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.
