Ω
– Output grounding configuration: Floating ground
– Waveform: Square
– Output state: ON
4
Set both the U8903B output channels to be tested to produce a square wave with
amplitude of V
DUT
and frequency of 1 kHz
as given in the “
amplitude accuracy verification
5
Set both the digital multimeter range as given in the “
amplitude accuracy verification
6
Enable the U8903B output channels.
7
Record the sine wave amplitude voltage measurement on the digital multimeters,
V
DMM
in the “
Test record for square wave amplitude accuracy verification
.
8
Compute the square wave amplitude accuracy using the following equation:
Sine wave amplitude accuracy = (V
DMM
– V
DUT
) / V
DUT
×
100
9
for the rest of the V
DUT
to complete the verification of the
U8903B output channel to be tested.
10
Compare the recorded amplitude measurement values to the specification. If the test
fails, adjustment will need to be carried out accordingly.
