Analyzer Overview
The Portable One Plus Access analyzer is generally configured for only
one type of measurement at a time. The type of measurement
currently being displayed is determined by the current measurement
function. Often a single measurement function will provide
measurement of several related parameters.
The Portable One Plus Access analyzer provides the following
measurement functions:
.
Level (two channels simultaneously)
.
Noise or signal-to-noise ratio (wideband, weighted, or selective)
.
THD+N (total harmonic distortion plus noise)
.
Interchannel phase and input-to-output phase shift
.
Real-time two-channel amplitude ratio (interchannel balance or
device gain/loss)
.
Real-time frequency-selective crosstalk
.
Wow and Flutter
.
SINAD (ratio of {signal + noise + distortion} to {noise +
distortion})
.
Loading (AC resistance of the input of a device connected to the
generator output)
.
AC mains check (voltage, frequency, and distortion of the AC
power line)
