General Information : TD-LTE Commands : [:SENSe] Subsystem

[:SENSe] Subsystem
The commands in this subsystem relate to device-specific parameters, not signal-oriented parameters.
[:SENSe]:BANDWidth[:RESolution] 1.4|3|5|10|15|20
[:SENSe]:BANDWidth[:RESolution]?
Title
Bandwidth
Description
Sets the channel bandwidth. 15 MHz and 20 MHz are only available if Option 543 is installed.
Parameter
1.4|3|5|10|15|20
Parameter Type
<char>
Default Value
The default bandwidth is 10 MHz.

[:SENSe]:EVM:MODe AUTO|PBCHonly
[:SENSe]:EVM:MODe?
Title
Set EVM Mode
Description
Sets/Returns the EVM Mode to either Auto or PBCH Only.
Parameter
AUTO|PBCHonly
Parameter Type
<char>
Default Value
AUTO

[:SENSe]:FREQuency:CENTer <freq>
[:SENSe]:FREQuency:CENTer?
Title
Center Frequency
Description
Sets the center frequency.
Parameter
<freq>
Default Value
1 GHz
Default Unit
Hz
Range
10 MHz to 4 GHz

Freq, Center Freq
[:SENSe]:FREQuency:SIGStandard:CHANnel <number>
[:SENSe]:FREQuency:SIGStandard:CHANnel?
Title
Channel Selection
Description
Sets the channel number for the selected signal standard.
Parameter
<number>
Front Panel Access
Frequency, Channel
[:SENSe]:FREQuency:SIGStandard:NAMe [String]
[:SENSe]:FREQuency:SIGStandard:NAMe?
Title
Signal Standard
Description
Selects the desired signal standard from the list. The <string> argument is the name
of the desired signal standard as displayed in the instrument’s current signal standard list. The list can be seen on the instrument by choosing the Signal Standard submenu button in the Freq menu. The list can also be downloaded remotely and viewed using Anritsu Master Software Tools. For example, if the desired Signal Standard is
P-GSM 900 - Uplink, then the value of the <string> argument would be
“P-GSM 900 - Uplink”.
The query form of this command will return the name of the currently selected Signal Standard from the list.
Parameter
<string>

[:SENSe]:POWer[:RF]:RANGe[:IMMediate]
Title
Amplitude Range
Description
Re-calculates amplitude range. Note that issuing this command will set the automatic dynamic range OFF.

[:SENSe]:POWer[:RF]:RANGe:AUTO
Front Panel Access
Amplitude, Adjust Range
[:SENSe]:POWer[:RF]:RANGe:AUTO {Boolean (default=1 [ON])}
[:SENSe]:POWer[:RF]:RANGe:AUTO?
Title
Automatic Amplitude Range
Description
Sets the automatic amplitude range. Setting the value to ON or 1 will result in the amplitude range being coupled to the detected input signal level. Setting the value to OFF or 0 will result in the input attenuation being un-coupled from the input signal level. That is, changing the input signal level will not change the amplitude range.
When this command is issued, the amplitude range itself will not change. The default value is ON. That is, sending :SENS:POW:RANG:AUTO is equivalent to sending :SENS:POW:RANG:AUTO ON.
Parameter
OFF|ON|0|1
Parameter Type
<boolean>
Default Value
ON

Amplitude, Auto Range
[:SENSe]:RF:SPECtrum:SPAN Auto|1.4|3|5|10|15|20|30
[:SENSe]:RF:SPECtrum:SPAN?
Title
Automatic Amplitude Range
Description
Sets the span for the Spectrum view. For example, setting the value to 5 will set the span for the Spectrum view to 5 MHz and setting the value to 20 will set the span for the Spectrum view to 20 MHz.
Parameter
Auto|1.4|3|5|10|15|20|30
Default Value
Auto
Default Unit
MHz

[:SENSe]:SUBFrame <Sub-frame number 0-9>
[:SENSe]:SUBFrame?
Title
Set Sub-Frame Number
Description
Sets/returns the sub-frame number. The sub-frame number is used in Power vs. Time to zoom in the trace data to a particular sub-frame.
Parameter
0-9
Parameter Type
<char>
Default Value
0
Front Panel Access
Measurement, RF, Power vs. Time, View (Sub-Frame), Sub-Frame Number
[:SENSe]:TRIGger NOTRIGger|EXTernal
[:SENSe]:TRIGger?
Title
External Trigger
Description
Sets the external trigger. The query form returns either “NOTRIG” or “EXT” in Ascii (without the double quotes).
Default Value
No Trig
