Initial power-up
Slide power switch towards the red dot (
●
) to power on your Spectrum Compact. If
the battery meter is indicating
LOW BATTERY
, connect USB charger via USB
connector and charge the Spectrum Compact. Full charging cycle (with 1A power
source) is approximately 5 hours for P/N J0SSAP11/J0SSAP12/J0SSAP13 and 8-10
hours for P/N J0SSAP14.
Operation time with a fully charged battery is up to 4 hours for P/N
J0SSAP11/J0SSAP12/J0SSAP13 and up to 3 hours for P/N J0SSAP14. Using a
Spectrum Compact while charging it via USB will prolong its operation time by
approximately 1 hour, but it can’t ensure continuous operation.

Connecting to antenna
1)
Connect an appropriate 50 Ω coaxial cable to SMA or 2.92mm connector (antenna
port).
2)
Attach waveguide-to-coaxial converter to an antenna or radio flange.
3)
Attach the coaxial cable to the waveguide-to coaxial converter.
If Spectrum Compact is attached directly to a radio, add
a 60dB attenuator to the coaxial cable (if
measurements will be done with an input signal above
-20dBm) and enter the correct offset value in
TOOLS
LEVEL
OFFSET.
Exceeding the critical input signal level (0dBm) may
cause irreversible damage to the equipment.
Initially perform scan at maximum (default) span to
detect
overload
presence.
Apply
appropriate
attenuation if detected.
In order not to affect operation of scannable equipment
do not scan operating frequencies when directly
connected to a coupling port.
