The A3008, when plugged into the same LWDAQ Multiplexer, can create bad messages in a Data Receiver ( A3018 ). Set the A3008 local oscillator to its minimum (DAC count 0) or maximum (DAC count 255) frequency to reduce the bad message rate. Even better: unplug the A3008 when you`re not using it. The RF Spectrometer (A3008) measures RF powe

r in 3-MHz windows between 850 MHz and 1100 MHz. If you connect the A3008`s RF input to an antenna, the A3008 will measure the power spectrum of RF signals arriving at the antenna with 1-MHz resolution and sensitivity 10 pW ( ’80 dBm). You can use the A3008 to measure average power or peak power. If you would like some help with radio-frequency jargon, see our presentation of Terminology. The A3008 is a LWDAQ device. The LWDAQ software `s RFPM Instrument (radio frequency power meter) obtains RF power measurements from the A3008 and the Spectrometer Tool gathers these power measurements together into a graph. The A3008 allows us to measure the ambient radio frequency power in the 875 MHz to 1050 MHz range, so that we can choose a 20-MHz wide band free of interference in which to operate our Subcutaneous Transmitter ( A3009 ). We can also use the A3008 to measure the power received by an antenna from such transmitters, even though the transmitters are active for only 7 s out of every 2000 s. The A3008, combined with the RFPM instrument, allow us to measure peak power received rather than average power, and this peak power will detect the bursts of power from our transmitters. The A3008 uses an eight-bit DAC to set the TUNE input of a MAX2624 VCO. For DAC values 0 to 255, the VCO output frequency increases from roughly 850 MHz to 1050 MHz. The A3008`s RF input is amplified and passes into a mixer, where it is downshifted by...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
