:LOAD
OUTPut[1]:LOAD <load> indicates whether the actual load applied to the
Agilent E1445A’s “Output 50/75Ω” is either matched to the output impedance
specified by
OUTPut[1]:IMPedance or is an open circuit. The output voltage into an
open circuit is twice that into a matched load. Setting
OUTPut[1]:LOAD INFinity
compensates for this effect so that the [SOURce:]LIST[1][:SEGMent]:VOLTage and
[SOURce:]VOLTage[:LEVel][:IMMediate][:AMPLitude] and OFFSet commands will
output the specified voltages into an open circuit.

Ohms
MINimum selects 50 Ω load impedance; MAXimum selects 75 Ω. Use 9.9E+37 or INFinity
to indicate an open circuit output.
Comments • The <load> value specified by this command either must be the same as that specified
by
OUTPut[1]:IMPedance or must be 9.9E+37 or INFinity, or Error -221,"Settings
conflict" will be generated.
• With OUTPut[1]:LOAD:AUTO ON set, the OUTPut[1]:LOAD value is coupled to
(tracks) the
OUTPut[1]:IMPedance value. Changing the IMPedance changes the
LOAD value. Specifying a value for LOAD sets AUTO OFF.
• Executable when Initiated: Yes
• Coupling Group: Voltage
• Related Commands: OUTPut[1]:IMPedance, OUTPut[1]:LOAD:AUTO,
[SOURce:]LIST subsystem, [SOURce:]VOLTage subsystem
• *RST Condition: OUTPut[1]:LOAD:AUTO ON is set, and the OUTPut[1]:LOAD
value is coupled to the OUTPut[1]:IMPedance value.
