Common Measurement Functions
FREQ Channel
Freq Offset
Enables you to set a frequency offset value to account for frequency conversions outside of the analyzer.
This value is added to the display readout of the marker frequency, center frequency, start frequency, stop
frequency, and all other absolute frequency settings in the analyzer including frequency count. When a
frequency offset is entered, the value appears below the center of the graticule. To eliminate an offset,
perform a Mode Preset or set the frequency offset to 0 Hz.
See “More Information” on page 919.
Preset: Auto
ADEMOD: 1 MHz

State Saved: Saved in instrument state
Min: – (the maximum frequency of the instrument). That is, 27 GHz max freq
instrument has a CF step range of +/– 27 GHz. Note that this is the maximum
frequency given the current settings of the instrument, so in External Mixing,
for example, it is the maximum frequency of the current mixer band.
Max: The maximum frequency of the instrument. That is, 27 GHz max freq
instrument has a CF step range of +/– 27 GHz. Note that this is the maximum
frequency given the current settings of the instrument, so in External Mixing,
for example, it is the maximum frequency of the current mixer band.
Default Unit: Hz
Status Bits/OPC dependencies: non-overlapped
Initial S/W Revision: Prior to A.02.00
Modified at S/W Revision: A.03.00
Key Path:
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 907
State Saved: Saved in instrument state
