Note on Horizontal Scaling
You can expand an acquired waveform vertically and horizontally on screen (but
not contract). Use the :DISPlay commands containing :X[:SCALe] or

for the setting range. Additionally, meet the following requirements for setting
the horizontal scale.
The horizontal display range set by the :DISPlay commands must be within the
data acquisition range set by the :SENSe commands (see Figure 2--6):
