they don't use hot air). A good one would be Jovy Re-7500. www.jovy-sys.com or a cheaper substitute (but with far less features) would be tornado infra. You can watch the videos on the Jovy site. If your budget were to permit it, i'd recommend you buy the RE-7500.

Best regards!

all testers are good but without COMPLEATE SEVICE SOFTWARE LIKE PHOENIX YOU CANT DO NOTHING WITH RF SECTION
becous when you want to BIAS RF PA IN 32dBm or you wan to CALIBRATE RX IQ
how do it without SERVICE SOFTWARE

FOR NOKIA -PHOENIX ,PKD1 ,FPS8,SMARTCARD, CALIBRATED JIG.......
FOR MOTROLLA-- RADIOCOM
FOR SAMSUNG-- DONT KNOW
FOR SE --

IF YOU HAVE ABOVE ALL COMPLEATED SET YOUR TERSTERS ARE OK OTHERWICE GOOD FOR SHOW
