Features
Swept Frequency Mode
Fast scan shows VSWR, ρ, match efficiency or return
loss across an entire band. A movable cursor can be
used to pinpoint a scan frequency and the correspond-
ing measurement value is displayed.
Single Frequency Mode
Provides measurement information in units of Reflec-
tion Coefficient (
ρ); Voltage Standing Wave Ratio
(VSWR);% Match, or Return Loss (dB) at one fre-
quency on a simulated meter movement. An audio
generator can be enabled to produce a tone that is pro-
portional 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.
