Description:

LA102 Audio Measuring Set
10kΩ and 600Ω selectable. Differential inputs, with L/R selection.
Level measurement
-95 to +28dBu in 10dB ranges (autoranging/manual).
RMS 2Hz-100kHz -3dB, 20Hz-40kHz -0.2dB.
High pass filter
400Hz with12dB/octave selectable.
Level accuracy
±0.05dB +28 to -60dBu, ±0.2dB -60 to -80dBu
Frequency
Reciprocal counting 20Hz-20kHz, 4-5 digit readout
Phase
±180º, 20Hz to 20kHz with ±2º accuracy (up to 40kHz with reduced resolution).
Noise measurement
-105 to +8dBu in 10dB ranges.
Options 2,3,6,7
ITU-R 468 unweighted, RMS 22-22k, ITU-R 468/ARM, ITU-R 468 RMS.
Residual Noise
-97dBu ITU-R 468468 wtd, -107dBu RMS 22kHz.
Rumble measurement
Crosstalk
-117 to +8dBu, narrow band measurement, automatic freq. selection. Measured with a two stage 12dB/oct bandpass filter. -1dB at 20% frequency error, -10dB at one octave.
Options1-6
100Hz, 315Hz, 1kHz, 6.3kHz, 10kHz, 40Hz. 400Hz instead of 315Hz available to order.
Options 7-9
80Hz-400Hz, 1.8kHz-21kHz and 12-21kHz bandpass.
Residual Noise
-117dBu at 1kHz, -111dBu at 6.3kHz typical.
Distortion
THD+Noise, relative, with automatic fundamental measurement and filter frequency selection. Measured with a combined multi-stage notch and high-pass filter. Frequency tolerance is ±1% for 70dB rejection. No nulling required and the broad notch rejects flutter sidebands effectively. (-60dB @ +2%)
Options 1-6
100Hz, 315Hz (3rd harmonic), 1kHz, 6.3kHz, 10kHz, 40Hz.
Input Level Range
-60dBu to +28dBu, noise limits readings below 0dBu.
Wow & flutter
-80dB to -20dB (0.01% to 10%).
Default
weighted quasi-peak to IEC386, DIN45507.
Options 2,6,7
Unweighted quasi-peak, weighted RMS, Unweighted RMS.
Quantising distortion
40Hz notch, 400Hz HP, Wtd ITU-R 468 & Unwtd rms.
Difference frequency dist.
70Hz bandpass filter for 2nd order difference frequency distortion measurement on double tone with 70Hz separation (1kHz-20kHz).
FIM (Frequency Intermod.)
Responds automatically to all LA101 sequences.
FSK speed tolerance
±4% speed error allowed.
Monitor loudspeaker
With volume setting and listen switch.
Scope/headphones output
Sweeps produce a graph on the display with cursor readout, automatic scrolling and scaling facilities. Sequences produce a graph plus several pages of data with quick access.
Sequence results can be printed directly on an Epson ESC/P, IBM or HP Deskjet compatible printer fitted with serial interface. Printout includes high resolution frequency response graphs.
5 sequence memories allow later printout or analysis.
5 user programmable tolerances in addition to 10 pre-programmed tolerances (Selftest, IBA, EPS81, EPS84, EPS98, Studer A812 etc)
Test tape mode
LA102 can automatically measure frequency response, W&F and speed from a test tape, ignoring voice announcements and plotting an interpolated graph between the spot frequencies it finds.
