Features
Swept Frequency Mode
Fast scan shows Voltage Standing Wave Ratio
(VSWR); Reflection Coefficient ( ρ); % Match, or Return
Loss (dB) across an entire band. A movable cursor can
be used to pinpoint a scan frequency and the corre-
sponding measurement value is displayed.
Single Frequency Mode
Provides measurement information in units of VSWR,
ρ, match efficiency or return loss 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
Verifies output of portable cellular phones with fixed
antennas.
Cellular System Presets
Pre-programmed band segments for AMPS, GSM,
PDC, CT-2, and CT-2 Korea cellular testing.
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.
