(Continued From Previous Page)
Marker analysis functions: Peak marker, next peak marker, band
marker, harmonics marker, sideband marker, overall power, partial
power, average power, dispersion, + peak marker, - peak marker, X
dB marker, shape factor marker, ripple marker, open loop Bode
diagram marker, open loop gain marker
Calculation functions: Basic arithmetic, unwrapped phase, jw, 1/jw,
reciprocal, impulse response, equalize, phase correction, COP (co-
herent output power), open/closed loop conversion
Display functions: Frequency/amplitude, frequency/phase, frequency/
real number component, frequency/imaginary number component,
frequency/ group delay, frequency/associativity function, Nyquist
diagram, Cole-Cole diagram, Nichols diagram
Curve Fitting Function
Up to 20 groups of range poles and zeroes are sampled from
frequency response function data
Weighting: Auto weight, uniform weight, user weight
Conversion function: Sampled range poles and zeroes can be con-
verted to range poles and residue or polynomials
Synthesis Function
Frequency response function, impulse response and step response
can be synthesized from sampled range poles and zeroes or values of
entered range poles and zeroes.
Signal generator (R9211B/9211C) Except for servo analysis mode

Running zoom function: (R9211A/9211C)
When the stop frequency is less than 10 kHz, the minimum span is
10 mHz. When the stop frequency is 10 kHz or more, zoom analysis
can be done with a minimum span of 100 mHz.

and moved up and down
List modes:
Single mode 20 spectrum frequency values and level values in
the display can be selected by cursor and listed in a digital
display
Harmonics mode When the basic spectrum is set by entering the
values, the level values are listed in a digital display, and THD
(total harmonic distortion) and THP (total harmonic power) are
calculated and displayed.
Sideband mode When carrier frequency and modulated signal
frequency are set by entering the values, the upper waveband
and lower waveband power up to the 10th degree is calculated
and displayed
Horizontal axis: Linear, log
Vertical axis: Can be freely set by entering the values
