125 kHz RFID tag reader uses FSK to reduce collisions ...

The RFID (radio-frequency identification) system consists of an RFID tag, a reader, and a user-interface computer. The passive RFID tag contains a silicon chip and an LC antenna circuit. The passive tag is energized by an RF field that's transmitted by the reader (interrogation). Therefore, the tag doesn't require any batteries for its operation.

ElectricPCB: Creating a RFID Reader From Scratch Part 2

The transmitter is a simple current amplifier, where the transistors Q1 and Q3 will alternately pull the antenna voltage high and low depending on the "control" signal in to the amplifier, thus forcing a high current through the antenna. The important thing to note is that this circuit does not generate any frequency signal on itself, it requires a source that produces the correct frequency, the...

RFID Block Diagram - University of Colorado Boulder

RFID Block Diagram

Shown above is a block diagram for one application of Radio Frequency Identification, or RFID. This particular application is a low-power, low-frequency (~125 kHz) tag reader for ID cards used at the Massachusetts Institute of Technology (MIT). As shown above, the block diagram consists of three main subsystems: a transceiver, a decoder, and a display module. The...

5m RFID Antenna Capture Mat | RFID Chip Timing | FinishLynx

The 5-meter RFID capture mat is a sturdy ground device that detects athlete RFID timing tags for lap, split, and finish timing. �The capture mat (also available in a 2.5 meter �size) connects with Lite or Elite Tag Readers to create a powerful and reliable RFID sports timing solution. Multiple mats can even be combined to create a single stitched mat to cover wide lanes and finish lines. �IPICO RFID detection mats are strong, weather-proof, and durable; they can be soaked, trampled, and even driven-over without affecting the antennas.

Product Data

Description

The IPICO antenna mats contain separate...

Can this also be used as a network analyzer to measure component bandwidth and amplifier?

A network analyzer can help the complex, or the vector, S parameter measurements. As I mentioned previously, a spectrum analyzer can only do scalar measurement, and the scalar measurement is the total results of the incident and the reflected waves. But if your application...

Can I do a Screen Shot with the USB port of GSP-830?

Yes, you can have a screen shot and save it in a USB flash through the USB port on the front panel of the GSP-830. The picture is saved in JPG format.

Do these have the ability to do S parameter or complex impedance for RF testing of components or systems?

With the Return Loss Bridge and the TG option, the GSP-830 can do scalar S11...
