Universal Evaluation Kit
For Single Frequency FM Radio Modules
This Evaluation Kit can be used to evaluate single frequency Radiometrix VHF/UHF transmitter, receiver and transceiver modules. LED indicators are provided to show system status and to facilitate range testing and site surveys. The board is controlled by the Eval-RPC chip and incorporates several useful diagnostics & debug modes. Link-selectable 9.6kbps or 64kbps data rate.

Universal Evaluation Board

Features

  • Range Testing
  • Target Environment Testing
  • Noise and Interference Identification
  • Antenna Evaluation
  • TX1(H)/HX1/RX1, NTX2/NRX2, TX2(A)/TX2H/RX2(A), TX3A/RX3A, BiM1T/ BiM1R, CVR1, BiM/1/2/3A and NiM2 hardware test
  • Transient Analysis
  • Communication Eye Diagrm
  • Analogue and digital data transmission
  • Received Signal Strength Indicator (RSSI) meter
  • Linking external hardware directly or via on board Eval RPC
  • Responses up to 9.6kbps (A) or 64kbps (F)
The Eval-RPC is based upon a modified RPC-000-DIL design and provides management of all the necessary data and control lines. The user can define both operational mode and data bit rate simply by selecting the required positions on the provided DEBUG switch and the various jumpers. Indication of unit status is provided by means of LEDs for Power, Transmit, Receive, Carrier Detect, Signal and OK (link success) functions.
 
Check List

The Universal Evaluation Kit should include the following components and documentation:

  • 2 Analogue input/output boards
  • 2 Parallel port interface adaptor
  • 2 9V battery (PP3)
  • 2 1/4 wavelength whip for 418/433MHz, 869/914MHz and helical antennas for 173MHz
  • 2 10.24MHz crystals for 40kbps operation
  • 2 FRPC-000-DIL (optional)
  • 2 20.48MHz crystals for 160kbps operation (optional)

In addition to the above a 2-channel (or even better, a 4-channel) digital storage oscilloscope is highly recommended as a means of monitoring system operation.
