I am going to do a power am[lifier testing. The RF output power of the amplifier is 30dBm and my spectrum analyzer can have maximum input of 10dBm. I have 10DB attenuator. Can I go ahead with the testing? And is 10DB equal to 30 dBm?
Thanx in advance

Minimum attenuation is 20 dB. (30dBm - 20dB = 10 dBm). You need another attenuator.
dB = attenuation or gain
dBm = power
what he said!
Also, add a little more than 20 dB. If your "1 watt" amplifier starts oscillating, it might put out 2 to 3 watts instead!
