OUTPut
Parameters
Comments
Select 488E-6 (or MAX) for measuring resistances of less than 8000 
Ω. Select 
30E-6 (or MIN) for resistances of 8000 
Ω and above. <amplitude> may be 
specified in µA (ua).
For resistance temperature measurements ([SENSe:]FUNCtion:TEMPerature) 
the Current Source SCP must be set as follows:
 When *CAL? is executed, the current sources are calibrated on the range 
selected at that time.
When Accepted: Not while INITiated

Usage
OUTP:CURR:AMPL  488ua,(@116:123)
Set Current Source SCP at channels 16 
through 23 to 488 µA
OUTP:CURR:AMPL  30E-6,(@105)
Set Current Source SCP at channel 5 to 
30 µA
OUTPut:CURRent:AMPLitude?
OUTPut:CURRent:AMPLitude?  (@<channel>) 
returns the range setting of the 
Current Source SCP channel specified by channel.
Parameters
Comments
The <channel> parameter must specify a single channel only.
If <channel> specifies an SCP which is not a Current Source, a +3007, "Invalid 
signal conditioning plug-on" error is generated.
