Microwave Frequency Counters

Perfect solution in the field...

The 3000-series of combined microwave
counters and power meters, providing simulta­neous measurement of both frequency and
power, suits both field, lab bench and test rack
environments.

For field applications like installation, mainte-
nance and calibration of microwave links, ra­dar CW, microwave transmitters, DAB or
DTV links, satellite ground stations or radio
base stations, the models in the 3000-series
give you ultra-high accuracy in a portable
compact, lightweight and rugged design. A
weather-resistant instrument back-pack is in
cluded.

Atomic clock accuracy in a true portable for
mat: You can bring cal lab accuracy out into

the field thanks to an integrated rubidium or
high-stability OCXO oscillator. Since both
frequency and power verification are standard
measurements in field installation and mainte
nance, you can have both instruments in one
box, meaning less to carry around. The same
input connector is used for both measure
ments, which simplifies operation. An optional
battery pack is used in environments where no
AC power is available, or to keep an OCXO
continuously heated during transport for opti
mum performance. The battery typically pro
vides over 3 hours of continuous operation and
automatically charges whenever the counter is
connected to the AC mains.

Very Easy to Use: To eliminate operator mis
takes, the instruments are very easy to use and
require no costly training. The front panel
controls are self-explanatory and the read out
of result is unambiguous due to the bright
LED display which ensures full visibility,
whether in full sunlight or in the dark.

Lower operating costs than any competitive
solution: In addition to the very affordable

mm frequency counter, a power meter and a fre

quency reference.
purchase price, the instruments are very dura­ble and reliable, and will give you trouble-free
operation year after year. A 5 year warranty
comes with each instrument.

...or on the bench

For bench ant test systems applications like
R&D, Service, incoming inspection, quality
control and manufacturing test of RF compo­nents, systems or subassemblies, microwave
transmitters/receivers, radar equipment etc, the
models in the 3000-series gives you ultra-high

­performance and remote GPIB connectivity.

Three instruments in one: Measurements are

-

accurate and fast, with less than 60 ms acquisi
tion time. With the Rubidium oscillator option,
you will not only get a high-accuracy micro
wave counter, but also a 10 MHz reference
output frequency for the local lab or for the

­ATE-rack, where you can supply other instru

Oscillator Options

A wide choice of internal time base oscillators are
available; the standard TCXO oscillator, two high
stability OCXO oscillators, and a Rubidium Fre­quency Standard. Please see table below for
specs.

Telecommunication professionals often have a re­quirement to measure and verify base station ref­erence oscillators at remote sites. These base
station oscillators must be calibrated very
accuratly. The optional internal Rubidium Fre
quency Standard, along with the standard 0.01 Hz
