Actually, that Wiki had this to say about the Ultra:?
Absolute maximum input level of +6dBm with 0dB internal attenuation
Absolute maximum short term peak input power of +20dBm with 30dB internal attenuation
Suggested maximum input power of +0dBm with internal attenuation in automatic mode
For best measurements keep input power below -25dBm
So it would seem that -3dbm and zero internal attenuation won't harm anything, but also won't give the best measurement.? ?I might set it up that way just to compare the results when I have more than 40db of attenuation available.?
