General Notes

Note

Basic features include: Swept Frequency Mode — Fast scan shows VSWR, , match efficiency or return loss across an entire band. A movable cursor can be used to pinpoint a scan frequency and the corresponding measurement value is displayed. Single Frequency Mode — Provides measurement information in units of Reflection Coefficient (p); Voltage Standing Wave Ratio (VSWR);% Match, or Return Loss (dB) at one frequency on a simulated meter movement. An audio generator can be enabled to produce a tone that is proportional to the match condition. Auto Scaling — Used in either swept or single frequency modes, sets the Y axis for best measurement display. Relative Field Strength — Provides means for optimizing the radiated signal of any transmitter within the specified frequency band. Limit Testing — Quick pass-fail indication; compares measurements to user selected limits. Data Storage — Saves and recalls up to 12 traces to be used to set limit or long term monitoring of antenna performance. Serial Communication Link — Built in serial port and optional software uploads data to a personal computer for analysis or storage.
