We like this calibrated wideband(800 MHz - 2.5 GHz)RF meter because it has a switch which allows a choice of peak or average indication mode. This permits accurate measurement of both digital and analog signals. Two ranges: 1 - 1999 µW/m² (same as0.1 - 199.9 nW/cm²) and 0.1 - 199.9 µW/m² (same as0.01 - 19.99 nW/cm²).
In addition, you get a choice of audio tone - none, or intensity proportional to field strength, or proportional to frequency (for analyzing pulsed signals)
- accuracy ±6 dB
- true logarithmic - periodic antenna, 800 MHz - 2.5 GHz, single polarized, included
- standard 9V battery included
The display on the HF35C updates every 0.5 second. The fastest pulse it can detect is 0.5 micro seconds.
When in peak mode, the display averages all peaks within ½ of a second. The average peak is displayed on the display.
In RMS mode it displays the true average of all signals during that ½ second period. This reading is much lower than Peak mode when measuring a digital signal.With OptionalNear Field Antennathis emf meter can be used as a near field meter capable of measuring smart meter shields, router shields and cellphone shields as well as demonstrating the shielding effectiveness of rf shielding fabrics.
