Advantest Corporation TR4172 Spectrum analyzer
Manufacturer
Advantest Corporation
Model: TR4172

Category: Measurement instruments
Group: Spectrum analyzer
Description:
Information:
                                    The TR4172 spectrum Analyzer is a microprocessor-controlled,
intelligent instrument with a frequency range from 50 Hz to
1800 MHz. in addition to the spectrum analyzing function,
the integrated tracking generator of TR4172 enables analysis
of frequency response of filters, amplifiers, and so on.

TR4172 is the first spectrum analyzer with a capability for
measuring phase response and group delay of filters or
amplifiers at resolutions of down to 0.1 deg and 0.1 ns
respectively, up to a frequency of 1800 MHZ.

The integrated tracking generator, along with the analyzer’ร
intelligent control capability, permits correction of the
analyzer's frequency response itself allowing precision
level measurement.

A wide dynamic range is ensured by the low higher-harmonic
distortion level of 90 dB at and above 20 MHz, with respect
to a signal level of -40 dBm.

The display screen has a dynamic range of more than 95 dB
and permits direct observation of filter responses with
large attenuations.

The vertical resolution of the scale can be selected from
10, 5, 2, 1, and 0.1 dB per division, observation of a
ripple level of even 0.01 dB is possible with the maximum
resolution setting.

Use of the SAVE switch makes various measurements available,
with which up to eight sets of measurement condition data
are stored in the internal registers and recalled as needed.
Since the internal memory is backed up by a battery, its
contents remain intact even if the device is unplugged from
its supply outlet.

All front panel functions are remotely controllable with the
GPIB interface (standard supply) for automatic measurement.
The CRT display presents all pertinent measurement data. The
signal response trace and measurement data on the screen can
be output to an X-Y plotter simply by connecting the
instrument*ร GPIB connector to the plotter'ร input with a
GPIB cable and operating the relevant front-panel switches,
without the need for running an output program on the GPIB
controller.

TR4172 also provides various convenient features to enhance
measurement flexibility and efficiency, such as multiple
marker, zoom, automatic centering, automatic enlargement,
auto-peak search, logarithmic scaling, and four page
memorized display.
