2. Overview and System
Requirements
This section describes the SeeGull MX
Scanning Receiver, including the applicable
system configuration and software
requirements.
2.1.
General Description
The SeeGull MX Scanning Receiver (
) is a tool for signal strength and
modulation measurement, engineered for
the rigors of mobile network testing during
planning, installation, and maintenance of
wireless networks. It supports up to six
protocols with either 4 or 8 band-designated
receive antenna (RX) ports.

The USB communication link allows the
host to control the operation of the scanner
and to receive measurement results. (Refer
to
Section 4
for more details).
Initial Inspection
Upon receipt of the scanning receiver,
inspect the shipping container and verify
that the contents are complete and match
the packing list. The receiver should look
similar to the picture in

Enhanced Power Scan (EPS
TM
) Option
(OP514)
EPS Mode provides customizable power
measurements, improving flexibility and
precision over RSSI and Spectrum Analyzer
measurements for highly-tuned analysis of
individual parts of the RF signal. EPS
features include:
Absolute Time Stamp
Auto and Immediate Measurement
Modes
Ability to set both Time and Frequency
parameters
Measure Frequency Spans from 7.5 kHz
to 20 MHz user selectable in multiples of
2.5 kHz
Measures Time Periods from 1 chip (50
µs) to 20,000 chips (1sec)
Spectrum Analyzer Option (OP513)
The built-in Spectrum Analyzer feature
provides an effective means to detect and
troubleshoot frequency-related problems.
The Spectrum Analyzer shows a wealth of
information about the signal spectrum that is
not obtainable from the standard channel
power measurement.
