Frequency Response Correction
The
Response
setup menu shown below allows frequency dependent gain or loss offsets to be entered as part of the
measurement setup.
Response
is a frequency sensitive offset so as you change the measurement frequency the
response changes accordingly.
Response
amplitude is always expressed in dB and the frequency is expressed in Hz.
The interpolation is linear with respect to frequency and dB. The
Response
setup allows up to 201 points to be
entered. The response points are frequency and amplitude pairs. Setting the response is independent of enabling or
disabling the feature. The toolbar button turns correction on or off.
Click
Setup
and enter the frequency and corresponding offset in the table shown below. Click
Add
after each
frequency and offset entry to build the table. Select
Show Graph
to get a graphical presentation of the frequency
offsets that were entered in the table.
