POWER RATING: 2 watts average to 25°C ambient
temperature, derated linearly to 0.2 watts at +100°C. 500
watts peak (5 μsec pulse width; 0.2% duty cycle).
ATTENUATOR SET (AS-20): Model 56 is also available in
a Attenuator Set which includes five different attenuators
(3, 6, 10, 20, 30 dB). Refer to Attenuator Sets data sheet
for more information.
