Using the Marker Feature to Determine the Test Signal Level
You can use the main marker to determine the test signal level at your desired point on the
trace. Once you have turned on the test signal level monitor feature, the Agilent 4294A
preserves the test signal level value monitored for each measuring point on the trace during
the sweep cycle. This allows you to identify the signal level monitored for each measuring
point even with the sweep cycle in the hold state.
NOTE You can place the marker at any measuring point on the trace to determine the signal level
monitored at that point, regardless of whether your sweep parameter is frequency, signal
source level, or dc bias level.
Step 1. Press the
[Display] key to display the Display menu.
Step 2. Press the
OSC MON on OFF key to turn on the test signal level monitor feature (pressing
the key toggles your selection).
Step 3. If the sweep cycle is currently in the hold state, specify the number of sweep cycles (see
“Specifying Sweep Times and Stopping Sweep” on page 114) and then start testing the
DUT by specifying the trigger source (see “Selecting a Method to Start Measurement
Softkey Labels Description
