Input/Output
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.
Key Path Input/Output, I/Q, I Setup | Q Setup, I Probe | Q Probe
Remote Command [:SENSe]:CORRection:IQ:I|Q:ATTenuation:RATio <real>
[: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.
