Agilent/Keysight 33502A

The Agilent/Keysight 33502A is a dual-channel isolated amplifier that extends the output capabilities of function and arbitrary waveform generators. It delivers up to 50 Vpp (±25 V) with 200 mA output current and greater than 20 V/µs slew rate, enabling high-power signal delivery to demanding test loads. Each channel floats ±42 Vpk to earth, eliminating ground loop constraints while maintaining channel-to-channel isolation exceeding 75 dB at 5x gain.
