Output RF Spectrum Commands (Measure Subsystem)
FBIT
FBIT
Description Queries the position of the First (useful) BIT in time relative to when the Output RF
Spectrum measurement trigger occurred.
GPIB units are seconds (S), bit periods (T);
default unit is seconds (S).
Display units are US (micro-second), T (bit periods);
default unit is US (micro-second).
Syntax MEASure:ORFSpectrum:FBIT?
MEASure:ORFSpectrum:FBIT[:MM] | [:AVG]
Options Refer to Appendices D and F.
FMERrors
Description FM ERrors query returns the number of FM demodulated bits different from the best bit
match (of the demodulated burst bits) to the selected midamble before differential decoding
for ORFS[:POWer] measurement. This only valid for MSYN:SYNC:MODE
’MIDAMBLE’.
Syntax MEASure:ORFSpectrum:FMERrors?
Options Not Applicable.
MARKer:LEVel
Description Queries the MARKer LEVel which is relative amplitude data. This value is a function of
the marker position set or queried by ORFSpectrum:MARKer:POSition. Default unit is dB
relative to the average power over the useful bits in the measured burst when ORFS:FREQ
was set to zero.
GPIB unit is dB.
Display unit is dB.
Syntax MEASure:ORFSpectrum:MARKer:LEVel?]
MEASure:ORFSpectrum:MARKer:LEVel[:MM] | [:AVG]
Options Refer to Appendices D and F.
