JD725A CABLE AND ANTENNA ANALYZER
Advanced Functions
The JD725A provides additional functions allowing superior analysis.
Trace Overlay
Trace Overlay allows comparative analysis of up to 4 traces by superim-
posing them together on one measurement graph.
Additionally, up to 6 markers can be set on any trace among multiple
traces to see its corresponding value.
Marker Bands
Marker Bands are user definable markers on frequency sub-bands
enabling a visual identification of uplink and downlink frequencies per-
forming compliance verification with a single measurement trace.
Smith Chart
The JD725A is capable of performing Smith Chart measurements to dis-
play on the site impedance of the antenna and transmission line.
