Information
Powermeter System 6460S
Wattmeter Absorption CT596 and
Wattmeter Set
6625-99-541-6389 comprise three specific collections of
instruments and Accessories,
as detailed below, selected and tested for military
applications.
These equipments measure power in the range 300 nW to 1 W in
a frequency range
of 10 MHz to 18 GHz and meet the environmental requirements
of Joint-Services
Specification REMC/20/FR (Iss. 6) Cat. I I I .
2. They are based on the tft Powermeter ή460/ 1 which, in
conjunction with a
series of tft Power Heads, can provide a total measuring
range of 30 nW
to 3 W from 10 MHz to 40 GHz.
FEATURES
5. Type 6460/1 Powermeter in conjunction with the 6420 and
6440 series of
tft Power Heads, is a highly accurate instrument which
measures radio frequency
power over an extremely wide frequency and power range. It
measures
and indicates the average power absorbed by the power head
in use, and accepts
amplitude and frequency modulated, pulsed and c.w. signals.
Tables 1 and 2
list tft power head characteristics.
6 . The powermeter features automatic scales selection,
which ensures that
only the scale corresponding to the sensitivity of the power
head in use is
activated. Other features include a swiLch which enables Lhe
selection of
ciLher normal or fast Amplifier response time, output
terminals for measurement
systems using external recorders or digital voltmeters and
two paralleled
input connectors which permit power head connections at the
front or rear of
Lhe 6 4 6 0 /1 .
7. An intern,il Ή) ИИ/, r . f . cali bra Cor is ^ il ted.
['his produces three; preset
power levels of i mW, 10 niW or 100 mW depending on the
power rating of Lhe
power head being used. The Calibrator automatically supplies
the correct
oui.puL to power head.
8 . The 6460/1 is suitable for use in a wide variety of
applications, including
portable and field use (when used with the optional rechargeable
battery pack) fixed stations and laboratory bench set-ups.
Since all tft
power heads will operate with the 6460/1 a single instrument
with different
power heads can be applied to a wide variety of measurement
applications.
The type 963R Junction Box, which permits simultaneous
connection of up to
five power heads, facilitates many applications. Junction
boxes can be cascaded
to permit operation of an even greater number of power heads.
9. By using the proper rack adapter the 6460/1 can be
rapidly rack-mounted
by itself, with any oLher MT Sanders unit packaged in this
half-rack configuration
or with 198 mm (7 25/32 in) wide half-rack units of other
manufacturers.
