3.6.6 Frequency

Opens the Frequency menu, which contains controls that allow you to control the

frequency and channel parameters of the instrument.

Some features in this menu are the same for all measurements in the current Mode

– they do not change as you change measurements. Settings like these are called

“Meas Global” and are unaffected by Meas Preset. For example, Center Frequency is

the same for all measurements — it does not change as you change measurements.

3.6.6.1 Settings

Contains controls that pertain to the X-Axis parameters of the measurement. These

parameters control how data on the vertical (X) axis is displayed and control

instrument settings that affect the horizontal axis.

Center Frequency

Sets the frequency that corresponds to the horizontal center of the graticule. While

adjusting Center Frequency, Span is held constant.

The Center Frequency setting is the same for all measurements within a mode, that

is, it is Meas Global. Some Modes are also able to share a Mode Global center

frequency value. If this is the case, the Mode will have a Global tab in its Meas Setup

menu.

Center Frequency sets (and queries) the center frequency for the currently selected

input. If your instrument has multiple inputs, and you select another input, Center

Frequency changes to the value for that input. SCPI commands are available to

directly set the center frequency for a specific input.

Center Frequency is remembered as you go from input to input. Thus, you can set a

Center Frequency of 10GHz with the RF Input selected, change to BBIQ and set a

Center Frequency of 20MHz, then switch to External Mixing and set a Center Freq

of 60GHz, and when you go back to the RF Input, Center Frequency will go back to

10GHz; back to BBIQ and it is 20MHz; back to External Mixing and it is 60GHz.
