Analog Outputs (Channels 23-24) - Keithley 7706 User Manual

Analog outputs (channels 23–24)
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.

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)
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).
CAUTION
Analog output current limit: 5mA (maximum).
