SparkFun FM Tuner Basic Breakout
Si4703
This breakout for the Silicon Laboratories Si4703 FM tuner chip is a little more stripped down than our FM Tuner Evaluation Board. If your project already has an amp and just needs a full-featured FM tuner, this is the board for you. Beyond being a simple FM radio, the Si4703 is also capable of detecting and processing both Radio Data Service (RDS) and Radio Broadcast Data Service (RBDS) information. The Si4703 even does a very good job of filtering and carrier detection. It also enables data such as the station ID and song name to be displayed to the user.

Telemetry Transmitter for FM with up to 3 Bands
LS-11-F
The LS-11-F portable FM test transmitter is designed for checkout and troubleshooting of telemetry receiving systems operating with FM modulation. For applications with any of the ARTM modulations (Tier 0, Tier I, or Tier II), please refer to the LS-11-M Data Sheet. Complete ground stations including the antenna with LNA, RF down-converter, IF receiver, bit synchronizer, and PCM decommutator can be tested and bit error tests performed. The design allows secure links to be tested with an external encryptor. The Test Transmitter contains an internal PCM Data Simulator and Pseudorandom patterngenerator that operates in a BERT mode. The device provides simulated clock and data (without transmitter enabled) and accepts external data for modulating the internal transmitter. Complete setup can be achieved locally through the keypad and two-line LCD display or remotely through the USB Interface. Operational parameters include the PCM format parameter database information (frame sync patterns, wavewords, etc…), pre-modulation filter selection, transmitter carrier frequency, transmitter deviation, and output power level. Output power can be selected from approx. -60 to +5 dBm in 5 dB steps.

Proactive Downstream Spectrum Analysis
SpectraVizion
SpectraVizion is an innovative, software-based diagnostics tool that leverages new advancements in remote spectrum capture, allowing cable operators to address downstream spectrum impairments proactively, before subscribers call in with service complaints. “Troubleshooting downstream spectrum issues has always been a reactive process for cable operators,” said Arthur Skinner, Vice President of Worldwide Sales for ZCorum. “Often they’re not aware they have an issue until a customer calls, and that’s when they then send a technician to the home with a hand-held meter to start a search for the problem.” SpectraVizion takes the guesswork out of problem identification and location by presenting on a simple dashboard a list of devices that are experiencing common downstream issues like Standing Waves, FM Noise, Suck-outs, Roll-off and Tilt. The tool leverages the spectrum data available from cable modems and set-top boxes that support full band capture, and advanced detection algorithms automatically identify devices experiencing downstream impairments. The operator can click on any device in the list to view a capture of the full spectrum from that day, or up to 30 days in the past.
