With our BIS V evaluation unit, you can use up to four read/write heads per evaluation unit simultaneously. Its frequency independence enables mixed operation of all frequencies (BIS M, BIS L, BIS C, BIS U). This means that only one type of evaluation unit needs to be kept in stock, which greatly simplifies storage. For industry-independent use, the evaluation unit is also available with all bus systems commonly used worldwide.
