It is recommended that the output of a signal source be verified with the use of a power
meter prior to connecting the source directly to the RF IN connector. Until you can
determine that the front-end attenuator is in the circuit (see the
R5750 Programmer's
Guide
), it is best to inject signals lower than 10 dBm. Additionally, any external signal
sources connected to RF IN must be turned on only after powering on the R5750 and
turned off prior to powering down the R5750.
2
The 10 MHz reference input must be powered down prior to powering down the R5750.
3
To set the R5750 to use the external 10 MHz reference, see the
SOURCE:REF:PLL
EXT
command (see the
ThinkRF R5750 Programmer’s Guide
).
