A hardware simulator reproduces the behavior of the radio propagation channel, thus making it possible to test "On table" the mobile radio equipments. The simulator can be used for LTE (Long Term Evolution) and WLAN (Wireless Local Area Network) 802.11ac applications, in indoor and outdoor environments. In this paper, the input signals parameters and the relative power of the impulse responses are related to the relative error and SNR of the output signals. After analyzing the influence of these parameters on the out-put error and SNR, an algorithm based on an Auto-Scale Factor (ASF) is analyzed in details to improve the precision of the output signals of the hardware simulator digital block architecture
