Information:
                                    The U3661 is a very portable Spectrum Analyzer.
That has been developed to be used for maintenance
inspections and the like in location
always from the lab bench and often out of doors in field.
This analyzer is small and light (about 8.5 Kg), and it has
a color LCD display.
To further increase portability, there are three-power
supply choice:
A removable battery, AC/DC Adapter or an external DC supply.

In these range, the analyzer features a maximum resolution
of 1 kHz
(100 Hz with option 26), a residual FM of 60 Hzp-p, and
noise sideband
of -100 dBc/Hz (at 10 kHz from the carrier).
The analyzer equipped with GPIB remote control, RS232 remote
control and memory
card function for saving and recalling waveform data and
panel setting.

The analyzer provides the following additional features

Three power supply source: battery, AC/DC adapter and
external DC supply.
The ability to sweep over a wide frequency range: 9 kHz to
26.5 GHz.
A precious measurement mode that uses the analyzer’s
built-in reference crystal
to measure with 1 Hz accuracy signals too weak to measure
with a counter.
Preamplifier, which is equipped with the gain 15 dB, or more
in the frequency range 9 kHz
to 3 GHz.
A memory card that can store waveform and control settings.
A digital memory LCD screen that displays signal trace
without flickering.
Digital memory also allows to marker functions for accurate
and easy reading of trace
values.
A zero span mode that allows the analyzer to be set to a
sweep time of 50 s.
Two independent channels of digital memory for simultaneous
display of two traces.
Computer-controlled operation using GPIB command set.
The analyzer is equipped with delay-sweep function.
Option 20 is the high stability 10 MHz oscillator for more
accurate measurement.
Option 26 is the active filter to have 100 Hz to 300 Hz
resolution bandwidth.
Option 72 is TV signal demodulator, such as NTSC, PAL and SECOM.
Option 74 is tracking generator to allow measuring amplitude
characteristics of devices.
