Error Vector Magnitude

The CM 816 Error Vector Magnitude
(EVM) application provides a
constellation diagram that gives a
clear, visual picture of how close the
measured signal aligns with an ideal
reference. It works with C4FM,
CQPSK, and LSM modulation
types, and includes a user-definable
tolerance setting which allows the
operator to quickly visualize the
performance under test.

The Software also generates a
histogram distribution of the EVM
metrics, providing another form of
visual analysis of the transmitter’s
performance over time.

The CM816 EVM option can be
used with any R2625C model
analyzer or R2670B equipped
with the CM801 enhanced digital
hardware module and CM813
Project 25 option.

AutoTest/AutoTune

For Digital / P25 Equipped Radios

Automated Test and Alignment

AutoTest and AutoTune perform all
recommended factory alignment procedures
and critical transmitter/receiver performance
tests – in a fraction of the time it takes to

perform manually.

Fast, accurate, easy to use

The AutoTest and AutoTune software
applications takes the guesswork out of
aligning your radios. Simply connect the
radio, select the tests and/or alignments you
wish to perform from the menu, and press
“Run.” The software automatically “reads”
the radio’s internal programming, configures
the analyzer, and takes measurements
as needed. If required, internal radio
adjustments are then automatically performed
to bring the radio into proper alignment. All
measurement results and initial/final softpot
settings are stored for easy retrieval.

Now even non-technical personnel can
fully test and align your radios – freeing
technicians to do actual repairs.

Standard System Features

Feature Benefits

High Performance Spectrum Analyzer

The built-in High Performance Spectrum Analyzer will display a
window of RF spectrum anywhere within the 400 kHz to 1 GHz
operating range of the unit. The EXPAND softkey enlarges the display
to fill the LCD and retains dispersion and center frequency control.

The High Performance Spectrum Analyzer adds Marker functions for
more precise measurements of level and frequency (both absolute and
delta). Included with the marker functions are additional dispersion
selections – up to 10 MHz per division, plus the additional freeze,
peak hold, and max hold features.

Terminated RF Wattmeter

RF power anywhere in the operating range of 400 kHz to 1GHz is
automatically measured by the Communications System Analyzer
when tuned to that frequency. The built-in RF load dissipates up to
125 watts for one minute.
If a high power transmitter should be keyed into the unit for any
longer, the LCD changes to read “WARNING RF OVERLOAD,”
thus warning the technician to un-key.

Programmable Test Memory

Channel Presets – The unit has 30 memory locations which can be used

to store preset channel information. Channels can readily be selected
individually or automatically scanned over a user-defined range.

Programmable Test Setups (standard in R2670; optional in R2600
and R2625) – You can easily program and store up to 15 of the most

commonly used test configurations, including all test conditions,
measurement display formats, and levels. These memory settings
operate independently of the channel presets.

The ability to observe the spectrum display for detailed analysis
through the use of multiple Markers provides a significant advantage.
The tuning knob retains control of the center frequency even in the
EXPAND mode to perform fast sweeps or fine tuning. This allows
you to quickly locate and identify signal carriers.

This feature provides calibrated RF power measurements eliminating
the need for a separate wattmeter. The LCD also displays frequency
error and modulation level readings simultaneously.

Channel Presets – This feature allows quick access to frequently used
channel location information to speed testing. Scanning allows automatic
monitoring and measurement of activity on channels of interest.

Programmable Test Setups (standard in R2670; optional in R2600
and R2625) – You can significantly reduce the number of key presses

required to set up more commonly used test configurations, greatly
increasing your efficiency while promoting uniform test procedures.
You can also assign a custom name to the configuration for easy recall.

In addition to reading frequency error and modulation, a digital readout
relative signal strength meter has been included. Sensitivity is specified
to -100 dBm at the antenna port for FM signals and extends up to 125
watts at the RF I/O port. The LCD display will automatically convert
to a terminating “watts” display as the level increases.

This feature, in conjunction with an external antenna, allows remote
monitoring of distant transmitters to check for antenna, transmission
line or P.A. problems. Many users also f ind this feature convenient in
performing propagation studies to identify weak coverage areas.

RF Scan / RF Counter Function

RF Scan operates in the monitor mode and provides a function
similar to a 1 GHz counter. This feature automatically scans a
user-defined frequency range and locks on the applied signal. Any
RF carrier above 20 MHz can be located within 5 seconds and the
reception displayed with digital readouts.

Duplex

Full output level control from -130 dBm to 0 dBm over the entire range
of the instrument is available from the RF I/O port (-130 dBm up to

-50 dBm) and the generator port (-80 dBm to 0 dBm). Variable offsets
from 0 to ±999.995 MHz in 2.5 kHz steps are keypad-selectable.

Tracking Generator (standard in R2670; optional in R2600 and R2625)

The combining of the capabilities of the sweep generator and the
spectrum analyzer into a Tracking Generator function allows the user
to view the performance characteristics of many RF f ilter devices.
Display range is operator selectable from a 200 kHz window up to a
50 MHz window anywhere in the 400 kHz to 1GHz spectrum.

Signaling Simulator: Encoder and Decoder

The System Analyzer includes the capability of encoding and decoding
PRIVATE LINE (PL), DIGITAL PRIVATE LINE (DPL), and single
tone sequences as well as multi-tone sequences including DTMF
signals, 5/6 tone paging, Select V and up to 20 sequential tones.
Decoding displays include tone frequencies and time durations of the
individual tones. The unit can also encode tone remote signaling.

This feature allows convenient and immediate verification of the
programming of a multi-channel radio. By automatically tuning the
analyzer’s receiver to the detected carrier, immediate measurement
data can be taken without having to enter new frequency data
via the keyboard.

The duplex generator provides enhanced capability to service
equipment, such as repeaters and full duplex radios. Full RF level
control, as well as full internal and external modulation capability
allows receiver desensitization and transmitter tests to be performed
simultaneously through one port, if desired.

The wide offset range extends the functionality to include cross
band repeater systems, as well as enhanced receiver and transmitter
troubleshooting capabilities.

Diagnosis and adjustment of critical receiver front ends, IFs, helical
filters, cavities, combiners and duplexers can be made in a few
minutes, quickly and easily with the flexibility of a tracking generator
at your fingertips.

The signaling capability of the unit reaches a broader range of
service applications with its decode capability. This gives you a more
flexible test instrument which aids in servicing paging equipment and
specialized signaling encoders, as well as mobile, portable and other
radio products. The signaling simulator can perform a full system
check-out faster, with more accuracy than ever before.

General Purpose & Modulation Oscilloscope

The oscilloscope has a 50 kHz bandwidth for audio waveform
analysis. The display can be triggered over the full screen range to a
fixed reference level. Triggering in both automatic and normal modes
is provided for synchronizing the horizontal timebase to the vertical
input signal. Internal or external inputs allow observation of both
generated and monitored modulation signals. Softkeys provide for an
enlarged full screen display.

Flash Upgradable Software

High-Speed serial port and flashable memory permit programming
firmware updates from an external PC.

Cable Fault (standard in R2670; optional in R2600 and R2625)

Cable fault and length are RF measurement features which help the
technician isolate cable defects. Supported by on-screen prompts and
user-selectable Help messages, you can quickly set up and accurately
determine the distance to a fault on a coaxial cable. The distance to
fault (or cable length) is computed and displayed in feet or metric units.

RS-232/Serial Interface (standard) IEEE-488-2 Interface (optional)

A full bi-directional RS232 port is standard and includes the capability
to respond to serial input command vocabulary and return measurement
results as a serial output stream. Included are user-selectable baud rates
(up to 115.2 Kbps) and start, stop and parity bit selection. In addition,
this dual function port can drive a serial printer to print out data and
graphic displays. The optional IEEE remote interface option contains
the necessary hardware and software for IEEE-488.2.

Recovered audio or internally produced audio can be displayed
visually for deviation measurements. Additionally, detection of an
asymmetric modulation or audio distortion can be achieved with
waveform analysis. With internal and external triggering and a freeze
display single sweep, this unit duplicates many features of more
expensive scopes. The markers allow detailed analysis to measure
waveforms displayed on the LCD. The EXPAND function provides an
enlarged, easy to interpret view of the signal for quick analysis.

Quick and easy access to future software updates.

Cable fault locating techniques are mandatory for site servicing,
where visual inspection is not practical, safe, or effective in detecting
hidden or cold-flow damage. The semi-automatic operation of the
cable faultfinder precludes the use of mathematical formulas and
manual calculations, maximizing your on-site productivity.

If you have large volume repetitive testing requirements, this feature
allows you to write your own programs to reduce test time costs.
Printed results can be used as part of the service shop’s internal
quality control system and can be used to demonstrate performance
to the radio equipment user.
