9.8.3 DUT TEST & LO TEST
Measure Input Frequency and Power:
When pressed the instrument will take a new
frequency counter and power meter reading for each channel. If errors relative to DUT
Frequency or Power are received, users should verify signal presence here.
If either channel DUT or LO reads
0.0Hz and below -10.0dBm
this indicates that there is no
signal present at the given input connector.
Users should check that the DUT is powered on, that all RF cables are good, and that the
copper coaxial jumper cables are installed on the front of the instrument. If signal still does not
appear to be present, check the signal on a spectrum analyzer.
