n Function
0 Oscillator amplitude/frequency modulation disabled
1 Oscillator amplitude modulation enabled
2 Oscillator frequency modulation enabled
AMCENTERV[.] [n]
The value of n sets the oscillator amplitude modulation center voltage; in fixed point
mode n is an integer in the range -10000 to +10000, corresponding to voltages from -
10.000 V to +10.000 V, and in floating point mode it is in volts.
Note: The span voltage plus the center voltage cannot exceed
AMDEPTH [n] Oscillator amplitude modulation depth control
The value of n sets the oscillator amplitude modulation depth in percent, from 0 to
100
AMFILTER [n] Oscillator amplitude modulation filter control command
The value of n sets the oscillator amplitude modulation voltage low-pass filter
control in the range 0 to 10. The value of 0 gives the widest bandwidth for this filter,
with the value of 10 the lowest.
AMSOURCE [n] Oscillator amplitude modulation voltage source command
The value of n selects the source of signal used to modulate the oscillator amplitude
in accordance with the following table:
n Function
0 ADC 1 input
1 Signal from external reference channel
AMVSPAN[.] [n] Oscillator amplitude modulation voltage span command
The value of n sets the oscillator amplitude modulation span voltage; in fixed point
mode n is an integer in the range 0 to +10000, corresponding to a range from
0.000 V to 10.000 V, and in floating point mode it is in volts.
Note: The span voltage plus the center voltage cannot exceed
FMCENTERF[.] [n]
In fixed point mode n sets the oscillator frequency modulation center frequency in
mHz. The range of n is 0 to 120000000 or 250000000 representing 0 to 120.0 or
250.0 kHz; in floating point mode n sets the center frequency in the range 0 to 1.2E5
or 2.5E5
Note: The span frequency plus the center frequency cannot exceed 120.0 or
250.0kHz; the center frequency must also be greater than the span frequency.
FMCENTERV[.] [n]
The value of n sets the oscillator frequency modulation center voltage; in fixed point
mode n is an integer in the range -10000 to +10000, corresponding to voltages from -
10.000 V to +10.000 V, and in floating point mode it is in volts.
Note: The span voltage plus the center voltage cannot exceed
FMFILTER [n] Oscillator frequency modulation filter control command
The value of n sets the oscillator frequency modulation voltage low-pass filter
