RF:PRObe:PREAmp:MODe
Sets or returns the user-selected mode for an RF pre-amp connected to the RF
input - either
BYPass or AUTO.
Note that the actual status of the pre-amp (either
NONE, ON or BYPass)is
determined by the selected mode along with the RF reference level. You can query
the status of the pre-amp using the command RF:PRObe:PREAmp:STATus?

Related Commands
RF:PRObe:PREAmp:STATus?
Arguments
BYPass means the pre-amp will not amplify the signal. When the mode is set to
BYPass, the pre-amp amplification is always off, regardless of the RF reference
level.
AUTO means the pre-amp will turn its amplification on or off based on the RF
reference level. When the
MODe is set to AUTO and the RF reference level is below
the RF reference level threshold, then the pre-amp amplification is automatically
turned on, and the
STATus is set to ON. When the RF reference level is at or above
the RF reference level threshold, then the pre-amp amplification is automatically
turned off, and the
STATus is set to BYPass.
NOTE. The RF reference level threshold for the TPA-N-PRE model pre-amp is
-25 dBm on MDO4000/B/C models, and -15 dBm on MDO3000 models.
Examples
RF:PRObe:PREAmp:MODe BYP sets the preamp so that it will not amplify the
signal.
RF:PRObe:PREAmp:MODe? might return A UTO, indicating that the pre-amp
amplification has been set to turn on or off depending on whether the RF reference
level is above or below the RF reference level threshold.
