The Keysight M9484C has a maximum frequency of 54 gigahertz, extendable to 110 gigahertz with the V3080A frequency extender. The instrument achieves a phase noise of negative 148 decibels relative to the carrier per hertz at a 1 gigahertz carrier and 20 kilohertz offset. Maximum output power at 20 gigahertz is plus 22 decibel-milliwatts. Frequency switching time is 3.0 milliseconds. Maximum internal RF bandwidth is 2.5 gigahertz, extendable to 5 gigahertz with channel bonding.[1]
