Sensitivity Commands

For Stepped measurement modes only
Sets/Gets the DynamicDriftReduction 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.
Property Value
Boolean = True if enabled
VB.NET Syntax
If(odaClient.Sensitivity.DynamicDriftReduction = False) Then
odaClient.Sensitivity.DynamicDriftReduction = True
End If
VB 6.0 Syntax
If(odaClient.Sensitivity.DynamicDriftReduction = False) Then
odaClient.Sensitivity.DynamicDriftReduction = 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.
