Changing the I or Q Waveform Window

If the I or Q Waveform window is active in the I and Q Waveform view, the SPAN X Scale and AMPLITUDE Y Scale keys access the menu to modify the following parameters:

•With the SPAN X Scale key:

—Scale/Div - Allows you to set the horizontal scale by changing a time value per division. The range is 1.00 ns to 1.00 s per division. The default setting is 18.8 ms per division. However, since the Scale Coupling default is On, this value is automatically determined by the measurement results. To manually set this value Scale Coupling must be Off.

—Ref Value - Allows you to set the reference value ranging from

−1.00 to 10.0 s. The default setting is 0.00 s. However, since the Scale Coupling default is On, this value is automatically determined by the measurement results. To manually set this value Scale Coupling must be Off.

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

—Scale Coupling - Allows you to toggle the scale coupling function between On and Off. The default setting is On. Upon pressing the Restart front-panel key or Restart softkey under the Meas Control menu, this function automatically determines the scale per division and reference values based on the measurement results.To manually set either Scale/Div or Ref Value values, Scale Coupling must be Off.

•With the AMPLITUDE Y Scale key:

—Scale/Div - Allows you to set the vertical scale by changing the amplitude value per division. The range is 1.00 nV to 20.00 V per division. The default setting is 100.0 mV. However, since the Scale Coupling default is On, this value is automatically determined by the measurement results. To manually set this value Scale Coupling must be Off.

—Ref Value - Allows you to set the reference value ranging from

−250.00 to 250.00 V. The default setting is 0.00 V. However, since the Scale Coupling default is On, this value is automatically determined by the measurement results. To manually set this value Scale Coupling must be Off.

—Ref Position - Allows you to set the reference position to either Top, Ctr (center) or Bot (bottom). The default setting is Ctr.
