Trigger 34 Description

Sequence: C11
Trigger 34 (STV Baseline Common Mode Rejection Test Mode 2)
While monitoring the instrument in Fast Basic mode, commands are sent to the HFR to turn off the antenna input to receivers, and turn on the internal calibration (random noise) to both the plus side inputs and the minus side inputs and the EW inputs. A random noise signal shows up on the MFR, WFR, and WBR. The receivers configured for dipole input receive an attenuated signal, because of the common mode rejection of the diff amp.
