For more information, tap a topic. Included in this section are also topics for several front panel keys not described in other topics.
Page 86 2.1 Screen Tabs 2.1 Screen Tabs In the X-Series Multitouch User Interface (or Multitouch UI), you can run many different Measurement Applications, or “Modes”. Examples are Spectrum Analyzer Mode, LTE-A FDD Mode, IQ Analyzer Mode, and Real Time Spectrum Analyzer Mode.
Page 87 2 User Interface 2.1 Screen Tabs The following topics provide more information: – "Mode/Meas/View Dialog" on page 87 – "Add Screen" on page 104 – "Multiscreen" on page 174 2.1.1 Mode/Meas/View Dialog The Mode/Meas/View dialog opens when you press the selected (blue) Screen tab (see "Screen Tabs"...
Page 88 2 User Interface 2.1 Screen Tabs 2.1.1.1 Mode The first column in the Mode/Meas/View dialog allows you to select the desired Mode from those currently licensed in your instrument. Modes, also known as “measurement applications”, are collections of measurement capabilities packaged together to provide you with an instrument personality specific to your measurement needs.

See "Mode and Measurement Select" on page :INSTrument[:SELect] <mode_id> Remote Command where <mode_id> is one of the values listed in "Index to Modes" on page 90 below :INSTrument[:SELect]? :INST SA Example :INST:CAT? Notes...
Page 90 2 User Interface 2.1 Screen Tabs :CONF commands Index to Modes The Mode Number in the table below is the parameter for use with the :INSTrument:NSELect command. The Mode Parameter is the parameter for use with the :INSTrument[:SELect] command. Your actual choices will depend upon which applications are installed in your instrument.
Page 91 Each application (Mode) that runs in an X-Series instrument consumes virtual memory. The various applications consume varying amounts of virtual memory, and as more applications run, the memory consumption increases. Keysight characterizes each Mode and assigns a memory usage quantity based on a conservative estimate.
Page 92 Notes "BASIC","GSM","EDGEGSM","CDMA","SERVICE" X-Series uses the ESA/PSA compatible query of a string contain comma separated values: "SA,PNOISE,NFIG,BASIC" Current Application Model (Remote Command Only) Returns a string that is the Model Number of the currently selected application (mode).
Page 93 2 User Interface 2.1 Screen Tabs Current Application Options (Remote Command Only) Returns a string that is the Options list of the currently selected application (Mode). This information is also displayed in the Show System screen :SYSTem:APPLication[:CURRent]:OPTion? Remote Command :SYST:APPL:OPT? Example Notes Query returns a quoted string that is the Option list of the currently selected application (Mode).
Page 94 2 User Interface 2.1 Screen Tabs Application Catalog Revision (Remote Command Only) Returns the Revision of the provided Model Number. :SYSTem:APPLication:CATalog:REVision? <model> Remote Command :SYST:APPL:CAT:REV? ‘N9060A’ Example Notes Returned value is a quoted string of revision for the provided Model Number. The revision will be a null- string ("") if the provided Model Number is not installed, licensed, and loaded.
Page 95 2 User Interface 2.1 Screen Tabs GSM Mode compatibility command (Remote Command only) Provided for backwards compatibility. When this command is received, the analyzer aliases it to the following: :INST:SEL EDGEGSM :INSTrument[:SELect] GSM Remote Command :INST GSM Example SA compatibility command for EMC (Remote Command only) Provided for ESU compatibility.
Page 96 2 User Interface 2.1 Screen Tabs This results in the analyzer being placed in the EMI Receiver Mode, running the APD measurement, in order to emulate the ESU APD Mode. :INSTrument[:SELect] APDistribution Remote Command :INST APD Example IF Mode compatibility command for EMC (Remote Command only) Provided for ESU compatibility.

Page 106 2 User Interface 2.2 Meas Bar 2.2 Meas Bar The Meas Bar is used to display annotation for the current measurement. There are three primary uses for the Meas Bar: 1. To show annotation for the most important parameters in the measurement so you can see them at a glance 2.
Page 107 2 User Interface 2.2 Meas Bar Settings that are colored amber are those that you need to be particularly aware of; for example, if Alignments are off, this is shown in amber, so you will know that you may not be meeting spec. Similarly, if DC coupling is on, this is shown amber, to alert you to be careful what voltage you put on the input.
Page 108 2 User Interface 2.2 Meas Bar LXI indicator This indicator displays in green when LAN is connected, in white when LAN is not connected, and in red when LAN is connected but has a connection problem. PASS/FAIL indicator This annunciator displays when Limits are turned on. It is green if all Limits are passing, and a red FAIL if any limit is not passing.

Page 982 3 Short-Range Comms & IoT Mode 3.7 ACP Measurement sweep is equivalent to a single measurement. A single sweep is taken after the trigger condition is met; and the instrument stops sweeping once that sweep has completed. However, with Average/Hold Num >1, and at least one trace set to Trace Average, Max Hold, or Min Hold, or a Waterfall window being displayed, multiple sweeps/data acquisitions are taken for a single measurement.
Page 983 3 Short-Range Comms & IoT Mode 3.7 ACP Measurement Averaging The weighting factor used for averaging is k. This is also the average/hold count for how many valid sweeps (data acquisitions) have been done. This is used for comparisons with N, as those comparisons always needs to be based on valid completed sweeps.

Page 985 3 Short-Range Comms & IoT Mode 3.7 ACP Measurement instrument amplitude accuracy specifications only apply when Auto Sweep Time is set to ACCuracy. Additional amplitude errors that occur when Auto Sweep Time is set to NORMal usually well under 0.1 dB, though this is not guaranteed. Because of the faster sweep times and still low errors, NORMal is the preferred setting of Auto Sweep...
Page 986 3 Short-Range Comms & IoT Mode 3.7 ACP Measurement Cont, a new trace is taken. If any trace is in average or hold, the averaging starts over. Because of sweep time quantization issues, the knob and up/down keys cannot be used to adjust the number of points.

Page 989 View and Blank. Averaging was global to all traces and was controlled under the BW/Avg menu. In X-Series, trace averaging can be done on a per-trace basis. The Trace Modes (now called Trace Types) are Clear/Write, Trace Average, Max Hold and Min Hold.
Page 990 3 Short-Range Comms & IoT Mode 3.7 ACP Measurement retained and a new Trace Type command has been added. The :TRACe:MODE command is retained for backwards compatibility, and the :TRACe:TYPE, :TRACe:UPDate :TRACe:DISPlay commands introduced for ongoing use. The old Trace Modes are selected using :TRAC:MODE, whose parameters are mapped into calls to :TRACe:TYPE, :TRACe:UPDate and :TRACe:DISPlay, and the old...

Page 992 3 Short-Range Comms & IoT Mode 3.7 ACP Measurement Pressing Clear/Write stops the current sweep and initiates a new one, so Trace Average, Max Hold and Min Hold data may be interrupted in mid-sweep when Clear/Write is pressed, and therefore may not accurately reflect the displayed count.
Page 993 3 Short-Range Comms & IoT Mode 3.7 ACP Measurement Pressing Max Hold for the selected trace, or sending :TRAC:TYPE MAXH for the specified trace, sets the Trace Type to Max Hold, clears the trace , initiates a new sweep, and restarts the hold sequence, even if you are already in Max Hold. When in Max Hold, if a measurement-related instrument setting is changed(that is, one which requires new data to be taken, like Center Frequency or Attenuation), the Max Hold sequence restarts and a new sweep is initiated but the trace is not...

Page 997 3 Short-Range Comms & IoT Mode 3.7 ACP Measurement Math Function Trace Math functions perform mathematical operations between traces and, in some cases, user-specified offsets. When in a Trace Math function, the indicated function is performed during the sweep with the math function used in place of a detector.

Page 999 3 Short-Range Comms & IoT Mode 3.7 ACP Measurement Trace Math Options To generate a trace math result, you must take a sweep . The trace math engine, IMPORTANT described below, operates in concert with the sweep engine in the instrument. Until a sweep has been taken, even if the constituent traces are not in Update mode, no result is generated.
Page 1000 3 Short-Range Comms & IoT Mode 3.7 ACP Measurement DestinationTrace = 10 log(10(1/10)(FirstTrace) + 10(1/10)(SecondTrace)) The values of the trace points are assumed to be in a decibel scale, as they are internally stored. If a point in either trace operand is equal to maxtracevalue, the resultant point is also maxtracevalue.
