SETup:SMONitor

Function

This command sets the scale of the spectrum monitor's display in dB per division (dB/div).

Range: 0.1 to 20 dB

Resolution: 0.1

Range: 0.1 to 20 dBResolution: 0.1

10 dB

Programming Example

 
OUTPUT 714;"SETup:SMONitor:AMPLitude:PDIVision 1DB" 

 
!Sets scale of the spectrum monitor's display to 1 dB per division.

Function

This command allows you to set whether or not the spectrum monitor's reference level is selected automatically by the test set.

Range: 1|ON|0|OFF

Query

Range: 1|0

OFF

Programming Example

 
OUTPUT 714;"SETup:SMONitor:AMPLitude:RLEVel:AUTO ON" 

 
!Sets spectrum monitor's reference level to set automatically.

Function

This command allows you to set the spectrum monitors actual reference level in dBm. The range settings are coupled to the amplitude offset value for the current value of the expected frequency (set using SYSTem:CORRection:[:SGAin] ). Changing the amplitude offset value does not change the reference value, unless the new value for the amplitude offset forces the current value of the reference level to exceed the range limits. If this happens the reference level is set to its limit.

Range: (-50 dBm + Amplitude Offset) to +37 dBm

Resolution: 0.1 dB

Query

Range: (-50 dBm + Amplitude Offset) to +37 dBmResolution: 0.1 dB

+37 dB + Amplitude Offset

Programming Example

 
OUTPUT 714;"SETup:SMONitor:AMPLitude:RLEVel:MANual -20DBM" 

 
!Sets spectrum monitor's reference level to -20 dBm.

Function

This command queries the resolution bandwidth being used by the spectrum monitor measurement. It is returned in the unit of Hz.

Query

Range: 1 kHz to 5MHz

Programming Example

 
OUTPUT 714;"SETup:SMONitor:BAND?" 

 
!Returns spectrum monitor's resolution bandwidth.

Function

This command sets/queries the Spectrum Monitor Resolution Bandwidth Coupling State. When the state of this parameter is ON the Resolution Bandwidth is determined by the Frequency Span setting ( SETup:SMONitor:FREQuency:SPAN ). When this parameter is set to OFF the Frequency Span and the Resolution Bandwidth parameters are decoupled and can be set separately to any valid Frequency Span and Resolution Bandwidth. See Resolution Bandwidth and Frequency Span for the complete list of valid settings for Frequency Span and Resolution Bandwidth.

The command to set the Frequency Span is SETup:SMONitor:FREQuency:SPAN

The command to set the resolution bandwidth is SETup:SMONitor:BANDwidth|BWIDth:MANual .

Requirements

Test Application Revision:B.09 and above

Lab Application Revision: A.01 and above

Setting

Range: 1|ON|0|OFF

Query

Range: 1|0

Programming Example

 
OUTPUT 714;"SETup:SMONitor:BAND:AUTO 0" 

 
!Turns Spectrum Monitor Resolution Bandwidth Coupling parameter OFF.

Function

This command sets/queries the value of the resolution bandwidth when SETup:SMONitor:BANDwidth|BWIDth:AUTO is set to OFF. When SETup:SMONitor:BANDwidth|BWIDth:AUTO is set to ON, the resolution bandwidth is determined by the Frequency Span setting ( SETup:SMONitor:FREQuency:SPAN ) and can be queried using the SETup:SMONitor:BANDwidth|BWIDth[:RESolution]? command.

When using this command the values in the Frequency Span and Resolution Bandwidth columns of Resolution Bandwidth and Frequency Span are no longer coupled. Therefore, the Frequency Span and the Resolution Bandwidth parameters can be set to any value in the Frequency Span and Resolution Bandwidth columns, respectively.

This command also sets the Spectrum Monitor Reference Level Coupling State to OFF (see SETup:SMONitor:AMPLitude:RLEVel:AUTO ).

The units (HZ|KHZ|MHZ) are optional, if no units are specified then the default is HZ.

Requirements

Test Application Revision: B.09 and above
Lab Application Revision: A.01 and above

Setting

Range: A value in the range 300 Hz to 5 MHz can be entered, however the value is rounded to a valid entry. The decision point for rounding up or down is the halfway point between the first valid entry below the setting and the first valid entry above the setting. The valid entries include: 300 Hz, 1 kHz, 3 kHz, 10 kHz, 30 kHz, 100 kHz, 300 kHz, 1 MHz, 5 MHz.

Query

300 Hz, 1 kHz, 3 kHz, 10 kHz, 30 kHz, 100 kHz, 300 kHz, 1 MHz, 5 MHz.

Programming Example

 
OUTPUT 714;"SETup:SMONitor:BANDwidth:MANual 600 khz" 

 
!Sets the Resolution Bandwidth to 300 kHz because the first valid entry below the setting is 300 kHz !and the first valid entry above the setting is 1 MHz. The middle point between the two valid values is !650 kHz and since 600 kHz is below 650 kHz, the test set rounds 600 kHz to 300 kHz. 

Function

This command sets/queries the resolution bandwidth when the spectrum monitor is operating in zero span mode. To change the spectrum monitor to zero span mode, use the command SETup:SMONitor:FREQuency:SPAN , to set the frequency span to 0 Hz.

To measure the total power of a signal you must select a resolution bandwidth greater than or equal to the signal bandwidth. To resolve two spectral components the resolution bandwidth must be less than the difference between them.

The units (HZ|KHZ|MHZ) are optional, if no units are specified then the default is HZ.

Any setting you enter is rounded to the nearest of the three settings.

Range: 100 kHz|300 kHz|1 MHz

Query

Range: 100 kHz|300 kHz|1 MHz

Programming Example

 
OUTPUT 714;"SETup:SMONitor:BAND:ZSPan 100 KHZ" 

 
!Sets spectrum monitor's zero span resolution bandwidth to 100 kHz.

Function

This command arms triggering for a measurement sweep. Trigger arming can be single (OFF) or continuous (ON). With single triggering, the measurement sweep starts when an INITiate or READ command is received. With continuous triggering, measurement sweeps initiate immediately and continuously.

The *RST (remote full preset) default setting is single triggering. At power-on or after a front-panel preset, the default setting is continuous triggering.

Function

This command sets/queries the trace update parameter.

• MAXHold (maximum hold) maintains the maximum level for each trace point of the selected trace and updates each trace point if a new maximum level is detected in successive sweeps.
• MINHold (minimum hold) maintains the minimum level for each trace point of the selected trace and updates each trace point if a new minimum level is detected in successive sweeps.

Range: IMM|PROT|RISE|EXT

Programming Example

 
OUTPUT 714;"SETup:SMONitor:TRIGger:SOURce RISE" 
! Sets the measurement to trigger on the rising edge of an RF burst.
