The Sweep Time key under the Meas Setup menu controls the horizontal time span for this measurement, while the SPAN X Scale key allows you to access the menu to modify the horizontal parameters common to the rectangular windows for this measurement:

•Scale/Div - Allows you to set the horizontal scale by changing a time value per division. The range is 1.0 ns to 1.000 s per division with

0.01ns resolution. The default setting is 200.0 ∝s per division. However, since Scale Coupling is defaulted to On, this value is automatically determined by the measurement result.

•Ref Value - Allows you to set the reference value ranging from −1.0 to

10.0s. The default setting is 0.00 s. However, since Scale Coupling is defaulted to On, this value is automatically determined by the measurement results.

•Ref Position - Allows you to set the reference position to either Left, Ctr (center) or Right. The default setting is Left.
