N701xA Series Active Termination Adapters
技术资料
- 30/40/59 GHz Single-ended active termination adapters
- Low attenuation settings for high SNR, low noise measurements
- Ability to terminate signal to a 50 Ω non-ground voltage (Vterm)
To date, most oscilloscopes with 50 Ω inputs terminate to ground by definition. However, a particular communication system often requires the 50 Ω termination to a voltage rather than to ground. The Keysight N701xA-Series single-ended active termination adapters feature a user-adjustable common termination voltage (Vterm) and extremely low noise performance. The termination voltage between –4.0 to +4.0 V can be controlled internally by the oscilloscope. Two oscilloscope channels and two adapters are needed for making a differential measurement, which allows the A-to-GND, B-to-GND and differential (AB) signals to be viewed in real time. Utilizing low attenuation ratio settings, the adapters enable an extremely low noise floor, especially at high-sensitivity vertical scales (< 400 mV) when compared to Keysight InfiniiMax III probing solutions.
