The Huntron Access RF system provides reliable and repeatable near field measurements of RF signals. The system integrates a Huntron Access 2 Prober, a spectrum analyzer and Langer RF near field probes under the control of Huntron Workstation. This combination delivers an automated method to place a “sniffer probe” precisely where it is needed.

In a typical application, single point measurements in RF circuits are dependent on the manual dexterity and interpretation of the operator. The position of the RF probes must be duplicated to achieve repeatable measurements. The Huntron Access RF eliminates errors in probe placement and the need for documentation that identifies the physical location of the probe points. When measuring points on your circuit board assembly (CCA), the Huntron Access RF will provide a minimum 10:1 improvement in probing time over manual methods.

Testing with the Access RF system requires the CCA under test to be powered and in a functional state so measurements can be taken. The end user provides the PC, power supplies and control hardware based on their knowledge of the CCA and the measurements that need to be captured. The size of the Access RF provides plenty of space to allow for cabling and connections to be made to the CCA. The Prober has a base plate cover that can be removed to allow for easy access to the probing area from below.

Huntron Workstation software is used to create a test plan where each test position is a X, Y and Z location or Virtual Test Point (VTP). When the CCA is scanned the Access RF Prober precisely places the RF probe at each VTP capturing a non-contact, non-invasive measurement. Power and spectrum measurements from known good boards are saved using Workstation software for comparison when unknown CCAs are scanned. Deviation from stored measurements indicate areas of concern that can be investigated further. The Access RF system makes the process much easier through software and hardware automation

• Replace manual “sniffer probe” testing with automated Virtual Test Points
• A significant decrease in test times when compared to manual methods
• More accurate measurements resulting from repeatable RF probe placement
• More effective use of valuable technical and engineering resources
• Handle turnover more effectively by retaining test knowledge in-house
