Internal Oscillator - Ametek 7280 Instruction Manual

EQU n Output result of equation #1 or equation #2
The value returned is the output of the user equation #1 (n = 1) or equation #2 (n =
2), where the equations are defined using the Equation Setup menus (see section
5.3.09). The possible range is ±2,147,483,647 (signed 32-bit integer).
? Fast Data Transfer command
The ? command offers a method of reading a combination of instrument outputs
which are sampled at the same time, thereby ensuring that they are correlated.
The response to the ? command is the output(s), expressed in floating point mode,
specified by the present setting of the Curve Buffer Define (CBD) command (see
section 6.4.09) and separated by delimiter character(s) defined by the DD command.
Hence for example, if CBD is set to 19, the response to the ? command will be:
<X output, in floating point mode><delimiter>
<Y output, in floating point mode><terminator>

6.4.06 Internal Oscillator

OA[.] [n] Oscillator amplitude control
In fixed point mode n sets the oscillator amplitude in millivolts. The range of n is 0 to
1000 representing 0 to 1 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 1.000 V
In fixed point mode, n is in millivolts 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 1.000 V
In fixed point mode, n is in millivolts 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 1.000 V
In fixed point mode, n is in millivolts 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
2000,000,000 representing 0 to 2.000 MHz.
In floating point mode n sets the oscillator frequency in Hz. The range of n is 0 to
2.0E6
