Taidacent Power Meter Calibration Power Measurement 1MHz ~ 10GHz -50~0dBm Power Attenuation Value Can be Set

For an inexpensive power meter this is quite good. Get a 20 dB SMA attenuator so you can measure power up to 100 mW. But the unit is reliable and very easy to use.

It seems fairly accurate, from measuring against other things, within .1-.2dB. It would be perfect if it remembered its attenuation level when turned off. Well, and if it worked with +5V, +7V is a little less convenient.

This is the 3rd unit I bought for projects and it just works. You will need to make a correction table for calibration over the frequency range, but that is true for any power meter that doesn't store internal correction tables.

I built a handy RF level tester by mounting this circuit board in the plastic case which it was shipped in. Comparing its readout with that of some signal generators, I believe that it is pretty accurate except when getting to the measurement extremes. In other words, when the applied signal lever approaches 0dBm or -50dBm, amplitude reading isn't as accurate. In the middle of the amplitude range it seems pretty good. With use of external attenuators, its upper range can easily be extended. This has become a handy checker of signal generators that I work on and other oscillator devices.

This unit exceeds my expectations which is something I rarely am able to state . Great job guys !!

Very accurate and easy to use.

I spot calibrated it with a signalhound tracking generator in CW and spectrum analyzer at -10, -20, and -30 dBm. consistently reads 3.5+/-1 dB hot over 1 GHz to 3 GHz, but with a bit of work you could probably create curves that got you within half a dB of truth. Haven't tried it with a modulated input yet.

Love this product, you can use it as a power meter to measure the attenuation for a RF switch . Highly recommended.

This is a very inexpensive microwave measuring instrument! A game changer indeed.
