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.
