The instrument settings that are unique to each trace are summarized in an information block on the left side of the measurement display screen (refer to item 1 in Figure: VNA Display with GPS On). Each block contains the trace number followed by the S‑parameter that is assigned to that trace (TR4: S21, for example). If the trace has Trace Math applied to it, then the math function is also displayed on that line (TR1: S11/M1, for example), where M1 is the memory that is associated with TR1, and the math function is Trace/Memory). The S‑parameter that is assigned to the trace memory is shown (if enabled) at the top of each trace information block (M1: S11, for example). Each trace block also includes the Graph type, the smoothing percentage, the calibration status, and the scale (Resolution per Division and the Reference Value). The calibration status indicates whether the calibration is ON, OFF, or non‑existent (--) for the specific S‑parameter that is assigned to each trace. If the Calibration is ON, then its validity is also displayed (OK,?, or X).
For calibration procedures, refer to the Cable and Antenna Measurement Guide (PN: 10580‑00241) listed in Supplemental Documentation.
