IRIS-Net
Supervision & Test
The Supervision & Test Dialog integrates functions for testing and monitoring power amplifiers.
You can check control input states and trigger control outputs. A testing generator that provides sine, pink noise and
white noise signal output allows acoustical testing. Status indicators for general power amp operation, the two
amplifier channels and the load connected, indicate whether everything is okay or where failures occurred. You have
the option to choose, which errors are combined and indicated in a general fault message.
A click on the Supervision & Test tab selects the page while in the Setup & Control Window.

20 Hz 20 Hz...20 SWEEP START sets the start frequency of the sine-sweep signal for
kHz speaker impedance testing.
20 kHz 20 Hz...20 SWEEP STOP sets the stop frequency of the sine-sweep signal for
kHz speaker impedance testing.
Clicking the START TEST soft-key launches the speaker impedance
test. The generated sine-sweep signal sweeps over the previously
defined frequency range. The graph of the measured impedance
values is indicated in the Loadplot display. Clicking this soft-key again
cancels the test at any time.
10% 5%...50% Clicking the SET REF. CH. A and/or SET REF. CH. B soft-key saves the
last test as reference. Clicking the CLEAR REF. CH. A and/or CLEAR
REF. CH. B soft-key clears the corresponding reference. TOLERANCE
defines the allowable deviation of the impedance graph. Actual
measured test results and saved tolerance ranges are being compared
during system check. A fault message is displayed if any point of the
actual measurement falls outside of this tolerance range. The
tolerance range is graphically displayed as spread in the
corresponding color that surrounds the reference graph.
Clicking the CLEAR. CH. soft-key clears the current loadplot. Clicking
the EXPORT REF. CH. soft-key stores the current loadplot to a file.
Clicking the IMPORT REF. CH. soft-key loades a stored loadplot from a
file.
