Making Measurements
Making the Waveform (Time Domain) Measurement
• 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.
If the
Signal Envelope window is active in the Signal Envelope view, the
AMPLITUDE Y Scale key accesses the menu to modify the following
parameters:
•
Scale/Div - Allows you to set the vertical scale by changing an
amplitude value per division. The range is 0.10 to 20.00 dB per
division with 0.01 dB resolution. The default setting is 10.00 dB 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
−250.00 to 250.00 dBm. The default setting is 0.00 dBm. 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 Top, Ctr
(center) or
Bot (bottom). The default setting is Top.
•
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.
If the
I/Q Waveform window is active in the I/Q Waveform view, the
AMPLITUDE Y Scale key accesses the menu to modify the following
parameters:
•
Scale/Div - Allows you to set the vertical scale by changing an
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
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
−250.00 to 250.00 V. The default setting is 0.00 V. 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 Top, Ctr
(center) or
Bot (bottom). The default setting is Ctr.
•
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.
