Measurement of transmitter output RF power has never been easier and more precise. AD8307 USB 0-500MHz RF Power Meter allows to measure the power of transmitters from 1nW to 2W / 50W with 40dB attenuator. Output is displayed in dBm, Watts (nW, uW, mW and W range) as well as input voltage. USB RF Power Meter is based on popular AD8307 watt meter IC and PIC18F2550 microcontroller.
Instead of using LCD display module the meter connects to a PC via USB port and displays measurements on a computer via USB RF Power Meter software. The software settings can be changed to use 10-50dBm attenuator and thus allowing to measure RF power higher than 2W.
RF attenuator is a simple resistor divider that allows AD8307 RF Power Meter to measure higher RF power than 2W. Two RF attenuator versions have been presented below. 20dB RF attenuator increases measurment range up to 20W while 40dB RF attenuator increases measurment range up to 50W. After connecting attenuator to RF Probe, remember to change attenuator value in Power Meter software from 0 to 20/40. All resistors are 1% metal film type with 1/4W rating. 40dB attenuator can measure RF power that is greater than 50W after replacing 1/4W resistors with higher wattage rating such as 1-3W.
Installing Drivers. Before AD8307 RF Power Meter can be used the following drivers must be installed. 1) Download and unzip it. 2) Connect RF Power Meter to computer using USB cable. 3) Windows will ask you if you want to install a driver.
Point it to drivers you unzipped. Windows 2000 / XP Under Windows 2000 or XP you will be prompted twice to install two drivers. On the first prompt please browse and point to MCHPUSB driver folder. On the second prompt please browse and point to USB CDC driver folder. Windows 7 / VISTA Under Windows 7 or VISTA you might be only prompted once to install USB CDC driver if MCHPUSB driver is already installed.
4) After the drivers are installed go to the Device Manager (right click on My Computer and click Properties-Hardware-Device Manager), and look under the Ports (COM & LPT) section, and you should see a new serial port there.

Because USB devices are Plug and Play devices, there is little that you can do to control or configure them. However, you can trace most USB problems to one of the following conditions:. Malfunctioning or incorrectly-configured hardware.
Malfunctioning, incorrectly-configured, or missing device driver. Mismatched cabling.
Out-of-date firmware or basic input/output system (BIOS). Incorrectly-configured root hub To fix your problem automatically in Windows, to download our driver installer utility, then run the download and follow the steps in this wizard. To fix your USB problem automatically to download our driver installer utility, then run the download and follow the steps in this wizard. To attempt to fix your USB problem manually, follow the steps below or click here to:. Click Start, click Run, type sysdm.cpl in the Open box, and then click OK. Click the Hardware tab. Click the Device Manager button.
Expand Universal Serial Bus controllers. Right-click every device under the Universal Serial Bus controllers node, and then click Uninstall to remove them one at a time. Restart the computer, and then reinstall the USB controllers. Plug in the removable USB device, and then test to make sure that the issue is resolved. Malfunctioning or incorrectly-configured hardware Typically, if you plug a malfunctioning or incorrectly-configured device into a USB port, it causes the computer to stop responding (hang). In most of these instances, you must physically turn off the computer and turn it back on to reset the bus. Be aware that it may be more difficult to identify which device is malfunctioning or is configured incorrectly.
If another computer that you know is working correctly is available, try to plug the device into that computer to see whether you encounter the same issue. If the device is plugged into a secondary hub, unplug the device from the hub, and then plug the device directly into the root hub. Many hardware problems (such as high or low power, bandwidth shortage, malfunctioning or incorrectly-configured firmware, and so on) can cause issues to occur. Check Device Manager to be certain that the root hub is functioning correctly.
If the root hub is displayed with an exclamation point (!) in a yellow circle, verify that the BIOS is assigning an interrupt request (IRQ) to the root USB controller. This is required for the device driver to be loaded. For more information about how to use Device Manager to troubleshoot hardware issues, click the following article number to view the article in the Microsoft Knowledge Base: 133240 Troubleshooting device conflicts with Device Manager If no devices work when you plug the devices into the root hub, verify that the power requirements of the bus are not being exceeded.
USB devices can draw a maximum of 500 milliamps for each connection. If a device tries to draw more power than this, the specification recommends that the computer should be able to disable that specific port until the computer power is cycled (this is known as 'suspending' the port). In addition, if the device draws less than 50 milliamps, the port never becomes active. Check the Power tab in USB Root Hub properties to check the power usage of the USB bus. Malfunctioning, incorrectly-configured, or missing device driver When you plug in a USB device, the computer should load and then configure the device without ever requesting a device driver (assuming that the device falls within the defined and supplied class drivers).
If the computer prompts you for a device driver, check with the manufacturer of the device to determine whether a driver is available. Mismatched cabling There are two types of USB cables, high speed and low speed. Low-speed cables differ from high-speed cables primarily in their shielding.
If you plug a high-speed device into a low-speed cable, you can cause signal distortion over long distances. Verify the USB chain is working correctly to be certain that a device that requires the ability to draw power from the hub is not plugged into the chain on the other side of a non-powered hub. This causes that hub and all devices down the chain to be suspended.
If the hub is a powered hub, verify that the power supply for that hub is configured correctly. Out-of-date firmware or BIOS The key to all USB devices is the firmware. The USB device's firmware contains all information about the device.
A port is not reset until all descriptors in the firmware have been loaded and verified by the root hub. This is important because it applies to items such as printers and modems. Make sure that you have the most up-to-date firmware that is available for both your computer's BIOS and each device. The symptoms of malfunctioning or incorrectly-configured firmware might be unusual. Typically, when you remove and then re-add a USB device, the device becomes available again.
However, the device may be displayed as a second instance of that device, and load itself as such in Device Manager. If you see duplicates of a device, verify that you have the most up-to-date firmware for that device. This issue is common with USB printers and modems.
A similar issue that has the same cause occurs when a device loads a device driver, and then adds a second device for which there seems to be no driver. The second device is displayed with an exclamation point in a yellow circle in Device Manager. The device may work correctly.
