FHZPOS
Command/Query
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.
FHZPOS <fft_hpos>
<fft_hpos> is set in <DECIMAL NUMERIC PROGRAM DATA>
format. A value beyond the setting range is rounded to
a permissible closer value.
FHZPOS?
<fft_hpos>
<fft_hpos>:= <NR3 Numeric Response Data> format.
<fft_hpos> shows the horizontal position (position) of
the FFT waveform.
FHZZOOM
Command/Query
The FHZZOOM command sets the horizontal zoom factor of
the FFT waveform.
The FHZZOOM? query returns the horizontal zoom factor
of the FFT waveform.
FHZZOOM <fft_hzoom>
<fft_hzoom>:= {1, 2, 5, 10}
A value other than previously specified is rounded to
a permissible larger value.
FHZZOOM?
<fft_hzoom>
<fft_hzoom> shows the horizontal zoom factor of the FFT
waveform.
When FFT trace is off, FHZZOOM command reports
command-execution error (CME)．
FRQCNT?
Query
The FRQCNT? query returns the trigger signal frequency
result that is measured by internal trigger frequency
counter.
FRQCNT?
<value>
<value>:= <NR3 Numeric Response Data> format. <value>
shows the frequency of trigger signal.
