The Advantest R3272 spectrum analyzer is a wide band, very sensitive
receiver. It works on the principle of "super-heterodyne receiver" to convert
higher frequencies (normally ranging up to several 10s of GHz) to measurable
quantities. The received frequency spectrum is slowly swept through a range of
pre-selected frequencies, converting the selected frequency to a measurable DC
level (usually logarithmic scale).
Up to four "dialog-box" type measurement
windows can be displayed simultaneously. This allows multiple signals and
measurement parameters to be viewed at the same time. For example, the R3272 can
display a transmitter signal in one window, while adjacent channel
characteristics are monitored in two other windows. This capability gives the
user more measurement information and presents it in a highly meaningful way.
The instrument also features 10 active markers which simplify evaluation of all
signal characteristics. Measurements of adjacent channel power, occupied
bandwidth and harmonic levels can be performed at the touch of a button, without
the need for manual calculation.
2个PCMCIA口可存储数据也可升级仪器软件（In addition to the PCMCIA interfaces, a broad array of application-specific measurement routines are stored in ROM, which eliminates the need to upload application programs from external mass storage devices.）
R3272 Utilizes Direct Digital Synthesis
The R3272 is the first spectrum analyzer in its price/performance range to utilize Direct Digital Synthesis (DDS), which ensures the highest level of spectrum accuracy throughout the measurement range. DDS also saves time by reducing the need to use a frequency counter for accurate measurements. The instrument's 100 dB display dynamic range and 300 Hz to 5 MHz resolution allow even the most complex signals to be evaluated.
