150 VA Convertible Low Current Source
To perform the Amplitude and Distortion check on a 150 VA Convertible
Low Current source:
1. Configure the F6000 for three Low Current 150 VA sources by
clicking User Defined on the F6000 Configuration display in ProTesT.
• Set the number of Current Sources to 0.
• Set the number of Convertible V/I Sources to 3.
• Set the Convertible V/I Source designations to I1, I2, and I3.
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 limits and the total harmonic
distortion (THD) is <2%.
3. Change the amplitude as shown in Table F.7.
Verify that the amplitude and distortion are within the limits.
4. Repeat step 3 for the 1 and 2 A range.
5. Repeat steps 2, 3, and 4 for Source I2 and I3.
Table F.7 on page F-10 lists the specifications for the 150 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.
