Operating Concepts
Channel Stimulus Coupling
Minimum Sweep Time
The minimum sweep time is dependent on the following measurement parameters:
• the number of points selected
•IF bandwidth
• sweep-to-sweep averaging in dual channel display mode
• error-correction
• type of sweep
In addition to the these parameters, the actual cycle time of the analyzer is also dependent on the following
measurement parameters:
• smoothing
• limit test
•trace math
• marker statistics
Refer to Chapter 1, “Specifications and Regulatory Information” to see the minimum cycle time values for
specific measurement parameters.
Channel Stimulus Coupling
COUPLED CH on OFF, toggles the channel coupling of stimulus values. With COUPLED CH ON, (the
preset condition), both channels have the same stimulus values. (The inactive channel takes on the
stimulus values of the active channel.)
In the stimulus coupled mode, the following parameters are coupled:
•frequency
• number of points
•source power
• number of groups
•IF bandwidth
• sweep time
• trigger type
• sweep type
• power meter calibration
Coupling of stimulus values for the two channels is independent of DUAL CHAN on OFF, in the display
menu and MARKERS: UNCOUPLED, in the marker mode menu. COUPLED CH OFF, activates an
alternate sweep function when dual channel display is on. In this mode, the analyzer alternates between
the two sets of stimulus values and displays the measurement data of both channels.
Sweep Types
The following sweep types will function with the interpolated error-correction feature:
• linear frequency
• power sweep
•CW time
The following sweep types will not function with the interpolated error correction feature:
