AT-600系列精密步進衰減器設計用于在DC-1 MHz范圍內提供極其精確的衰減。精選的精密芯片電阻和表面貼裝結構提供了精確性、長壽命和可重復性。裝置配有旋鈕，并針對標稱衰減步長進行校準。
Model No. | Frequency Range | Attenuation | Attenuation Accuracy | |
Range (dB) | Steps (dB) | |||
AT-600- | DC-1 MHz | 0-50 | 1 | 0-10dB steps ±.2dB 20-50dB steps ±.5dB |
AT-601- | DC-1 MHz | 0-90 | 10 | |
AT-602- | DC-1 MHz | 0-100 | 1 | |
Impedance: 600 ohms 5% Input Voltage: 10 VRMS maximum Connectors Type: BNC Female or Binding posts | Rotation: Attenuation increases in CCW direction with stops at each extreme Detent: 30° |
To designate the attenuator desired use:
1: 600 for a 2 section, 0-50dB attenuation in 1dB steps 601 for a 2 section, 0-90dB attenuation in 10dB steps 602 for a 3 section, 0-100dB attenuation in 1dB steps | 2: B for BNC female connectors P for binding posts |
Example: AT-602-B is a 0-100dB attenuator with BNC female connectors
