5 Mode Functions
Mode Setup
Mode Setup
The Mode Setup menu contains setup functions that are global across the entire Mode. These functions
are independent of which measurement is currently running - they are global to all measurements in the
mode, or "Meas Global." The Mode Setup functions are not the only Meas Global functions in the analyzer;
for example, the Trigger Setup functions are Meas Global, and there are even Mode Global functions (that
is, the same for all Modes) in the Input/Output menu, but the fact that they are all Meas Global is a
distinguishing characteristic of the Mode Setup functions.
The Mode Setup menu also contains the Restore Mode Defaults key. Most Meas Global functions are
restored to their preset values by Mode Preset, however some variables are more persistent and are not
preset until the Restore Mode Defaults key is pressed.
There are also a few Meas Global variables (for example, Global Center Frequency) that can be switched
to be Mode Global, that is, the same for all modes. The keys under the Global Settings key control whether
these variables are Mode Global or not.
In the Spectrum Analyzer mode, the Mode Setup functions include which radio standard and/or EMC
standard is in use and how it is configured. A set of CISPR EMC presets is available as well.
The EMC keys require either the N6141A or W6141A application or Option EMC to be installed and
licensed.

EMC Standard
Accesses a menu that allows you to select None (no EMI standard), CISPR (CISPR 16–1–1), and MIL (MIL–
461A). Each standard has a unique way of determining the couplings between detectors and RBWs, as
well as its own set of available RBW’s. The Filter Type is always Gaussian in EMI Receiver Mode.

Dependencies In Frequency Scan measurement, this key is grayed out when a scan sequence is running. If the
grayed out key is pressed, an advisory message is generated. If the equivalent SCPI command is sent,
this same message is generated as part of a “–221, Settings conflict” warning.
In Frequency Scan measurement, EMC Standard None is grayed out during a Time Domain Scan. If
the grayed out key is pressed, an advisory message is generated. If the equivalent SCPI command is
sent, this same message is generated as part of a “–221, Settings conflict; Function not available
with time domain scan type” warning.
Couplings When the EMC Standard changes to None, the Filter Type is set to Gaussian and the Filter BW is set
