The R3261/3361 spectrum analyzer, which employs a
oscillator for assuring highly stable spectrum analyzer,
wide frequency range from 9kHz to 2 .6GHz (R3261C/CN,
9kHz to 3.6GHz (R3261D, R3361D),
wide input range from -130dBm to +25dBm (R3261 C/D, R3361
C/D R3361 NK/K ) ,
-1 9dB|i to +1 32dB|i (R3261 CN, R3361CN),
wide measurement display range of 115dB and high resolution
of 30Hz, low
residual PM of 20HZp_p, less noise sideband of -105dBc/Hz
from carrier ) as well as full remote-control GPIB, and the
function for saving/recalling data and panel settings.
The R3361C/CN/D contains a tracking generator that
© This analyzer permits sweeping over a wide frequency range
to 3.6GHz (R3261D, R3361D).
© A maximum frequency resolution of 30Hz enables analysis of
signals and spurious responses
(3) High-precision frequency measurement
A reference crystal oscillator with an aging rate of 2 x 1
mounted to measure very weak signals (which cannot be
measured by any
counter ) at a resolution of 1 Hz in the counter mode.
(4) Use of a memory card permits saving/recalling of panel
(5) The field strength can be viewed and read directly after
the antenna calibration coefficient and that the QP value
based on the
CISPR standard can be observed directly.
(6) Various enhanced functions supported by digital indications
Whole information needed for spectrum analysis is displayed
on the CRT
together with signal traces«, The digital memory screen realizes
flickerless display* Various marker functions assures
easy reading even in the manual mode®
(7) Two channels of completely independent digital memories
simultaneous display of two screens.
(§) A full-remote-control GPIB is used as a powerful system
(9) The built-in tracking generator of the R3361C/CN/D
viewing of frequency attenuation of 115dB or more«
(П) The R3261 /3361 suits safety Class I of the IEC
Publication 348 (safety
Publication of the electronic measurement instrument ) ,
0) R3361NR/3361 К allows easy measurement concerning CATV.
