Field Strength Meters

 

Precision Test Systems supplies three types of field strength meters / analyzers.  Also a matching range of field signal generators are available to complement the FSM series to provide a complete propagation measurement system.

FSM Series of Field Strength Meters

The FSM series of field strength meters will measure the strength of a RF signal appearing at its input from +20 dBm to -110 dBm for wide bandwidth models and +10 dBm to -120 dBm for narrow bandwidth models. The RF strength will be displayed on an LCD display to an accuracy of ±3 dB over the entire 130 dB dynamic range. A matching field signal generator is also available to act as a signal source for propagation studies.

 

  • Many models to choose from covering  the 20 MHz to 3 GHz frequency range

 

  • 130 dB dynamic range. Measures from +20 dBm to -110 dBm or +10 dBm to  -120 dBm depending upon what bandwidth is chosen

 

  • Frequency range and step size can be altered to customer's requirements upon special request

 

  • Handheld portable units operating on rechargeable batteries. Typically five hours use between charges

 

  • Fast log detector enables GSM or digital signals to be captured as well as normal CW signals

 

 Applications

The FSM series of field strength meters are ideal for the following applications:

1. Propagation study or mapping of radio systems including analog and digital systems.
2. Measurement of antenna performance of a cellular phone or two way radio.
3. Direction finding using a directional antenna.

Three modes of operation, namely CW, PULSE or MAX-HOLD enables the FSM series to measure normal analog CW signals as well as pulse signals such as encountered in GSM cellular systems or avionics systems. The FSM series log amplifier has a fast response enabling short bursts of signals to be captured and displayed to an accuracy of ±3 dB.
