Full duplex 1 kHz Distortion and Noise, 96 kHz:

Measurement conditions:

• Measurement software: Mac the Scope 4X 4.28, 2048 point (X2) FFT, Square window function, linear frequency axis.
• Stimulus signal was generated by Mac the Scope / Waavebox. Signal: 1 kHz, DIGITAL LOCK enabled, 2048 sample latency (e.g., sequence length).
• Connections were made by connecting input and output with 1/8" stereo shielded TRS patch cable.
• Plot range is -160 dB to 0 dBFS.

Note: the distortion measurements may be replicated with the free, demo version of Mac the Scope (the session timeout limit provides ample time for making the measurement).

• Here are links to some other measurements.
