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.
:DISPlay[:WINDow]:TRACe:SELect?
Description
This command returns the current active trace number in the format TRAC#.
Sets the reference level scale value for the y-axis. In the P25 Analyzer measurement, this value corresponds to the reference level on the spectrum graph type.
Note
Turning auto range on automatically adjusts the reference level. If auto range is on and this command is sent, the reference level is set to the value until the next sweep. If auto range is off, the unit keeps the value until either auto range is turned back on, the reference level is changed, or a preset is activated.
Defines the mapping type. <mapping type> is the type of data that are being mapped. Note that RSSI, BER, and Mod Fid data are stored, but only the selected mapping type are used in the comparisons to determine the color of the points on the map. The parameter mapping type must be one of the following values:
RSSI|BER|MODFid
The query version of this command returns “RSSI” if the mapping type is set to RSSI, “BER” if set to BER, and “MODF” if set to Mod Fid.
Please note that this command only works when the current measurement is set to P25 Coverage. Refer to the Related Command below.
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:
The query version of this command returns “CONS” if the specified trace graph type is set to Constellation, “HIST” if set to Histogram, “SPEC” if set to Spectrum, “SUMM” if set to Summary, “EYED” if set to Eye Diagram, and “LINC” if set to linear constellation.
Please note that this command only works when the current measurement is set to P25 Analyzer.
Selects the given trace, <Tr>, as the active trace. <Tr> is the trace number in the range 1 to 4 for P25 Analyzer. If no trace number is specified, then the <Tr> parameter defaults to trace number 1.
