Inter-Channel Skew
Calibration
(AWG7102 and AWG7052)
This calibration is required to ensure that the Ch 1 and Ch 2 output skews are set
within the specified range. This calibration is applied to both analog and marker
outputs.
1. Install the test hookup and preset the instrument controls:
a. Hook up the sampling oscilloscope:
„
Attach the SMA terminations to the Channel 1 Analog (–) Output,
Channel 2 Analog (–) Output, and Marker 1 (–) Output on the front
panel of the arbitrary waveform generator.
„
Connect an SMA cable from the Channel 1 Analog (+) Output on the
front panel of the arbitrary waveform generator to the CH 1 Input of
the sampling oscilloscope using the SMA attenuator, as shown in
Figure 3-6.
„
Connect an SMA cable from the Channel 1 Marker (+) Output on the
front panel of the arbitrary waveform generator to the TRIGGER
DIRECT INPUT of the sampling oscilloscope using the SMA
attenuator, as shown in Figure 3-6.
