Capabilities Description
Analysis modes
Major Acquisition Modes
An acquisition may take one of the following forms:
Automatic Whenever trigger conditions are met, and the measurement can be made,
a new reading is taken.
Track Generator Sweeps Acquisition does not occur except when the internal generator is producing
a sweep.
Automatic sweep detection will be present for detecting the beginning of
sweeps. The user may indicate whether sweeps are rising or falling, and
data plotting will not commence until the appropriate sweep direction is
detected.
Measurements
Y-Axis Measurements The analyzer is capable of measuring the following and displaying them on
the Y-axis:
Received level
Stereo phase difference
THD
THD+N
IMD
Received frequency
Crosstalk + noise
Channel separation
Received level difference
In addition, a Wow and Flutter measurement is made and displayed in the
Real Time measurements only.
Sweep signals generated by the Tektronix ASG100 and ASG140 can be
used as stimulus signals for making the above measurements (except IMD,
THD, THD+N, and Wow and Flutter). These signal generators produce
‘stepped sweeps’ as opposed to continuous frequency sweeps. Frequency
content and dwell time for each step are described in the relevant user
manual for each model.
