The Keysight (Agilent) 230B is a wideband RF power amplifier engineered to boost output power from conventional signal generators across the 10 MHz to 500 MHz band. It delivers up to 4.5 W into 50 Ω loads and 15 V across external 50 Ω terminations, making it suitable for test and measurement applications demanding amplified RF signals at moderate power levels.
