Internal Oscillator - Ametek 7230 Instruction Manual

6.7.06 Internal Oscillator

OA[.] [n] Oscillator amplitude control
In fixed point mode n sets the oscillator amplitude in microvolts rms. The range of n
is 0 to 5000000 representing 0 V to 5 V rms.
In floating point mode n sets the amplitude in volts.
ASTART[.] [n] Oscillator amplitude sweep start amplitude
Sets the start amplitude for a subsequent sweep of the internal oscillator amplitude,
in the range 0 to 5.000 V
In fixed point mode, n is in microvolts rms, and in floating point mode n is in volts
rms
ASTOP[.] [n] Oscillator amplitude sweep stop amplitude
Sets the stop amplitude for a subsequent sweep of the internal oscillator amplitude,
in the range 0 to 5.000 V
In fixed point mode, n is in microvolts rms and in floating point mode n is in volts
rms
ASTEP[.] [n] Oscillator amplitude sweep step size
Sets the amplitude step size for a subsequent sweep of the internal oscillator
amplitude, in the range 0 to 5.000 V
In fixed point mode, n is in microvolts rms and in floating point mode n is in volts
rms
OF[.] [n] Oscillator frequency control
In fixed point mode n sets the oscillator frequency in mHz. The range of n is 0 to
120000000 or 250000000 representing 0 to 120 kHz or 250 kHz.
In floating point mode n sets the oscillator frequency in Hz. The range of n is 0 to
1.2E5 or 2.5E5
FSTART[.] [n] Oscillator frequency sweep start frequency
Sets the start frequency for a subsequent sweep of the internal oscillator frequency,
in the range 0 to 120 or 250 kHz.
In fixed point mode, n is in millihertz, and in floating point mode n is in hertz.
FSTOP[.] [n] Oscillator frequency sweep stop frequency
Sets the stop frequency for a subsequent sweep of the internal oscillator frequency,
in the range 0 to 120 or 250 kHz.
In fixed point mode, n is in millihertz and in floating point mode n is in hertz.
FSTEP[.] [n n ] Oscillator frequency sweep step size and type
