When maintaining a test some parameters are common to all test types and some specific to the current test type.

All Tests

A pull down list showing the current test.The current test

Active checkboxActive - When set then Drive (V) sets the voltage at the soundboard's output.  When not set then Drive (V) sets the voltage at the associated power amplifier's output.

Fail Exit checkboxFail Exit - When set if a test fails then the sequence ends there. Time is saved because testing ends as soon as a failure occurs.  Although time is saved the abandoned tests could aid fault diagnosis.

Delay entryDelay (s)  - Can be set in the range  0.0001-1.999 seconds.  It's effect varies with test type.

Drive (V) - Sets the drive voltage to the test unit.Drive V entry

Run - When clicked executes a test with the current parameters.

Sweep and Sine Tests Only

Operator Decision - When set the pass/fail decision is made by the operator.Operator Decision checkbox

Low (Hz) - Sets the start frequency of a sweep.  It can be set in the range from 20Hz to just less than 20kHz but the higher frequency will depend on the soundboard being used.

High (Hz) - Sets the end frequency of a sweep.  It can be set in the range from just above 20Hz to 20kHz although the higher frequency will depend on the soundboard being used.

Duration (s) - Sets the duration in seconds.

Sweep and Polarity Tests Only

Re-run buttonRe-Run - Like Run when clicked executes a test with the current parameters but first clears the graphical display on the secondary test window.

Sine Tests Only

Operator Decision Yes/No optionsYes/No - Sets whether a pass is decided by the operator responding yes or no.  Only enabled if Operator Decision is set.

Sweep Type - Sets the the sweep type from No Sweep, Log/Lin, and/or Up/Down.
