6 RLC Swept SA Measurement Front-Panel & SCPI Reference
FREQ Channel
Scope Meas Global
Remote Command [:SENSe]:FREQuency:OFFSet <freq>
[:SENSe]:FREQuency:OFFSet?
Example FREQ:OFFS 10 MHz
Notes
Preset and Max values are dependent on Hardware Options (503, 507, 508, 513, 526)
Dependencies Freq Offset is not available in External Mixing. In this case the Freq Offset key is grayed out and
shows a value of zero. However, the value of CF Offset that was set for the RF Input is retained
and restored when the user switches back to the RF Input.
Preset See the table in See "Center Frequency Presets" on page 574

Compatibility SCPI DISPlay:WINDow[1]:TRACe:X[:SCALe]:OFFSet
The DISPlay version of the command is in the instrument for compatibility across platforms and
is not recommended for new development.
Backwards Compatibility
Notes 1. In pre-X-Series instruments, Frequency Offset could not be adjusted by the knob or step keys.
That is no longer the case.
2. Some previous spectrum analyzers did not adjust frequency counter results for the Frequency
Offset. The X-Series does adjust the frequency counter for the offset.

More Information
This command does not affect any bandwidths or the settings of relative frequency parameters
such as delta markers or span. It does not affect the current hardware settings of the analyzer,
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
