3 Using the Source Functions
Advanced Source Settings
Advanced button - Advanced properties are configured in the Advanced Properties window. Press the
Settings key to access the Source Settings window. Navigate to and select Advanced.
Voltage Slew - The voltage slew rate determines the rate at which the voltage changes to a new
setting. To program a voltage slew rate, enter the rate (V/s) in the Voltage Slew field. Check Maximum
to program the fastest rate. For Keysight Models N678xA SMU, the voltage slew control is only
available in Voltage priority mode. Note that the maximum slew rate is limited by the analog
performance of the output circuit. The minimum slew rate is model-dependent and is a function of the
full-scale voltage range. To query the minimum voltage slew rate, use VOLT:SLEW?
Current Slew – This is only available on Keysight Models N678xA SMU operating in Current priority
mode. The current slew rate determines the rate at which the current changes to a new setting. To
program a current slew rate, enter the rate (A/s) in the Current Slew field. Check Maximum to program
the fastest rate. Note that the maximum slew rate is limited by the analog performance of the output
circuit. The minimum slew rate is model-dependent and is a function of the full-scale current range. To
query the minimum current slew rate use CURR:SLEW?
Sense - The default sense setting is Local, where the sense terminals are connected directly to the
output terminals. If you are using remote voltage sensing as explained under 4-Wire Sense, you must
disconnect the sense terminals from the output terminals. Use the navigation keys and select the
Sense dropdown list. Selecting the 4-Wire item disconnects the sense terminals from the output
terminals. This lets you use remote voltage sensing.
Power Limit - For the majority of power analyzer configurations, full power is available from all
installed power modules. However, it is possible to configure a mainframe in which the combined
power module ratings exceed the 600 W power rating of the mainframe. The power limit field lets you
reduce the power that can be sourced from an individual output, thereby preventing the combined
power from exceeding the mainframe's power rating. To set a lower power limit, select the Power Limit
Field and enter the power limit value in Watts. Refer to Power Limit Operation for more information.
Output Voltage Bandwidth – This is only available on Keysight Models N678xA SMU. Output voltage
bandwidth settings allow you to optimize output response time with capacitive loads. Refer to Output
Bandwidth for more information.
Output Turn-Off Mode – This is only available on Keysight Models N678xA SMU operating in Voltage
priority mode. It lets you specify high impedance or low impedance mode at output on/off.
Low impedance - at turn-on the output relays are closed after which the output is programmed to the
