1121 Audio Analyzer

The Model 1121 audio analyzer provides fast, accurate measurements including frequency, AC or DC level, distortion, SINAD and signal-to-noise ratio. It also includes an audio source providing accurate low distortion signals over wide frequencies and level ranges.

• Frequency range from 10 Hz to 200 kHz
• Low-distortion audio source for testing systems, amplifiers, receivers and components
• Measures AC/DC level, distortion, SINAD, S/N, frequency
• Ten readings per second
• 50-, 150- and 600-ohm output impedances
• 300 µV full-scale range sensitivity
• 70 dB Common Mode Rejection Ratio
• Sweeps frequency or level
• Non-volatile memory for instant recall of up to 99 complete front-panel setups
• IEEE-488 interface
