24–40 GHz SPECTRUM COMPACT v.2 (FW V5.3.3)
OPERATION
7
When Spectrum Compact is connected to a power source, a quick press of the
button allows checking the battery status without turning on the device. While
charging, the LED located under the transparent button will
glow
red
. If the device is
attached to a power source, but the battery is not charging (e.g. the power source
does not provide enough current for charging), the LED will
flash red
. When fully
charged, the LED will
glow
green
.
It is recommended to fully charge and discharge a new device few times to
ensure that the battery indication is as accurate as possible.
The screen of the spectrum analyzer is divided into two parts: the graph and the
buttons, which represent the available menus and options. The horizontal axis of the
graph represents linear frequency range in megahertz (MHz). Frequency value
increases from left to right. 1 pane represents 1/10
th
The displayed frequency range can be selected at the
of the graph represents logarithmic input power range in decibels referenced to one
milliwatt (dBm). The input power level increases from bottom to top. The displayed
input power range can be adjusted at the
LEVEL
menu. Above the graph the input
power level at the CENTER frequency is displayed in
yellow
(except for CUMULATIVE
trace mode, see
).
Tapping the clock in the upper right corner swaps the displayed time/date format.
To save a spectrum curve for later review, use the
in Spectrum Compact Curve file format (.scc). They can be reviewed in
and are accessible when the device is connected to a computer.
Tapping the upper left corner takes a screenshot. The screenshots are saved as
bitmap (.bmp) images. The screenshots are available only when Spectrum Compact
is connected to a computer.
The essential functions of the spectrum analyzer are accessible from the main
screen. All of the menus and options are described in detail in the following chapters.
Exceeding the critical input power level of 0 dBm may cause irreversible
damage to the equipment
!
If the overall detected signal power is higher than -40 dBm, a
red
warning
“OVERLOAD” will be displayed above the graph.
Initially perform a scan at full (default) span to detect overload presence since
a signal outside of the displayed frequency range also contributes to overload!
