Setting The Delta Marker In The Trace Bandwidth Analysis - Agilent Technologies 4294A Operating Manual

Step 4. Select the definition of the cutoff point in trace bandwidth analysis from the following:

Fixed value (specified by numerical value)
1. MKRVAL: Indicates the measurement parameter value (measurement) at the position of
the main marker (marker 0).
Fixed value: Indicates the absolute value of the measurement parameter if there is no D
marker; it is a relative value with reference to the tracking D marker if tracking (D
marker that moves with the main marker) is present and a relative value with reference
to the fixed D marker if the fixed D marker is present.
Step 5. When the fixed value is selected (using the
(measurement parameter value) to define the current cutoff point is displayed in the set
parameter value field in the upper left area of the screen.
Step 6. Use the keys or rotary knob of the ENTRY block in one of the following ways to specify
the fixed value of the cutoff point.
• Enter the desired value with the numeric keys (
of the unit keys (
• Turn the rotary knob (
• Press the step keys ([­][¯]) to set the desired value.

Setting the delta marker in the trace bandwidth analysis

The definition of each parameter obtained in the trace bandwidth analysis varies depending
on the delta marker mode selected at the time. Before executing the trace bandwidth
analysis, select the delta marker mode. If you use the fixed delta marker mode, set the delta
marker position also.
Step 1. Activate the trace for which you want to perform the trace bandwidth analysis.
