This section describes the Couple(1) menu displayed when the COUPLE key is pressed.
RBW AUTO/MNL
Toggles the resolution bandwidth between AUTO and MNL.
AUTO:
Automatically sets an optimum resolution bandwidth
based on the current span.
MNL:
Allows you to set the resolution bandwidth manually.
VBW AUTO/MNL
Toggles the video bandwidth between AUTO and MNL.
AUTO:
Automatically sets an optimum video bandwidth based
on the resolution bandwidth.
MNL:
Allows you to set the video bandwidth manually.
Sweep Time AUTO/MNL
Toggles the sweep time between AUTO and MNL.
AUTO:
Automatically sets an optimum sweep time based on
the span.
MNL:
Allows you to set the sweep time manually.
All Auto
Automatically sets an optimum resolution bandwidth, video
bandwidth and sweep time based on the span.
RBW:Span ON/OFF
Toggles the "span vs. resolution bandwidth" function on or off.
This function can be used only when the RBW is set to AUTO.
ON:
The ratio of "RBW vs. span" can be changed.
OFF:
The value represented by the ratio of "span vs. resolu-
tion bandwidth" is 0.01:1.
NOTE
If "Trace Point" is set to a value lower than the value calcu-
lated by Span/RBW, the level may not be displayed correctly.
If this happens, set "Trace Detector" to "Positive."
VBW:RBW ON/OFF
Toggles the "resolution bandwidth vs. video bandwidth" function
on or off.
This function can be used only when the VBW is set to AUTO.
ON:
The ratio of "VBW vs. RBW" can be changed.
OFF:
The value represented by the ratio of the resolution
bandwidth to the video bandwidth is 1/1.
