Math FHZPOS
Command/Query
DESCRIPTION The FHZPOS command sets the frequency at the center of
the screen in Hz, to set horizontal position of FFT
waveform.
The FHZPOS? query returns the frequency at the center
of the screen of FFT waveform in Hz.
COMMAND SYNTAX FHZPOS
is set in
format. A value beyond the setting range is rounded to
a permissible closer value.
QUERY SYNTAX FHZPOS?
RESPONSE FORMAT
:= format.
shows the horizontal position (position) of
the FFT waveform.
REMARKS
Math FHZZOOM
Command/Query
DESCRIPTION The FHZZOOM command sets the horizontal zoom factor of
the FFT waveform.
The FHZZOOM? query returns the horizontal zoom factor
of the FFT waveform.
COMMAND SYNTAX FHZZOOM
:= {1, 2, 5, 10}
A value other than previously specified is rounded to
a permissible larger value.
QUERY SYNTAX FHZZOOM?
RESPONSE FORMAT
shows the horizontal zoom factor of the FFT
waveform.
REMARKS When FFT trace is off, FHZZOOM command reports
command-execution error (CME)．
Horizontal FRQCNT?
Query
DESCRIPTION The FRQCNT? query returns the trigger signal frequency
result that is measured by internal trigger frequency
counter.
COMMAND SYNTAX
QUERY SYNTAX FRQCNT?
RESPONSE FORMAT
:= format.
shows the frequency of trigger signal.
