To leave the relays closed when output 1 is turned off:
OUTP OFF,NOR,(@1)
To leave the relays open when output 1 is turned on:
If you have Option 760 installed, you can also reverse the polarity of the
output and sense terminals. Note that this command briefly turns the
output off while the output and sense terminal polarities are switched.
Also note that if this option is installed in Model N6742B, the maximum
output current will be limited to 10A.
Select
.
Then check the Reverse box.
Uncheck the Reverse box to
return the polarity to normal.
To switch the output and sense
terminal polarities of output 1:
OUTP:REL:POL REV,(@1)
To return the polarities back to
normal:
When the output polarity has been reversed, the voltage meter on the
front panel display will show a bar over the voltage reading:
Set the Output Resistance
This information applies to Keysight Models N6781A and N6785A only.
Output resistance programming is primarily used in battery testing
applications, and only applies in Voltage priority mode. Values are
programmed in Ohms, from – 40 mΩ to + 1 Ω.
Select
Output\Advanced\Resistance
.
Enter a value and press Select.
To set the output resistance to 0.5 Ω:
OUTP:RES 0.5,(@1)
This information applies to Keysight Models N678xA SMU only.
Keysight Models N678xA SMU have several voltage bandwidth modes to
allow you to optimize output response time with capacitive loads.
The Low bandwidth setting provides stability with a wide range of output
capacitors. Additional bandwidth modes provide faster output response
when the output capacitance is restricted to smaller values.
