I see the RF meter only shows frequencies 2.4-2.5 gHz? Is this the only part of the RF spectrum it measures?

What frequencies, exactly, does this unit measure?

How can I see frequencies in the 1.9-2.0 gHz range?

Hi mberger47,

The RF general detection is from 1Mhz to 10Ghz in one band (but you cannot see the specific RF frequency.

Only RF Spectrum Analyzer feature split into 6 band:
Band 1: 150KHz 531KHz
Band 2: 520Khz 1710KHz
Band 3: 64MHz 108MHz
Band 4: 2.3MHz 23.00MHz
Band 5: 240MHz 1040MHz
Band 6: 2.4GMhz 2.5GMHz (the one you are loooking at)
To change the band, you can hold the down button and then select which band you want to check.

It doesn't have spectrum for 1.9GHZ -2.0GHz.

Thank you for the explanation. When I see readings for "RF" spectrum - what is it actually measuring? 1Mhz to 10Ghz? Like in the All-in-one display.

RF Spectrum mode is not the same as the RF in AllInOne display. The AllInOne display uses the 1MHz-10Ghz band(we usually call this general RF because it can't show frequency), 240MHz 1040MHz band, and the 2.4GMhz 2.5GMHz band.
In RF Spectrum, you can see how strong is a specific frequency. Like 2.445GHz for example you can see the RF density in that frequency. Like if you're using a microwave, you can see which frequencies in 2.4GMhz 2.5GMHz it's using and how strong they are. But in AllInOne mode, you can only see the power density and not specific frequency.

Yes, so I am seeking clarity here. If the RF AllInOne display shows 1 microwatt per cm2, is device measuring 1 microwatt per cm2 in the 2.4GMhz 2.5GMHz range or 1 microwatt per cm2 in the 1MHz-10Ghz range?

Its from the 1MHz-10Ghz range.
