4.2.1.5 Function Keys
Function keys provide access to the most common measurement settings and func-
tions.
A detailed description of the corresponding functions is provided in the User Manual.
Table 4-2: Function keys
Function key Assigned functions
FREQ Sets the center frequency and the start and stop frequencies for the fre-
quency range under consideration. This key is also used to set the fre-
quency offset and the signal track function.
SPAN Sets the frequency span to be analyzed
AMPT Sets the reference level, the displayed dynamic range, the RF attenua-
tion and the unit for the level display
Sets the level offset and the input impedance
Activates the (optional) preamplifier
BW Sets the resolution bandwidth and the video bandwidth.
SWEEP Sets the sweep time and the number of measurement points
Selects continuous measurement or single measurement
TRACE Configures the graphical analysis of the measurement data
MEAS Provides the measurement functions:
Measurement of multicarrier adjacent channel power (Ch Power ACLR)
Carrier to noise spacing (C/N C/N
0
)
Occupied bandwidth (OBW)
Spectrum emission mask measurement (Spectrum Emission Mask)
Spurious emissions (Spurious Emissions)
Measurement of time domain power (Time Domain Power)
Third-order intercept point (TOI)
AM modulation depth (AM Mod Depth)
MEAS CONFIG Used to configure measurements and data input and output
LINES Configures display lines and limit lines
MKR Sets and positions the absolute and relative measurement markers
(markers and delta markers)
Selects special marker functions
MKR-> Used for search functions of the measurement markers (maximum/mini-
mum of the trace)
Assigns the marker frequency to the center frequency, and the marker
level to the reference level
Restricts the search area (Search Limits) and characterizes the maxi-
mum points and minimum points (Peak Excursion)
TRIG Sets the trigger mode, the trigger threshold, the trigger delay, and the
gate configuration in the case of gated sweep
PEAK Performs a peak search for active marker. If no marker is active, normal
marker 1 is activated and the peak search is performed for it.
