The Aaronia AG AR 122/029 Tektronix RSA Spectrum Analyzer option allows the usage and configuration of any separate Tektronix RSA USB Analyzer. It extends the real-time bandwidth of your Tektronix RSA from 40MHz to 44MHz or even 52MHz. Moreover, it supports device stitching: Use multiple Tektronix RSA units to expand the real-time bandwidth or to monitor different frequency bands at the same time. In order to use this block, the serial number of your Tektronix spectrum analyzer is required. You can forward this to us after ordering by telephone or by e-mail, stating the order number.
