Vector Signal Analyzer
► A vector signal analyzer is an instrument that measures the magnitude
and phase of the measured signal at a single frequency within the range
of the instrument. Their primary use is to make in-channel measurements
on known signals, such as code domain power, error vector magnitude,
and spectral flatness. They are useful in measuring and demodulating
digitally modulated signals like cellular and wifi.
► ADI strengths here are: ADC drivers and ADCs, DDS, and clock
generation chips; our PLLs and VCOs dominate RF instrumentation and
of course our switches are everywhere.
15
Vector Signal Analyzer
(formerly Spectrum Analyzer)
► Measures and Displays Amplitude vs. Frequency (Frequency Domain) Digitizes a signal and the analysis is done in software
Can demodulate a signal as well as measure it
It is the RF version of an Oscilloscope – everyone has one on their bench
► In contrast Spectrum Analyzers measure signal using a log amp 80 dB range – AD8310 etc. dominate here in value and older instruments
► Input Frequency Range 9 kHz - 6 GHz sweet spot in market – covers 3G, 4G, LTE, UNII
Next higher bandwidths are typically 13 GHz and 26.5 GHz
► Architecture – Triple Conversion Superheterodyne High 1st IF to allow continuous frequency coverage
Third IF is digitized by ADC

How ADI’s VSA Signal Chain is Strengthened by the
Acquisition
► Functions Added
Passive Mixers
RF Switches
Narrow and Wideband VCOs
Tunable Filters
► Functions Strengthened
Nearly every RF component is improved:
► Switches are smaller, lower insertion loss, higher isolation
► LNAs are lower power, lower NF, and have better gain balance
► Wide selection of passive mixers now available
► IF amplifiers are lower power with equal or better RF specs
► Selection of digital attenuators now available
► PLLs with lower phase noise
20
Synthesizer
► A synthesizer is an instrument to generate reference or comparison
signals to test various types of equipment, a synthesizer is also a common
block which is a very important part of many types of test and
measurement equipment such as: signal analyzers, network analyzers,
and modulated frequency synthesizers (also called vector signal
generators).
► ADI’s broad portfolio of high-speed and RF components includes: a wide
selection of passive mixers; narrow- and wide-band VCOs; tunable filters;
Switches which are smaller, lower insertion loss, higher isolation; power
detectors; doublers and triplers; digital attenuators; and PLLs with lower
phase noise.

Oscilloscope (DSO scope meter)
► The oscilloscope is one of the most useful types of electronic test and
measurement equipment that continuously shows an electrical signal over
time, and which can often provide analysis and display of signal such as
amplitude, frequency, rise time, time interval, distortion, etc.
► ADI provides solutions across the complete oscilloscope from high-speed
converters to clocks, power and digital signal processing; also filters,
VGAs and PLL/VCOs.
