RS232 - For serial communication, click the RS232 box. Select the Baud rate
and the serial port (COM1, COM2, etc) from their respective menu rings. The
baud rate must correspond to that of the DS345. Be sure that the DS345's
RS232 interface is enabled.
GPIB - If the GPIB button is pressed, the available GPIB addresses found on
the system are displayed in the menu ring. Select the GPIB address that
corresponds to the GPIB address set on the DS345.
Enable Local This selection takes the DS345 out of remote mode and enables local front
panel control.
Trigger Menu The Trigger menu allows setting the DS345's trigger generator parameters for
triggered bursts of arbitrary waveforms. When one of the trigger choices is
selected the DS345 will automatically be set to BURST modulation, the burst
count to one, and the modulation enabled. If all of the trigger choices are
deselected the DS345's modulation will be turned off (continuous waveforms).
The default setting is continuous waveforms. The six trigger choices are the
five that are internal to the DS345 plus the PC mouse. If PC mouse is selected
a trigger button will appear on the AWC screen. The DS345 will trigger each
time the button is clicked.
Zoom Menu The zoom menu allows the AWC display to zoom in and out on features of the
arbitrary waveform. This is useful when the waveform has a many points. This
menu is disabled when there is no waveform on screen.
Zoom This selection sets the AWC display to any portion of the current waveform.
There are two parameters: the starting and ending point numbers to be
displayed.
Zoom In Magnifies the center 50% of the waveform by a factor of two.
Zoom Out Zooms out from the center of the screen by a factor of two.
Pan Right Pans to the right by 50% of the screen width.
Pan Left Pans to the left by 50% of the screen width.
Full View Zooms out to display the entire waveform.
Help Menu The selections in this menu provide some useful information about AWC.
AWC Help Selecting this menu item brings up a window with general information about
the AWC program and about each of the menu items, as well as some
troubleshooting tips.
SRS/AWC Info Displays the current version of AWC and general information about SRS.
Notes Provides information about the numerical coding of the trigger source line of
the data file format.
