cmu vs agilent

To develop and test GSM cell phone in laboratory and factory, which wireless communication tester is better, R&S' CMU200 or Agilent's 8960,or other instruments, why?

I have used only the CMU-200 so I can only speak about that. If you want to do engineering test the CMU-200 will do fine. If you have the right options it will allow a full base station emulation. It will give TX power , Out of band Power , Spread , RX sensitivity and has a good built in spectrum analyzer. If you want to do production tests the CMD-55, CMD-80 is a better choice. It allows scripting and programming to run the test in auto mode so no user intervention is required and has the ability to do a Pass Fail setup in the script. But R & H is top notch stuff.

It depends on your application.In a auto-test system,agilent8960 is a preference,because it has more fast operation speed than CMU200 with GPIB control.But the CMU200's user interface is more friendly,so it's a better choice for hand-use.Also, the price is different,agilent8960 is more expensive. Only for your reference.

That's right , it really depends on your application .If you are RF designer , I advise you to use CMD200.

R&S CMU200 is much better,easy to operate,friendly interface,etc

If You are expected to test UMTS in the future, the 8960 has much more capabilities (in the road map too).

I found some situation in 8960 is pass, but CMU200 fails.
their sampling and average algorithm are not the same, both of them are good.
