Keysight N6700 User’s Guide
Front Panel:
SCPI Command:
Select Output\Mode.
Select either Voltage priority or
Current priority and press Select.
To set output 1 to current priority:
FUNC CURR,(@1)
NOTE
When switching between Voltage priority and Current priority, the
output is turned off and the output settings revert to their Power-on or
RST values. Refer to Appendix E for information about voltage and
current priority mode operation.
Set the Slew Rate
Front Panel:
SCPI Command:
Select Output\Advanced\Slew
Then select Voltage or Current
Enter the voltage or current
slew rate in the Slew Rate field.
Check Max slew rate to
program the fastest slew rate.
To set the voltage slew rate to 5 V/s
VOLT:SLEW 5,(@1)
To set the current slew rate to 1 A/s
CURR:SLEW 1,(@1)
To set the fastest slew rate:
VOLT:SLEW MAX,(@1)
The voltage slew rate determines the rate at which the
voltage changes to
a new programmed setting.
When set to MAXimum, INFinity, or to a very
large value, the slew rate will be limited by the analog performance of
the output circuit. The slowest or minimum slew rate is model-
dependent and is a function of the full scale range. For other ranges the
minimum slew rate is proportional to the full scale range.
The current slew rate control is only available on Keysight Models
N678xA SMU. It determines the rate at which the current
changes to a
new programmed setting.
When set to MAXimum, INFinity, or to a very
large value, the slew rate will be limited by the analog performance of
the output circuit. The slowest or minimum slew rate is model-
dependent and is a function of the full scale range. For other ranges the
minimum slew rate is proportional to the full scale range.
Enable the Output
Front Panel:
SCPI Command:
Press the On/Off key.
To enable/disable ALL outputs
using the On/Off key, select
System\Preferences\Keys.
Check On/Off affects all channels.
To enable only output 1:
OUTP ON,(@1)
To enable outputs 1-4:
OUTP ON,(@1:4)
Because of internal circuit start-up procedures and any installed relay
options, output on may take between 35 and 50 milliseconds to
complete its function. Conversely, output off may take between 20 and
25 milliseconds to complete its function.
To mitigate these built-in delays, you can program the output to zero
volts rather than using the output on/off function.
