The channel status bar is located in the bottom part of the channel window (See figure below).
Channel Status Bar
It contains the following elements:
•Stimulus start field allows display and entry of the start frequency or power, depending on the sweep type. This field can be switched to indicate the stimulus center frequency, in this case the word «Start» will change to «Center». For a detailed description of stimulus setting, see Sweep Range.
•Number of Points field allows display and entry of the number of sweep points. The number of points can be set from 2 to 16001. For a detailed description see Number of Points.
•Sweep type field allows display and selection of the sweep type. The values of this field are represented in the table below. For a detailed description see Sweep Type.

•IF bandwidth field allows display and setting of the IF bandwidth. The values can be set from the 10 Hz to 30 kHz. For a detailed description see IF Bandwidth Setting.
•Power level field allows display and entry of the port output power. In power sweep mode, the field switches to indicate the CW frequency of the source. For a detailed description see Stimulus Power.
•Stimulus stop field allows display and entry of the stop frequency or power, depending on the sweep type. This field can be switched to indication of stimulus span, in this case the word «Stop» will change to «Span». For a detailed description of stimulus setting, see Sweep Range.
•Error correction field displays the integrated status of error correction for S-parameter traces and the integrated status of power correction for all the traces. The values of this field are represented in the table below. For a detailed description see Error Correction Status.
