Output n Settings
Output n tabs (Output 1, Output 2, etc) appear when any setting only applies to a particular channel. Select the appropriate tab to change the settings, which are grouped under the following categories:
- Protection Related Settings
- Mode Related Settings
- Output Related Settings
- Slew Rate Related Settings
- Measure Related Settings
Protection Related Settings
Turn off behavior | Sets the output-off status (condition which is set on the channel automatically, immediately after its output is turned off). |
Oscillation Protection (Osc) | Enables or disables output oscillation protection. Oscillation protection shuts down the output if an oscillation is detected on the output. |
Over-Power Protection (OPP) | Enables or disables over-power protection. Over-power protection will turn the output off if the input power exceeds 110% of the module's power rating. You can also specify a delay time. |
Mode Related Settings
Emulating | The Emulating dropdown list lets you access the specialized operating modes of the Keysight N678xA SMU. |
Preferred Mode Status | Set the preferred mode to either Current or Voltage. |
Output Related Settings
Current Limit Tracking | Enables or disables current limit tracking. |
Output Resistance | Enables output resistance programming and sets the output resistance level. |
Programmable Resistance |
If Programmable Resistance is enabled, the channel operates like
an electric load. Mode sets the operation mode (Fix or Emulate). For Fix mode, the channel works as a voltage source with built-in series resistor or a current source with a built-in shunt resistor. Enter the desired resistance value. |
Power Limit | Sets the power limit on output channels. |
Voltage Bandwidth | Programs the voltage bandwidth. Only applicable in Voltage priority mode. Range - Sets the compensation modes to optimize output response time with capacitive loads (the options available vary according to the model). Programming Pole Frequency/Level - Sets the low-pass filter corner frequency applied to the programming setpoint signal. |
Voltage Limit Tracking | Enables or disables voltage limit tracking. |
Under Voltage Inhibit | Enable under-voltage inhibit by selecting a Mode (Live or Latched). When enabled, the load will not sink current until the input voltage rises above the specified Voltage On setting. |
Input Short | Turn on to short the input terminals. |
Relay Polarity | Select Reverse to reverse the polarity of the output and sense terminals. |
Relay Lock Closed |
Enables or disables the locked-closed state of the output relays.
Polarity – Sets the polarity of the output relays. |
Slew Rate Related Settings
Slew Rate | Select the Max checkbox to set the slew rate to the maximum value allowed. Deselect the checkbox if you wish to enter a specific value. |
Measure Related Settings
Voltage Measurement Input | Selects the voltage measurement input (output or auxiliary voltage). |
