Abstract
A test device can be used with an Open Radio Access Network (O-RAN) fronthaul and to test an uplink communication channel for passive intermodulation distortion (PIM). The test device generates and transmits O-RAN compliant messages to request resource blocks (RBs) from an O-RAN radio unit (O-RU) installed at a cell site according to a delay time period. Based on the delay time period, the test device identifies the RBs for an uplink signal to be received by the O-RU on the uplink communication channel at a future time period. The test device requests the RBs and receives the RBs from the O-RU to test for PIM.
