Audio Precision ATS-1 - Page 13

Measurements may be displayed in a wide variety of units, including
the following:
.
volts
.
dBm (with a user-specified impedance reference)
.
dBu
.
dBV
.
dBr (dB relative to a stored measured value)
.
dBg (dB relative to the present generator output amplitude)
.
watts (with a user-specified impedance reference)
.
FFS (Fraction of Full Scale, for digital measurements)
.
dBFS (dB below Full Scale, for digital measurements)
.
Hz/kHz
.
% or dB for relative measurements
The chosen units are remembered for each measurement function, so
when you return to that function the units will be automatically
displayed.
Several band-limiting and noise-weighting filters are provided. In the
analog domain, the following are available:
.
Standard 22 Hz-22 kHz audio bandpass
.
30 kHz and 80 kHz lowpass
.
400 Hz highpass
.
Tunable 1/3 octave bandpass
.
A-weighting (IEC-A)
.
CCIR weighting
.
Sockets for two optional filters, selectable from a wide variety
In the digital domain, the following filters are available:
.
22 Hz and 400 Hz highpass
.
15 kHz, 20 kHz, 22 kHz, and Sample Rate/2 lowpass
.
A-weighting (ANSI/IEC-A)
.
CCIR weighting (two types)
.
Tunable 1/13 octave bandpass
