Test Error message Recommended action
26 V supply voltage is over/under
voltage
Replace the Power conversion board. If the problem persists, replace
the RF interface board. If the pr oblem persists, replace the power
supply. If the problem persists, send the instrument to a Tektronix
Service Center for repair.
9 V supply voltage is over/under
voltage
Replace the Power conversion board. If the problem persists, replace
the RF interface board. If the pr oblem persists, replace the power
supply. If the problem persists, send the instrument to a Tektronix
Service Center for repair.
6 V supply voltage is over/under
voltage
Replace the Power conversion board. If the problem persists, replace
the RF interface board. If the pr oblem persists, replace the power
supply. If the problem persists, send the instrument to a Tektronix
Service Center for repair.
5 V supply voltage is over/under
voltage
Replace the Power conversion board. If the problem persists, replace
the RF interface board. If the pr oblem persists, replace the power
supply. If the problem persists, send the instrument to a Tektronix
Service Center for repair.
3.3 V supply voltage is over/under
voltage
Replace the Power conversion board. If the problem persists, replace
the RF interface board. If the pr oblem persists, replace the power
supply. If the problem persists, send the instrument to a Tektronix
Service Center for repair.
ā9 V supply voltage is over/under
voltage
Replace the Power conversion board. If the problem persists, replace
the RF interface board. If the pr oblem persists, replace the power
supply. If the problem persists, send the instrument to a Tektronix
Service Center for repair.
L02 Voltage/Current
Test
L02 is over temp Warning only.
LO2 Phaselock
check
LO2 will not phase locked Send the instrument to a Tektronix Service Center for repair.
RF Converter ID
Test
Board not found. Run the PPC load test. This will rerun hardware discovery. If error
persists, send the instrument to a Tektronix Service Center for repair.
RF Converter FPGA
Load Test
FPGA Load failed. Send the instrument to a Tektronix Service Center for repair.
