Can this measure frequencies up to 40MHz? Has anyone tested it? The spec sheet on their site says 40MHz.

I tested it with my 200Mhz Arb. Gen. - At 10Vpp sine and square it seems to max out at ~33Mhz. - At 5Vpp it maxes out at ~23Mhz. - At 2.5Vpp it maxes out at ~13Mhz. My Arb. Gen. Maxes out at 10Vpp. The EX330 may go up to 40Mhz, but it is going to need a signal at more than 10Vpp so I'm not sure how useful this meter would be.

OK first off NO this meter can not measure 40 mhz !!the spec's say only to 10 Mhz !!and just so you know this is for sine wave's only and not RMSNow my Qusestion to you is why do you want a meter to measure 40 Mhz ??As for my assement of this meter its one of the most bang for your Buck !!its a great meter !!!(for the price)now why do you need to mesurea 40 mhz there are many very afforadable DSO that you can get for $300-$400 dollars that will measue Freq and voltage.anyway wish you luck anyt more Question feel Free to Ask:)

The manual , unfortunately is written in Chinglish, and they are probably referring to a much higher frequency, and this stateme t made it past the spell checkers & context checkers. Otherwise the other answers proffered for this are certainly valid, referringto 50Hz, AC Line interference & aliasing, from domestic Japanese , Chinese, & UK sources of 50 Hz power & frequency deviation..

According to the manual, which you can find at the Extech website, measurement band is 300Hz to 8KHz.

I heard you have to enter the frequencies with a computer app. Do not know what it is.

The one I received says 45db in the manual. I have not tested that with a meter to see if it's accurate.

No. The meter is set for microwave-oven frequency over a certain range. I think it is too microwave oven-specific for accurate cell phone radiation readings.

You simply press a button that toggles between 1kHz and 440Hz - easy as cake. I've only ever used it to test from the XLR output, but when I get a chance later today I'll test it out. Edit: The test tone does indeed generate from all outputs!

Although I have not used it to scan police frequencies, the range of this radio does cover the150 and 450 MHz bands that are commonly used. Municipalities are often using other methods rather than FM for communications these days.

John, this is primarily designed for Amateur radio TRANSMITTING. So it's at best efficient at the frequencies it's designed for. Will it work on higher frequencies? Yes it just will not be as well tuned for higher freq. You should be able to hear local PS stations.

It only does set frequencies -- 20-, 28-, 32-, 42-Hz ... up to 150 KHz. Note that there is a fair amount of variation between selected frequency (e.g. 100 Hz) and actual output (e.g. 101.4 Hz), so I would not use it to calibrate frequency devices without a secondary measurement instrument (DVM,Tach, etc.) to verifiy frequency. It is a great little portable inexpensive battery-powered signal source -- TSA allows it to be carried on a plane too. We have a purchased around a dozen over the years. You can adjust amplitude of Sin/Sqr waveform with pot in upper right and the -20db toggle can be handy as well. It only does set frequencies -- 20-, 28-, 32-, 42-Hz ... up to 150 KHz.

I have used this meter for my Ham radio on the HF bands (160 thru 10 meters). It might work on the VHF bands but would be very inaccurate. It will read field strength on 2 meters, as it has registered on the meter using my 2 meter HT. Hope this helps. For the price it is usable, but the accuracy is not great. If used to tune an antenna to minimum VSWR it will work, but the power out it reads will not be that accurate.

I'm not sure I understand what you are asking. It's powered by a USB cable from your PC and it will display 60Hz, which is within it's range of 0-250kHz. Perhaps you would be well served by checking out some of the videos on YouTube.

Update. It works fairly well on the aircraft band RECEIVE ONLY. I was able to scan the air band and pick up close to a dozen aircraft frequencies in use.It still cannot transmit on aircraft frequencies. And even if it did, it only transmits FM while aircraft transmission is AM, so nobody could understand you even if you did transmit.

Nope, after 8 months, my kids still use it quite frequently! :) Seriously though, purchased November 2013, ours is 27MHz

I have to say fixed frequency , I think it runs in the 660 to 880 MHz range depends on what else you use in that range, even then what are the odds of anything being on that same freq.

The meter displays in dBC, frequency range of 31.5Hz-8KHz. Meter works great. Nice compact design.

The info listed doesn't say if it will work properly on 50Hz. The best would be to use a true RMS meter, or do some more research on Flukes's website.
