3 WLAN Mode
3.2 Channel Power Measurement
If the knob or step keys are being used, depends on the value of the other three interdependent
parameters Center Frequency, Start Frequency, Stop Frequency
Annunciation Data out of range, value clipped to upper limit
Annotation Span <value> appears on the first line of the annotation in the lower right corner of display
LTE, 5G NR Modes only:
Remote Command
[:SENSe]:CHPower:FREQuency:SPAN:AUTO ON | OFF | 1 | 0
[:SENSe]:CHPower:FREQuency:SPAN:AUTO?
Example
:CHP:FREQ:SPAN:AUTO OFF
:CHP:FREQ:SPAN:AUTO?
Notes The span value is adjusted when the relevant carrier parameters such as bandwidth, integration
bandwidth, number of component carriers etc., are changed, whatever the span state (Auto or Man)
When in Man state, if the input value is less than the required sum of total integration bandwidths and
gaps of the multi-carriers, the required span value is set
Dependencies Only available in LTE/LTE-Advanced FDD/TDD Modes and 5G NR Mode, CHP measurement
