89600 Vector Signal Analyzers
Data Sheet
The following specifications describe the warranted
performance of standard 89600 Series VSA systems
and equivalent 89600S systems integrated by Agilent
Technologies. The performance of standard 89610A
systems is specified in the E8408A four-slot VXI
mainframe.
1
The performance of standard 89611A,
89640A, and 89641A systems is specified in E8408A
1
four-slot, and E8403A213-slot VXI mainframes. These
specifications describe the nominal performance for
other, non-standard 89600S configurations.
These specifications describe warranted performance
over a temperature range of 20 to 30 °C and include
a 30-minute warm-up from ambient conditions.
Parameters identified as “typical” or “characteristic”
are included for informational purposes only and are
not warranted. To aid in understanding analyzer
performance capabilities, measurement units and
specification terms are provided in the glossary at the
end of this document.
The Agilent 89600 Series vector signal analyzers come
standard with two sets of application software: vector
signal analysis and spectrum analysis. The vector signal
analysis application software is used to analyze complex
signals in the time, frequency, and modulation domains.
The spectrum analyzer application software emulates
a traditional spectrum analyzer, providing fast, highresolution signal magnitude measurements while sweeping
across a user-defined frequency span. Unless otherwise
indicated, the specifications in this data sheet apply to
both sets of application software.
1. With backplane connector RF shielding (Option E8408-80900) and enhanced
current supply (Option E8408-100).
2. With backplane connector RF shielding (Option E1401-80918).

Time and Waveform
1
The 89600 series vector signal analyzers have two signal processing modes: baseband
and zoom. These two processing modes affect the appearance and the duration of
input waveforms displayed by the 89600s. Most 89600 measurements are made with
a non-zero start frequency, called the Zoom mode. In these cases, the time domain
display shows a complex envelope representation of the input signal – that is, the
magnitude and phase of the signal relative to the analyzer’s center frequency. This
provides powerful capability to examine the baseband components of a signal without
the need to first demodulate it.
Baseband mode refers to the special case where the measurement begins at 0 Hz.
Here, the input signal is directly digitized and the waveform display shows the entire
signal (carrier plus modulation), very much as an oscilloscope would.
Time record characteristics In the 89600 VSA application, measurements are based on time records. A time record
is a block of samples of the signal waveform from which time, frequency, and
modulation domain data is derived. Time records have these characteristics:
Time record length (main time) (Number of frequency points – 1)/span with RBW mode set to arbitrary, auto-coupled
Time sample resolution 1/(k x span)
where: k = 2.56 for time data mode set to baseband
k = 1.28 for all other modes (default) including zoom
Span = currently selected frequency span
Time capture characteristics In time capture mode the 89600 VSA application captures the incoming waveform
gap-free into high-speed time capture memory. This data may then be replayed
through the analyzer at full or reduced speed, saved to mass storage, or transferred to
another software application.
When time analyzing the captured waveform, users may adjust measurement span
and center frequency in order to zoom in on a signal, as long as the new measurement
span lies entirely with in the originally captured span.
Time capture memory size Zoom mode. For baseband mode, increase values by 2x.
