Table 5-1: Center frequency bands
2.4 GHz < f < 2.45 GHz (no CISPR band)
set f to 2.4 GHz - Span / 2 (next valid band below
the gap)
2.45 GHz <= f < 2.5 GHz (no CISPR band)
set f to 2.5 GHz + Span / 2 (next valid band above
the gap)
5.725 GHz < f < 5.8 GHz (no CISPR band)
set f to 5.725 GHz - Span / 2 (next valid band below
the gap)
5.8 GHz <= f < 5.875 GHz (no CISPR band)
set f to 5.875 GHz + Span / 2 (next valid band
above the gap)
Remote command:
Center Frequency Stepsize
Defines the step size by which the center frequency is increased or decreased using
the arrow keys.
When you use the rotary knob the center frequency changes in steps of only 1/10 of
the span.
The step size can be coupled to another value or it can be manually set to a fixed
value.
"Manual"
Defines a fixed step size for the center frequency. Enter the step size
in the "Value" field.
Remote command:
Frequency Offset
Shifts the displayed frequency range along the x-axis by the defined offset.
This parameter has no effect on the instrument's hardware, on the captured data, or on
data processing. It is simply a manipulation of the final results in which absolute fre-
quency values are displayed. Thus, the x-axis of a spectrum display is shifted by a
constant offset if it shows absolute frequencies. However, if it shows frequencies rela-
tive to the signal's center frequency, it is not shifted.
A frequency offset can be used to correct the display of a signal that is slightly distorted
by the measurement setup, for example.
The allowed values range from -1 THz to 1 THz. The default setting is 0 Hz.
Remote command:
Tuned Frequency
Defines the currently selected measurement frequency as a positive or negative devia-
tion from the selected center frequency. The Tuned Frequency line can also be moved
by drag and drop. By default, the Tuned Frequency is equal to the Center Frequency
when the Multi CISPR APD application is started.
