This subsystem provides commands that modify the display of data for the user. They do not modify the way in which data are returned to the controller.
Defines the mapping type. <mapping type> is the type of data that is being mapped. Note that RSSI, THD, SINAD, and External SINAD data will be stored, but only the selected mapping type will be used in the comparisons to determine the color of the points on the map. Mapping type must be one of the following values:
RSSI|THD|SINad|EXTS
The query version of this command returns “RSSI” if the mapping type is set to RSSI, “THD” if set to THD, “SIN” if set to SINAD, and “EXTS” if set to External SINAD.
Please note that this command only works when the current measurement is set to NBFM Coverage. Refer to the Related Command.

Description
This command returns the current active trace number in the format TRAC#.
Sets the IF bandwidth percent. This setting adjusts the Y-Axis scale for the Audio Spectrum and Audio Waveform graphs in the NBFM Analyzer measurement mode.
Sets the reference level scale value for the y-axis. In the NBFM Analyzer measurement, this value corresponds to the reference level on the spectrum graph type.
Note
Turning auto range on will automatically adjust the reference level. If auto range is on and this command is sent, the reference level will be set to the value until the next sweep. If auto range is off, the unit will keep the value until either auto range is turned back on, the reference level is changed, or a preset is activated.
Defines the graph type for the given trace <Tr>. <Tr> is the trace number in the range 1 to 4. If no trace number is specified, then the <Tr> parameter defaults to trace number 1. <Graph Type> is the graph type to which the specified trace is set, and it must be one of the following values:
SPECtrum|ASPEctrum|AWAVeform|SUMMary
The query version of this command returns “SPEC” if the specified trace graph type is set to Spectrum, “ASPE” if set to Audio Spectrum, “AWAV” if set to Audio Waveform, and “SUMM” if set to Summary.
Please note that this command only works when the current measurement is set to NBFM Analyzer. Refer to the Related Command below.
Selects the given trace, <Tr>, as the active trace. <Tr> is the trace number in the range 1 to 4 for NBFM Analyzer. If no trace number is specified, then the <Tr> parameter defaults to trace number 1.
