The 140-525 Antenna Analyst combines a microprocessor controlled 135-525 MHz frequency synthesizer with an accurate low-power directional coupler to present a graphical display of Return Loss or VSWR versus frequency. To create these graphical displays, the Analyst continuously sweeps and plots the user-selectable frequency range. You can define this frequency "sweep" range as well as take measurements within a plot, using the Analyst's dedicated keys. More specialized functions are embedded within a system of menus that you can access using the top row of "softkeys", labeled F1-F-5. Once installed on your PC, Analyst Director software allows you to remotely control the Analyst, as well as save and print. Director users enjoy increased efficiency and real time data flow.

NOTE: It is possible to remotely control the Analyst from an ASCII terminal, however, data flow is slightly delayed.
