5-8 Digital Output

Number of Bits

The number of bits (of resolution) per word can be set from 16 to 20 for the professional
mode. For the consumer mode the number of bits should always be set to 16.
To display the current number of bits, press [SHIFT] [# BITS]. The message "bitS" will
be displayed, followed by the current number of bits. To change the number of bits, turn
the spin knob to the left or right.

Digital Mode

The digital mode can be set to either professional or consumer modes. See the overview
at the beginning of the chapter for more information about the two different formats.
To display the current digital mode, press [SHIFT] [DIG MODE]. The message "conS"
or "ProF" (for consumer and professional modes, respectively) will be. To change the
mode, turn the spin knob to the left or right.

Inactive Functions and Parameters

The following functions are inactive for digital mode. Pressing the keys of inactive
functions will cause the unit to beep and display "not Appl" (not applicable). All modify
functions are inactive and cannot be selected.
Inactive functions are:
Offset,
Output ON/OFF,
All Modify Function (cannot be selected),
All Modify Function Parameters,
All Source Impedance's,
Trigger,
T2 Mode,
REL

Storing and Recalling Settings

Digital output settings are stored and recalled at the time as the analog output settings.
Settings can be stored in locations 1 through 9 and recalled in settings 0 through 9 with
location 0 being the default settings. Remember that the digital parameters (amplitude,
frequency) are independent of the analog parameters (i.e. different values are saved for
digital and analog output frequencies). The output mode (digital, balanced or unbalanced)
recalled will be the one the unit was in when the setting was saved.

Default Settings

Press [RCL][0] to recall the DS360's default settings. This is a good place to begin
whenever you wish to start the instrument from a known state. The default settings for the
digital output are listed below. For information on the default settings for the analog
output, refer to Chapter 3.
