Notes
In pre-X-Series instruments, Freq Offset could not be adjusted by the knob or step keys. That is no
longer the case
More Information
This command does not affect any bandwidths, nor the settings of relative
frequency parameters such as delta markers or span. It does not affect the current
hardware settings of the instrument, but only the displayed frequency values.
Entering an offset does not affect the trace position or display, just the value of the
start and stop frequency and the values represented by the trace data. The
frequency values of exported trace data, queried trace data, markers, trace data
used in calculations such as N dB points, trace math, etc., are all affected by Freq
Offset. Changing the offset, even on a trace that is not updating, immediately
changes all the above, without taking new data
3.10.7 Marker
There is no Marker functionality in this measurement.
3.10.8 Meas Setup
Accesses a menu panel that allows averaging control, and enables zero-span
measurements for increased accuracy.
3.10.8.1 Settings
Contains frequently used Meas Setup functions to which you will want the fastest
access.
