Connection
Analog outputs (channels 23–24)
CAUTION
Analog output current limit: 5mA (maximum).
The Model 7706 contains two DAC (Digital to Analog Converters). Use these analog outputs for tasks such as applying a voltage
bias to DUTs or analog control. The two analog outputs of the Model 7706 are capable of providing voltages in the range of
±12V. The analog outputs can be set from the front panel or over the bus.
Figure 15
shows a simplified schematic of the analog
outputs.

Analog output
In the following examples, the Model 7706 module is in slot one of the Model 2700.
Sample 1: Set analog output 1 (channel 23) to 10.0V
To set analog output 1 using the front panel: under the SHIFT->CARD menu, key in the decimal value (for this example, 10.0)
for the menu item “AOUT1: +XX.XX”, and press enter. To set Channel 23 (analog output 1) over the bus, send the following
command:
OUTP:VOLT 10.0,(@123)
NOTES
Refer to “Front panel operation” for more information on menus and key location.
Voltage may be set in 1mV steps (values are rounded to the nearest millivolt).
