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.
n
The upper limit of a power sweep.
When the stimulus is in center/span mode, the span in this space. The stimulus
values can be blanked, as described under Key” in the “Key
chapter.
(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:
Avg = Sweep-to-sweep averaging is on. The averaging count is shown immediately
below (See Key” in the “Key Definitions” chapter.)
Error correction is on. (For error-correction procedures, refer to the “Optimizing
Measurement Results” chapter. For error correction theory, refer to the
“Application and Operation Concepts” chapter.)
Cor =
CA Stimulus parameters have changed from the error-corrected state, or interpolated
error correction is on. (For error-correction procedures, refer to the “Optimizing
Measurement Results” chapter. For error correction theory, refer to the
*Application and Operation Concepts” chapter.)
Full two-port error-correction is active and power range for each port

occurs because the analyzer does not switch between the test ports every sweep
under these conditions. The measurement stays on the active port after an
initial cycling between the ports. (The active port is determined by the selected
measurement parameter.) You can update all the parameters by pressing

Note
On instruments equipped with Option 007, should be displayed at all times if
a full two-port error-correction is active.
Del = Electrical delay has been added or subtracted, or port extensions are active. (See
the “Application and Operation Concepts” chapter and Key” in the
“Key Definitions” chapter.)
ext
Waiting for an external trigger.
Ofs = Frequency offset mode is on (Option 089 only). (See “Frequency Offset
Operation” in the “Application and Operation Concepts” chapter.)
Of?
Frequency offset mode error (Option 089 only), the IF frequency is not within
10 MHz of expected frequency. LO inaccuracy is the most likely cause. (See
“Frequency Offset Operation” in the “Application and Operation Concepts”
chapter.)
Gat = Gating is on (time domain Option 010 only). (For time domain measurement
procedures, refer to the “Making Measurements” chapter. For time domain
theory, refer to the “Application and Operation Concepts” chapter.)
