STEP-BY-STEP GUIDE
What is Spectrum Compact?
The Spectrum Compact is an ultra-light and easy to use measurement
solution. It operates in the 2 – 40 GHz frequency range. Designed specically
for comfortable outdoor use, this battery-powered device is a must-have tool
for any microwave radio engineer performing link installations or gathering
data for site planning purposes. The built-in LCD touchscreen ensures
smooth and intuitive use of the spectrum analyzer, which can be connected
directly to any standard flange antenna via an SMA connector. The industry
leading sensitivity of Spectrum Compact makes it possible to detect existing
interference paths and available radio channels with extra high precision,
which also helps avoiding alignment of the antenna on a side lobe. Data
logging is used for enhanced data processing and analysis via SAF designed
PC software.

SHORT GUIDE
TO USING
SPECTRUM
COMPACT
2
To turn on the Spectrum Compact, slide the power switch at the top of the
device towards the red dot (•). Operation time with a fully charged battery is
up to 3 hours for the 24-40 GHz model, and up to 4 hours for all other models.
The screen is divided into two sections – the graph and the control buttons.
The graph is mapped on a grid with 10 horizontal divisions and 4 ½ vertical
divisions. The horizontal axis represents a linear frequency scale that increases
from left to right. The vertical axis represents a logarithmic power scale that
increases from bottom to top. The spectrum curve is displayed in this graph.
The touchscreen has the following conguration buttons:
SWEEP CONT – start or stop the sweeping of spectrum (the button is green
when spectrum is being swept continuously and grey if the sweeping is
stopped)
SAVE – save the current spectrum curve for later review
FREQUENCY – select the centre, start, and stop frequencies
SPAN – change the displayed frequency range (difference between the start
and stop frequencies)
MARKER – set a marker at a selected frequency
HIGH CONTRAST – change the colour scheme of the interface to improve
visibility in direct sunlight
TRACE MODE – change the trace mode
NORMAL – default trace mode showing currently detected power levels
MAXHOLD – displays a blue trace in addition to the NORMAL trace showing
the highest detected power levels
CUMULATIVE – displays all the detected frequency points since the sweeping
started
3
AVERAGE 2/4/8/16 – smoothens noise effects
FILL – paints the area below the spectrum curve
TOOLS – gives access to the following options:
SETTINGS – Spectrum Compact settings
MASK MODE – set a previously saved spectrum curve as a mask overlay
on the graph
PROFILES – save the current or restore a previously saved conguration
of the Spectrum Compact
LEVEL – select the minimum and maximum displayed power levels or
select an offset (useful when an attenuator is used)
PRESET – reset the device to factory settings (use this if you don’t know
how to turn off / change a setting)
FILES – save the current spectrum curve and access previously saved
spectrum curves
RECORD - this function continuously records every scan performed for
later analysis
ABOUT – access information about Spectrum Compact (supported
frequency range, serial number, rmware version etc.)
POWER IN BAND – set up an input power measurement for a selected
bandwidth
SIGNAL ID – turn on or off the lter that reduces harmonic (false) signals
AUTO ROTATE – enable or disable the rotation of the screen when Spectrum
Compact is turned
DEMO – turn on a simulated signal pattern
4
TIME – set device time
COLOR – select different colours for the graph (the background, grid, and
spectrum curve)
BRIGHT – set the background brightness of the screen
For more in-depth information see the Spectrum Compact user manual.
Spectrum Manager
Spectrum Manager is a spectrum analysis PC software for SAF Tehnika’s
Spectrum Compact. In addition to managing rmware updates, Spectrum
Manager can be used in both real-time (together with a Spectrum Compact
device) and offline modes, and provides you with a variety of functions, such
as: PiB (Power in Band), overlay and min/max hold.
