status. The calibration data is stored permanently (survives a power cycle) and is not affected by
a Preset or any of the Restore commands. When the probe has EEPROM identification (most
newer Agilent probes have this), the calibration data is stored by probe serial number and port,
so if you have two probes of the same type, the correct calibration data will be used for each. For
probes that do not have EEPROM identification, the calibration data is stored by probe type and
port and the instrument cannot distinguish between different probes of the same type. In all cases
(with or without EEPROM identification), the calibration data is port specific, so it will not follow
a specific probe from port to port if the probe is moved.
The "Unknown" probe type is used whenever no probe is sensed. When no calibration data exists
for "Unknown" the latest cable calibration data is used (see Section
).
Attenuation
The attenuation is part of the calibration data stored with the probe type and is initially the
value that was returned by the last calibration. You can modify this value and any changes will
be stored with the calibration data and will survive power cycles and presets. When a probe
calibration is performed the attenuation value will be overwritten by the calibration.

Remote Command
[:SENSe]:CORRection:IQ:I|Q:ATTenuation:RATio
[:SENSe]:CORRection:IQ:I|Q:ATTenuation:RATio?
Example
Set the attenuation for the current I probe to 100.00:1.
CORR:IQ:I:ATT:RAT 100
Notes
Each probe type has its own attenuation setting. As probes are changed the attenuation value
will reflect the new probe's setting. Changing the attenuation affects only the current probe
type's setting and leaves all others unchanged.
When the IQ Path is I+jQ, the Q probe attenuation setting must match the I Probe attenuation
setting within 1 dB. If this is not the case, an error condition message is generated, 159;Settings
Alert;I/Q mismatch:Attenuation.
Preset
Each probe type has its own default. The default for the "Unknown" probe type is 1:1.
State Saved
Saved with probe calibration data. It survives a power cycle and is not affected by a Preset or
Restore.
