tion, the grounding connection must be made before making connections to the
instrument input or output terminals.
Starting with Version 1.02 firmware, the power-up diagnostics are normally
bypassed, and the measurement set initializes with the FFT application running.
You can start an application other than FFT by pressing and holding in the
front-panel button for the application you want to start as you turn on the front
panel power switch. The AM700 will beep twice, and you can then release the
application front-panel button. To run the power-up diagnostics, press and hold
in the front-panel Limits button as you press the front-panel power button. The
AM700 beeps twice, displays the message ‘Start mode “RUN DIAGNOSTICS”
recognized,’ and then runs the diagnostics before initialization.
Before Version 1.02 firmware, at power up the AM700 normally performs the
power-up diagnostics before initializing. To bypass these diagnostics, press and
hold the front-panel button of the application you wish to start as you press the
front-panel power button. The AM700 will beep twice and flash a message about
which start up was recognized, and then initialize without running the diagnos-
tics.
Should a power-up diagnostic fail, the measurement set should be referred to
your local Tektronix representative for servicing. You may bypass the diagnostic
routines and check to see if you can still make the measurements you require as
some diagnostic failures may not affect all the applications.
Basic Operation Information
The AM700 Audio Measurement Set is controlled by selecting from measure-
ment parameters and menus on the instrument display. A touch screen detects the
user’s selections.
Many operations are started by selecting soft keys using the touch screen
(touching the display in the right place to invoke some function) as shown in
Figure 2–2. In some menus, numerical values are entered either from the keypad
or with the control knob.
Buttons with gold outlines (Copy, Average, Cursor, Sound, Filter, Sound On,
User, and Units) have two possible behaviors, depending on how you use them.
and the application or display that is running. If an application does use a button,
no action is produced when the button is pressed.

An example is the Filter menu. Filters are only available in Audio Analyzer, so when
the Digital Interface Tester or the FFT analyzer is running, pressing the Filter button
has no effect.
