7.4.3 Sweep Mode
IM products in linear environment are frequency independent. Many passive
components show a frequency response that is less linear or strongly frequency
dependent. The sweep mode increments / decrements carrier signals by 1 MHz.
covering a Tx range that results in a sweep of the complete Rx frequency range.
Any deviations of PIM measurements that are frequency dependent are
immediately visible.
