To explain how to use SPECTRAN, we will perform measurement of a cell
tower. Doing this, you will get to know the 3 different operation modes of
SPECTRAN, including the important HOLD function and the “panning
approach”:
It is really very simple, just follow these instructions step by
step:
Prepare SPECTRAN for operation as follows:
Remove the protective film from the display. Now
connect the triangular HyperLOG-antenna with the
SPECTRAN, using the included 1m SMA cable
(
more details on page 38
). Should you not yet have
charged the internal battery, you can also operate
SPECTRAN with the included power supply (
further
information on page 41
).
Now press the On/Off button found at the bottom-left of the device.
SPECTRAN is now powered on and starts a short calibration procedure. To be
able to orient yourself better in the following steps, the most important parts of
the SPECTRAN display are briefly explained here:

BARGRAPH
(trend display)
Depending on signal strength, the half-circle will grow or shrink. A very
handy function for quickly changing levels!
On all SPECTRAN models with
broadband detector
the bargraph dis-
play will ALLWAYS show the broadband-power even in spectrum mode.
INFO display
Shows the selected preset (frequency range). Using the keys 0-9, furt-
her presets (DECT, UMTS, etc.) are available.
MAIN display
Displays the level (signal strength) of the strongest signal in dBm.
MARKER block
(1 to 3)
Show frequency and signal strength of the strongest signals. Up to 3
markers can be displayed simultaneously.
GRAPHICS display
(here: spectrum display)
This highly flexible display field allows display of a great variety of
information, both textual and graphical (spectrum, exposure limits,
menu text, etc.)
DISPLAY-MODE status field
Shows the current operation mode of the SPECTRAN. Possible
modes: SPECTRUM (spectrum analysis), EXPOS.-LIMITS (exposure
limit calculation), AM/FM (audio output) and RF (BB Detector mode).
MODE status field
(PEAK & HOLD)
Shows the currently active mode. Possible modes: PEAK (PULSE
mode) and HOLD (Advanced HOLD mode).
