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.
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 on main console
1 Signal from external reference channel.
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
Oscillator frequency modulation center frequency command
In fixed point mode n sets the oscillator frequency modulation center frequency in
mHz. The range of n is 0 to 150000000 representing 0 to 150.0 kHz; in floating point
mode n sets the center frequency in Hz. The range of n is 0 to 1.5E5
Note: The span frequency plus the center frequency cannot exceed 150.0kHz; the
center frequency must also be greater than the span frequency.
Oscillator frequency modulation center voltage command
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
Oscillator frequency modulation filter control command
The value of n sets the oscillator frequency 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.
In fixed point mode n sets the oscillator frequency modulation span frequency in
mHz. The range of n is 0 to 75,000,000 representing 0 to 75 kHz; in floating point
mode n sets the span frequency in Hz. The range of n is 0 to 7.5E4.
Note: The span frequency plus the center frequency cannot exceed 150.0kHz; the
center frequency must also be greater than the span frequency.
The value of n sets the oscillator frequency 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
