Analyser
Inputs
Two channel balanced or unbalanced analogue (22kohm) and balanced (24 bit) AES3/EBU or (16 bit) SPDIF provided on a 25-way D-type connector.
Level Measurement
Two channel simultaneous bar graph and decimal readouts, -100dBu to +18dBu. Accuracy ±0.01dB @ 0dBu, with reduced accuracy at lower levels (±0.13dB @ -50dBu).
Option 1: Fast Quasi-Peak
Option 2: Super-fast Quasi-Peak
Option 3: RMS
Frequency Measurement
10Hz-20kHz left channel frequency measurement, digital readout, accurate to ±1Hz
Phase Measurement
±180º, 10Hz-20kHz with ±1º accuracy.
PPM (Peak Programme Meter)
Simultaneous two-channel display with PPM dynamics.
Option 1: IEC268 type 11 (BBC standard).
Option 2: Fast attack PPM (x10 attack time)
Option 3: Dual speed PPM (option 1 and option 2 displayed for left channel).
Noise Measurement
Residual Noise -66dBu (468-weighted) with analogue connections, -100dBu (468-wtd) with AES/EBU connections.
Option 1: 468 Quasi-Peak (fast decay)
Option 2: 468 Quasi-Peak (slow decay)
Option 3: Unweighted Quasi-Peak (22Hz-22kHz)
Option 4: Unweighted RMS (22Hz-22kHz)
Option 5: A-weighted Quasi-Peak
Option 6: A-weighted RMS
Distortion Measurement
Choice of Lindos-preferred Distortion Residue (468-wtd 1kHz), or traditional THD measurement.
Initially measures the incoming frequency and finds the nearest Lindos frequency (from 10Hz – 10kHz), then nulls the fundamental and measures distortion. Noise floor -66dBu (468-wtd) with analogue connections. Range -100dBu to +18dBu with digital connections.
Option 1: Distortion Residue 468-wtd Quasi-Peak @1kHz
Option 2: THD+N RMS (22Hz-22kHz)
Crosstalk Measurement
Measures weighted crosstalk, automatically muting the channel selected, while driving the other at the selected frequency and level.
Option 1: 468-wtd Quasi-Peak
Option 2: Unweighted Quasi-Peak (22Hz-22kHz)
Option 3: Unweighted RMS (22Hz-22kHz)
FFT mode
Two channel, real-time spectrum analysis of incoming signal in any mode. 10Hz-20kHz display, linear or log scale, windowing and averaging options.
Oscilloscope View
Two channel, real-time oscilloscope display with auto-trigger.
Sequence Mode
Available when controlled with Lin4WinXP (free), allows fully automated measurements of noise, distortion, phase and crosstalk to be made, and plots of frequency response, phase response, distortion response, noise against time and level against level. Results are displayed graphically for saving, printing, tolerance testing and on-line publishing.
