What to do if there is LNA Current Fault on Comtech EF Data CSAT-5060?
- AAlexandra WebbAug 11, 2025
If the Comtech EF Data Transceiver LNA is connected correctly without any shorts, use the RMS Command to check the measured LNA current. If the LNA and cable are functional, disconnect the LNA and measure the voltage from the cable's center conductor to the shield using a DVM. A voltage of 12Vdc should be measured if the LNA Current Source is enabled (LCS=1). If the problem persists, it may indicate an issue with the CSAT LNA current source circuitry.
