Keysight 331A Distortion Analyzer

• Distortion measurement range: 5 Hz to 600 kHz
• Distortion measurement accuracy: Distortion levels of 0.1% to 100% full scale are measured in seven ranges for frequencies of 5 Hz to 600 kHz
• Frequency calibration accuracy: Better than ±5% from 5 Hz to 300 kHz; better than ±10% from 300 kHz to 600 kHz
• Input impedance: 1 M
• Input level for distortion measurements: 0.3 Vrms for 100% set level or 0.245 V for 0 dB set level (up to 300 V may be attenuated to set level reference)
• DC isolation: Signal ground can be ±400 Vdc from external chassis
• Voltmeter range: 300 µV to 300 Vrms full scale (13 ranges) 10 dB per range
• Voltmeter accuracy: ±2%, ±5% depending on voltage range and frequency
• Voltmeter frequency range: 5 Hz to 3 MHz
• Voltmeter residual noise measurements: <25 µVrms or <30 µVrms depending on termination
• Output: 0.1 Vrms ±0.01 Vrms and 0.05 Vrms ±0.005 V into 2 k? for full scale meter deflection

Option 01 meter with VU characteristics meets FCC requirements for AM, FM, and TV broadcasting
