A detailed description of the corresponding menus and the other function keys is provided in
the Operating Manual on CD-ROM.
Function key Assigned functions
ON/STANDBY Switches the instrument on and off.
PRESET Resets the instrument to the default state.
FREQ Sets the center frequency as well as the start and stop frequencies for the
frequency band under consideration. This key is also used to set the frequency
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 attenuation and
the unit for the level display. This key is also used to set the level offset and the
input impedance.
MKR Sets and positions the absolute and relative measurement markers (markers
and delta markers). In addition, the following measurement functions are
assigned under this key:
• Frequency counter ( SIGNAL COUNT )
• Fixed reference point for relative measurement markers ( REFERENCE
FIXED )
• Enlargement of the measurement area ( MARKER ZOOM )
MKR-> Used for search functions of the measurement markers (maximum/minimum 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 maximum
points and minimum points ( PEAK EXCURSION ).
MKR FCTN Provides additional analysis functions of the measurement markers:
• Noise marker ( NOISE MEAS )
• Phase noise ( PHASE NOISE )
• n dB down function
• AM/FM audio demodulation
• Peak list
BW Sets resolution bandwidth, video bandwidth and the two ratios "resolution
bandwidth/video bandwidth" and "span/resolution bandwidth" in the case of
automatic coupling.
SWEEP Sets the sweep time and the number of measurement points.
Selects continuous measurement or single measurement.
