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.

[<Q port probe id>]
This is reporting the type of probe sensed on the Q port. There is no parameter for overriding what is
sensed.

Set the attenuation for the current I probe to 100.00:1.

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.
Each probe type has its own default. The default for the "Unknown" probe type is 1:1.
Saved with probe calibration data. It survives a power cycle and is not affected by a Preset or
Restore.
