Standard System Features – continued

Feature Description Benefits

Relative Signal Strength Meter

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 find this

feature convenient in performing propagation

studies to identify weak coverage areas.

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.

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 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.

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.

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.

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.

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 5 kHz steps are keypad-selectable.

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 desensi-

tization 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.

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 filter 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.

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.
