AR5000c - frequency coherent

When making critical

measurements, the frequency

coherence is very important

whether a single or multiple unit is

employed. Just like optical

telescopes, the output from

several receivers may be ADDED

together to provide greater

performance, however their

frequencies must be absolutely

coherent. This involves the use of

a single reference for all oscillators

employed throughout the receiver.

Several receivers may then be

connected to a single external

frequency standard safe in the

knowledge that their outputs will

be coherent.

The AR5000c now provides this

commercially required capability.

The “C” version may be provided

to order in either the standard

AR5000 format or with two of the

+3 additions of AFC and NB. If

you are a commercial operator

with this application in mind,

please request the separate

specification information for the

AR5000c.

AR5000+3 - Sync AM, AFC, NB

The “+3” version offers even

more with synchronous AM (upper

side band, lower side band and

double side band with excellent

lock range), AFC (Automatic

Frequency Control for accurately

tracking moving transmissions or

unusual band plans) and Noise

Blanker.

★★★★✩★★★★✩

★★★★✩ AR5000+3 awarded four stars by both the authoritative

Passport To World Band Radio and World Radio & TV Handbook

Passport to World Band Radio’99.

“Front-end selectivity, image rejection, IF rejection,

weak-signal sensitivity, AGC threshold and frequency

stability all superior”.

“Unlike virtually every other receiver we have tested

over the past 21 years, the frequency readout is

unfailingly accurate to the nearest Hertz. This should

make the AR5000+3 of exceptional interest to

broadcast engineers”.

World Radio TV Handbook’99.

Speaking of the AR5000+3 in conclusion...

“Compared with the ICOM ICR-8500 it offers

considerably more features, better strong-signal

handling, wider coverage and decidedly superior

filters".
