VMIVME-7452 with a full-featured computer, coupled with a number of R & D personnel to develop the relevant hardware and software interfaces, in fact, can be very quickly designed a set of inexpensive, functional and practical, but also can be easily copied in large quantities of WLAN module testing equipment. System enhancements to the physical layer (PHY) wireless digital signal processing algorithms can be used to verify the performance of the system design of the physical layer (Tx PHY) at the transmitter side, or the quality of the relevant signal processing algorithms at the receiver side.

With the VMIVME-7452 data acquisition card, the most critical aspect will be in writing the associated signal processing programs, which is the expertise of R&D staff who understand the specifications, so it is usually a matter of time, not difficulty. Is it worth doing this or not? In the case of this article, the front-end conversion circuitry, for example, shouldn’t be too difficult for a slightly more experienced hardware engineer. The back-end real-time I-Q signal analysis program should be even easier for a Netcom operator. It does not take a long time, but in return, there is an opportunity to significantly reduce the production cost.

The VMIVME-7452 with VSG (Vector Signal Generator) can be used to evaluate the performance of transmitter-receiver (Tx-Rx) hardware design, and can also be provided to the production line to verify the performance of the product’s fundamental frequency. Of course, if the UP Converter and DOWN Converter circuits are added, it can be used as a real WLAN related product test bench.
