Introduction
This chapter provides information about the operation of the
instrument that is useful when you first troubleshoot an instrument
failure.
The Agilent Technologies VSA is a 7 MHz to 4 GHz transmitter tester
that integrates frequency-domain and time-domain analysis to provide
advanced measurements of complex and time varying signals. The
instrument performs complex signal analysis, such as digital
modulation analysis. AM/FM/PM demodulation, vector spectrum
analysis, and time-gated spectrum analysis. Simultaneous time and
frequency domain measurements and displays improve productivity
and enhance ease of use.
