Error -373634 generally occurs due to one of the following reasons:
- The Cabling connected to the RF Out Port of the VST is faulty and causing the signal reflections.
- The REF In port of the VST is receiving a signal which is has a significantly higher amplitude than the typical specification of the Port. For more details on this please refer to the specifications sheet of your VST.
- The output power specified for the signal is higher than the maximum power output of the VST.
- An external output source is connected to the RF Out port of the VST which is sending a signal into the RF Out port.
First, make sure that no external output source is connected to the RF port. Following this, check if the signal going to the REF In port and out of the RF Out port are within specification and try swapping the SMA Cable connected to the VST. If these steps don’t solve the issue, please contact NI Support
