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.
