Keysight x-series Instruction Manual

3 Short-Range Comms & IoT Mode
3.3 LoRa (CSS) Demodulation Measurement
Remote
Command
[:SENSe]:LORA:BANDwidth[:RESolution] <bandwidth>
[:SENSe]:LORA:BANDwidth[:RESolution]?
Example
:LORA:BAND 5.1 kHz
:LORA:BAND?
Notes Only certain discrete resolution bandwidths are available. For numeric entries, all RBW Types choose
the nearest (arithmetically, on a linear scale, rounding up) available RBW to the value entered
Couplings
When the RF resolution bandwidth is set to auto, the resolution bandwidth is automatically calculated
according to the span with an approximate ratio of span/RBW being 106:1. The value should not exceed
3 MHz
Preset 680 Hz
State Saved Saved in instrument state
Min 1 Hz
Max 8 MHz
Annotation A “#” mark appears before “RF Res BW” in the annotation when it is switched from Auto to Manual
coupling
RF Res BW Auto
Remote Command
[:SENSe]:LORA:BANDwidth[:RESolution]:AUTO ON | OFF | 1 | 0
[:SENSe]:LORA:BANDwidth[:RESolution]:AUTO?
Example
:LORA:BAND:AUTO ON
:LORA:BAND:AUTO?
Preset
AUTO
Channel BW
Indicates the bandwidth of the demodulation. The shape of the filter is Flattop.
Remote Command
[:SENSe]:LORA:BANDwidth:CHANnel <freq>
[:SENSe]:LORA:BANDwidth:CHANnel?
Example
:LORA:BAND:CHAN 200 kHz
:LORA:BAND:CHAN?
Dependencies The maximum value of the channel BW depends on the maximum IF BW available on the instrument
and must not exceed 160 MHz
Couplings The acquisition time is coupled to the channel BW. As the channel BW changes, the acquisition time is
changed as well to maintain the amplitude calibration
