14.6  Analog Output Configuration

14.6.1 Identifying the 

Output Type

A DAC Output channel is available with one of two types of digital-to-analog
(DAC) outputs: voltage or current.  You can determine which type of output a
channel has by one of three ways:

•

Consulting the instrument’s Customer Information Sheet

•

Examining the 

SYSTEM MENU

 -> 

CONFIGURATION

 -> 

CHANNEL

 nn 

TYPE

 menu item where 

nn is the number of the channel. If the channel’s type is 

VOLTAGE DAC

, it has a 

voltage output. If the channel’s type is 

CURRENT DAC

, it has a current output.

•

Examining the channel’s circuit board as shown in the figure below.

14.6.2 Channel Menu Items

The Analog Output can be driven by any channel’s track, peak or valley value. 

See the “Channel Menu” section earlier in this chapter for a complete listing of
SETUP menu items available on the 

DAC. SETUP

 sub-menu. 

14.6.3 Output Selection

Jumpers located on the channel’s circuit board determine what outputs are gener-
ated when the value selected to drive the Analog Output (from the 

DAC. CHANNEL

 and

DAC. SOURCE

 menu items) equals the 

DAC. FULL SCALE

 and 

DAC. ZERO SCALE

 settings.
