Equipment: Oscilloscope, 50
Ω
, 20dB feedthrough attenuator
Preparation:
1. Configure the Oscilloscope follows:
Termination: 50
Ω
, 20 dB attenuator feed through at the
oscilloscope. Use identical cables to
connect the channels to the oscilloscope.
Setup: As required for the test
2. Connect 2074 Channel outputs to the oscilloscope input
3. Configure the 2074 as follows:
Waveform: Arbitrary
SCLK: 200
MS/s
Amplitude: 6 V
Output: On
Test Procedure
1. Using ArbConnection prepare and download the following
waveform (all channels):
Wavelength: 1024
Waveform: Square
2. Measure the skew between channels 1 and 2 to be less than 2
ns.
3. Measure the skew between channels 3 and 4 to be less than 2
ns.
4. Measure the skew between channels 1 and 3 to be less than 7
ns.
5. Modify the phase offset parameters on channels 2, 3 and 4 from
-10 to 10 and check that the phase offset between channels is
increased by 5 ns with every phase offset step.
