[SOURce:]POWer:RANGe <value>, (@<chanlist>)
[SOURce:]POWer:RANGe? [MIN|MAX,] (@<chanlist>)
Sets the power range. The value that you enter must be the highest value in Watts that you expect to
source. The instrument selects the range with the best resolution for the value entered. The following
ranges are available for the N679xA load modules.
N6791A N6792A
High power range from 0.3 W to 100 W from 0.5 W to 200 W
Low power range from 0.04 W to 10 W from 0.1 W to 20 W
Parameter Typical Return
0 to maximum|MIN|MAX, *RST 100|200 100 or 200
Sets the low power range (from 0.04 W to 10 W): POW:RANG 5, (@1)
l This command is coupled with [SOURce:]POWer. This means that if a range command places an
output on a range with a lower maximum power than the present power level, an out of range
error occurs. This also occurs if a power level is programmed that is too large for the present
range. Errors can be avoided by sending both level and range commands in the same SCPI mes-
sage. When the range and level information is received as a set, no range/setting conflict occurs.
l If a programmed range change occurs while the output is enabled, the output will be temporarily
disabled while the range switch occurs. The transition from on-to-off and then from off-to-on will
also be delayed by the settings of OUTPut:DELay:FALL and OUTPut:DELay:RISE.
l The query returns the maximum power that can be programmed on the range that is presently set.
The power is in the form +n.nnnnnnE+nn for each channel specified. Multiple responses are sep-
arated by commas.

[SOURce:]POWer:SLEW[:POSitive][:IMMediate]? [MIN|MAX,] (@<chanlist>)
[SOURce:]POWer:SLEW:NEGative[:IMMediate] <value>, (@<chanlist>)
[SOURce:]POWer:SLEW:NEGative[:IMMediate]? [MIN|MAX,] (@<chanlist>)
Sets the input power slew rate. The slew rate is set in watts per second and affects all programmed
power changes, including those due to the output state turning on or off. The slew rate can be set to
any value between 0 and 9.9E+37. For very large values, the slew rate will be limited by the analog
performance of the input circuit. The keywords MAX or INFinity set the slew rate to maximum.
Parameter Typical Return
0 – 9.9E+37|MIN|MAX|INFinity, *RST MAX <slew rate>
Sets the input power slewrate to 10 watts per second: POW:SLEW 10, (@1)
Sets the negative input power slewrate to 10 watts per second: POW:SLEW:NEG 10, (@1)
