75 VA Convertible Low Current Source
To perform the Amplitude and Distortion check on a 75 VA Convertible
Low Current source:
1. Configure the F6000 for six Low Current sources using the Pre-set
Configurations on the F6000 Configuration display in ProTesT.
2. Set the range to 0.5 A and amplitude to 0.5 A, connect an ammeter or
appropriate shunt across the Source I1 output terminals, and turn the
source ON.
Verify that the amplitude is within the limits and that the total
harmonic distortion (THD) is <2%.
3. Change the amplitude as shown in Table F.6.
Verify that the amplitude and distortion are within the limits.
4. Repeat step 3 for the 1 A range.
5. Repeat steps 2, 3, and 4 for Source I2, I3, IR, IS, and IT.
Table F.6 lists the specifications for the 75 VA Convertible Low Current
Source measurements. Minimum and maximum amplitudes are given in
amperes. When using a 4-terminal shunt, convert the values to the
appropriate voltages.
Figure F.5 shows a typical setup for 75 VA Convertible Low Current
Source measurements.
