DriftCorrection Property
IFBandwidth Property
264
For Stepped measurement modes and polarization resolved Swept
measurement modes only
Sets/Gets the DriftCorrection value. This system function
reduces measurement error contributed by gradual, ambient
temperature changes that change the response of the DUT or the
measurement system itself. It is appropriate for use when the
temperature of the room is gradually rising or falling, or when
the test device gradually transitions from one temperature to
another. This function is not suited to rapid or stepped
temperature changes. The movement of air over the test path
can generate rapid, small group delay changes. Reduce this type
of error by covering the test path to block air currents. Turning
this function on will approximately double your test time for
stepped measurements.
Property Value
Boolean = True if enabled
VB.NET Syntax
If(pdlaClient.Sensitivity.DriftCorrection = False) Then
pdlaClient.Sensitivity.DriftCorrection = True
End If
VB 6.0 Syntax
If(pdlaClient.Sensitivity.DriftCorrection = False) Then
pdlaClient.Sensitivity.DriftCorrection = True
End If
Sets the bandwidth of the filtering process that trades off
measurement noise floor (sensitivity) against measurement
speed. A lower IF bandwidth value means lower noise (high
sensitivity) and a longer measurement time. Reduce the IF
bandwidth as needed to control trace noise. This is particularly
important when measuring a high insertion loss device.
