3 Short-Range Comms & IoT Mode
3.4 HRP UWB Demodulation Measurement
Couplings When auto-coupled in a non-zero span, the center frequency step size is set to 10% of Span. When
auto-coupled in zero span, the center frequency step size is set to the equivalent -3 dB RBW value
Preset
AUTO
State Saved Saved in instrument state
Min/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
