Notes
Preset and Max values are depending on Hardware Options (503, 507, 508, 513, 526)
Notes
Preset and Max values are dependent on Hardware Options (5xx)
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. It will once again be available, and show the previously set value, when you return to
the RF Input.
Dependencies
Span, RBW, Center frequency
If the electronic/soft attenuator is enabled, any attempt to change the value of the center frequency
>3.6 GHz by pressing the Up-arrow key, fails and results in an advisory message. If the equivalent
SCPI command is sent, this same message is generated as part of a “–221, Settings conflict”
warning.
Couplings
When auto-coupled in a non-zero span, the center frequency step size is set to 10% of the span.
When auto-coupled in zero span, the center frequency step size is set to the equivalent –3 dB RBW
value.
Preset

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
