Voltage Ranges
The power source has two voltage ranges that are controlled by relays. The command that
controls the range is:
VOLTage:RANGe MIN | MAX | 150 | 300 | 400
When the range is set to MIN (150), the maximum rms voltage that can be programmed for
a sine wave is 150 volts rms, but it is only on this range that the maximum output current
rating is available.
The VOLTage:RANGe command is coupled with the CURRent command. This means that
the maximum current limit that can be programmed at a given time depends on the voltage
range setting in which the unit is presently operating.
Frequency
The output frequency is controlled with the FREQuency command. To set the output
frequency to 50 Hz, use:
FREQuency 50
6.2.4 Voltage and Frequency Slew Rates
Voltage Slew
The AC source has the ability to control the slew rate of AC amplitude and frequency
changes and DC amplitude. This can be used to generate ramps or to protect sensitive
loads. To set the voltage slew rate to 20 volts per second, use:
VOLTage:SLEW 20
At *RST the slew rate is set to Maximum, which means that AC voltage changes occur at the
fastest possible slew rate. The slew rate applies to programmed changes in AC/DC output
amplitude while the unit is operating in fixed mode. Amplitude changes made by the step,
pulse, and list transients are controlled by the same rules that apply to all other functions
that are subject to transient control. See section 6.4.
Frequency Slew
The AC source also has the ability to control the slew rate of frequency changes. To set the
frequency slew rate to 30 Hz per second, use:
FREQuency:SLEW 30
At *RST the slew rate is set to MAXimum, which means that frequency changes occur
instantaneously. The frequency slew rate applies to programmed changes in frequency
while the unit is operating in fixed mode. Frequency changes made by the step, pulse, and
list transients are controlled by the same rules that apply to all other functions that are
subject to transient control. See section 6.4.
