SCPI commands — voltage source
A) [:LEVel] [:IMMediate] [:AMPLitude] <NRf>
Use this command to set the voltage source output level from -505V to 505V. Note that if
the STATe is on, then the voltage will change as soon as this command is processed. Send-
ing a value outside of the present range will generate Error -222 “Parameter Out of
Range”. To go to a higher value, you must first change the source range.
B) RANGe <NRf>
This command selects the range: 10V, 50V, or 500V. If you choose a range lower than the
present level, the level will be changed to the maximum value for that range. The range
selected will be the one that best accommodates the value sent. A value of 10.01, for
example, will select the 50V range.
C) ILIMit <NRf>
Use this command to set the voltage source current limit to 25
μ
A, 250
μ
A, 2.5mA, or
25mA. Note, however, that the maximum current limit for the 50V and 500V ranges is
2.5mA.
