Advantest R9211B FFT Servo Spectrum Analyzer
Feature:
Minimum Frequency: 10mHz
Maximum Frequency: 100kHz
The R9211B has a signal generator and is ideal for component oscillation analysis or measurement of servo circuits. It continues the servo measurement know-how employed in previous modes, using ADVANTEST's exclusive SSS (Swept Sine Sweep) technique. It realizes a maximum amplitude difference of +/-0.1 dB between channels and maximum phase difference of +/-1.0 degrees between channels.
It has a built-in summation amplifier for use in open loop characteristics evaluations; low SG output impedance; and a servo measurement function using a log frequency table, making it ideal for use in servo design and development. There has been a great improvement in operability and reduction in measurement time over previous models. There is an optional digital signal generator output and a feature allowing analysis by digital input. Also, new applications and the servo analysis mode have been added so that measurement can be done in 5 domains.
