1. Stimulus Start Value. This value could be any one of the following:
• The start frequency of the source in frequency domain measurements.
• The start time in CW mode (0 seconds) or time domain measurements.
• The lower power value in power sweep.
When the stimulus is in center/span mode, the center stimulus value is
shown in this space. The color of the stimulus display reflects the current
active channel.
2. Stimulus Stop Value. This value could be any one of the following:
• The stop frequency of the source in frequency domain measurements.
• The stop time in time domain measurements or CW sweeps.
• The upper limit of a power sweep.
When the stimulus is in center/span mode, the span is shown in this space.
The stimulus values can be blanked, as described under the
FREQUENCY BLANK
Reference."
(For CW time and power sweep measurements, the CW frequency is
displayed centered between the start and stop times or power values.)
3. Status Notations. This area shows the current status of various
functions for the active channel.
The following notations are used:
