Instrument Overview 2-8 Symbols and Indicators
MS20xxB UG PN: 10580-00301 Rev. D 2-17
VNA Port-2 (50 ohm)
This connector (refer to item “11” in Figure 2-9 on page 2-13) provides the input 50 ohm
interface for transmission measurements of the Vector Network Analyzer at Port 2. Bias Tee
output is also available from this port (with Option 10).
To prevent damage to your instrument, do not use pliers or a plain wrench to tighten the
Type-N connector. Do not overtighten the connector. The recommended torque is 12 lbf·in to
15 lbf·in (1.36 N·m to 1.70 N·m).
2-8 Symbols and Indicators
The following symbols and indicators indicate the instrument status or condition on the
display.
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 2-6). 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 Appendix A.
Battery Symbols
The battery symbol above the display indicates the charge remaining in the battery. The
colored section inside the symbol changes size and color with the charge level.
Green: Battery is 30% to 100% charged
Yellow: Battery is 10% to 30% charged
Red: Battery 0% to 10% charged
Lightning Bolt: Battery is being charged (any color symbol)
Detailed battery information is also available in the Status dialog box (System > Status).
