the introduction of Adaptive NFE (firmware version A.18.00), the default state of
NFE was OFF for all Modes.
With the introduction of Adaptive NFE, the menu control is changed from On|Off to
Full|Adaptive|Off. For SCPI Backwards Compatibility, the existing SCPI command to
turn NFE on or off was retained, and a new command was added to set the state to
turn Adaptive On or Off:
–
[:SENSe]:CORRection:NOISe:FLOor ON|OFF|1|0 is retained, default
changed to On for modes that support Adaptive NFE
–
[:SENSe]:CORRection:NOISe:FLOor:ADAPtive ON|OFF|1|0 is added (for
certain Modes), default = On
–
FULL = :CORRection:NOISe:FLOor ON plus
:CORRection:NOISe:FLOor:ADAPtive ON
See "More Information" on page 290
Remote Command
[:SENSe]:CORRection:NOISe:FLOor ON | OFF | 1 | 0
[:SENSe]:CORRection:NOISe:FLOor?
Example
:CORR:NOIS:FLO ON
Dependencies Only appears in instruments with the NFE or NF2 license installed. In all others, does not appear, but
the SCPI command will be accepted without error but has no effect
Couplings When NFE is enabled in any mode manually, a prompt will be displayed reminding you to perform the
Characterize Noise Floor operation if it is needed. If NFE is enabled through SCPI and a Characterize
Noise Floor operation is needed, an error will be entered in the system error queue
Preset Unaffected by Mode Preset. Turned ON at startup and by Restore Mode Defaults in Modes that
support Adaptive. Turned OFF at startup and by Restore Mode Defaults in Modes that do not support
Adaptive
State Saved No
Remote Command
[:SENSe]:CORRection:NOISe:FLOor:ADAptive ON | OFF | 1 | 0
[:SENSe]:CORRection:NOISe:FLOor:ADAptive?
Example Turn NFE ON (Full mode):
:CORR:NOIS:FLO ON
Set to Adaptive:
:CORR:NOIS:FLO:ADAP ON
Dependencies Only available in Modes that support Adaptive NFE
Only appears in instruments with the NFE or NF2 license installed. In all others, the control does not
appear, but the SCPI command is accepted without error (but has no effect)
Couplings For backwards compatibility, sending :CORR:NOIS:FLO ON turns NFE Adaptive OFF. To turn
Adaptive ON, you must issue the commands in the proper order, as shown in the example above
