FMUSER PM-1A 5200W RF Power Meter
Description
An RF power meter or microwave power meter is a professional instrument that measures the electrical power of a device, usually at microwave frequencies from 100 MHz to 40 GHz.
Besides, an RF power meter is mainly used to collect information, analyze, measure, and calculate RF power and radio antenna VSWR, and display it on the built-in screen. Or display the analog data in digital form on the app.
Features
1.Real-time APP Monitoring for RF Commissioning Data
FMUSER PM-1A RF Power Meterwith BT mobile phone APP monitoring function The digital design significantly improves the readability of RF data, meanwhile, it enables a quick APP monitoring for the RF engineers of the following parameters:
- Open the BTsettings before the test starts
- Make sure the BT of the FMUSER PM-1A RF power meter is connected to your mobile phone
- Turn on your transmitter (ALWAYS connect the antenna/dummy load ahead)
- Commission the transmitter while monitoring
2. Get Away from High-Cost Dilemma at the same time high precision
As far as we know,the price of an RF power meter from some typical suppliers is generally set in thousands of dollars, but many customers still place their orders because there are no such alternatives. RF power meters with high cost and poor accuracy were the only option for most FM radio station engineers. However, the launch of the FMUSER PM-1A RF power meter perfectly solves the problem.
only 1/4 the price of RF power meters from other famous brands but 4 times precision as higher as any one of theirs in the 85 -110Mhz band. You won't get such a high-quality fixed-band RF power meter from other suppliers.
3.High-precision professional test solutions
Selecting an RF power meter of high quality also helps decide how you will run the transmitter and antenna daily maintenance in your radio station. But in fact, if you want higher monitoring accuracy of the FM transmitter output power, the absolute value of the frequency range and acceptable power range of the RF power meter must be smaller
The core accuracy readings of the FMUSER PM-1A RF power meter are as follows:
- Tested accuracy ±10% at a 0-200W rated power range
- Tested accuracy ±3% at a 200-1,000W rated power range
- Tested accuracy ±2% at a 1000-5,200W rated power range
The FMUSER PM-1A RF power meter focuses on an exact rated power that can reach as low as 2 watts and as high as 5,200 watts. Additionally, with a fixed frequency range of 85-110MHz (FM band covered), rather than kHz, GHz, or thousands of MHz, FMUSER PM-1A can be well applied to all broadcast transmitters in the FM band (88-108MHz, 0-5.2kW)
4. Long service life and robust design
- The aluminum alloy cavity brings a rugged and durable design for daily commissioning.
- Best for a long time and bumpy transportation such as in remote mountainous areas.
- Unlike a pointer meter, there will be no precision offset will be produced during the transportation of the FMUSER PM-1A RF power meter.

3. On-site Testing with an RF Power Meter
Generally, when engineers need to conduct on-site testing for FM transmitters, few pieces of broadcasting equipment are needed.
- Broadcast equipment to be tested: e.g. high power FM broadcast transmitters Antenna/dummy load: for eventual transmission of the broadcast RF signal from the transmitter
- Feeders/cables: Connect transmitter and antenna or dummy load, transmit RF signal
- RF power meter: used to match the frequency of the device under test: e.g. 50-200MHz (VHF) RF wattmeter
- Other related devices: RF power sensors, and spectrum analyzers. The maintenance engineers will select power sensors based on frequency range, dynamic range, and modulation format, dues to limited space, this topic will not be introduced here.
- The engineer will ensure that all equipment is wired separately before powering on the transmitter, including:
- Connect the audio source-FM transmitter line: including the transmitter's power supply, RF output, audio input, etc.
- Connect the FM broadcast antenna/RF dummy load line: including RF input (feeder/feeder), antenna installation (check positive and negative poles, antenna installation height, multi-layer antenna spacing)
- Choose the right RF power meter: including matching the frequency of the broadcast transmitter and the power sensor connector (high-power FM transmitters need to be connected to the feed pipe, so you may need to choose an RF power meter with a flanged head)
- When everything is ready, the engineer will connect each device according to the order of "broadcast transmitter-RF power meter-antenna/dummy load".
- The last step is to turn on the power of the broadcast transmitter, adjust the input power and observe the RF power meter RF power and VSWR values displayed on the meter
