Step 6.
Calculate the shunt current (I=V/R) and enter the data.
Front Panel:
SCPI Command:
Enter the calculated value into the data field
and then select Next. When calibration is
complete, select Close.
CAL:DATA <data>
Low Range Current Measurement
Step 1.
Connect only the current measurement terminals of the Keysight 3458A
to the output terminals (see Cal Setup D without the resistor).
Step 2.
Select the low current measurement range. The value to program a range
must be the maximum current of the range. This example selects the
0.15 A range of output 1.
Front Panel:
SCPI Command:
From the Calibration menu, select
Current, Low Range Measurement.
Then select Start.
CAL:CURR:MEAS 0.15, (@1)
Step 3.
Select the first current calibration point.
Front Panel:
SCPI Command:
The first calibration point is automatically
selected. The ammeter should be connected.
Select Next. “Enter Measured Current” should
be displayed.
CAL:LEV P1
*OPC?
Step 4.
Measure the current with the Keysight 3458A and enter the value.
Front Panel:
SCPI Command:
Enter the value from the external DMM into
the data field and then select Next. When
calibration is complete, select Close.
CAL:DATA <data>
*OPC?
Negative Current Limit Calibration
Step 1.
Connect the Keysight 3458A, current shunt, and a power supply to the
output (see Test Setup G). Connect plus to plus, minus to minus. Set the
external power supply to 3V, 3A.
Step 2.
Select the negative-current ra
nge
. The value to select the range must be
negative and the maximum current of the range.
Front Panel:
SCPI Command:
From the Calibration menu, select
Current, Low Range Measurement.
Then select Start.
CAL:CURR:LIM:NEG -2, (@1)
