GP [n
E-8
Oscillator frequency sweep start frequency
Sets the start frequency for a subsequent sweep of the internal oscillator frequency.
In fixed point mode, n is in millihertz.
In floating point mode n is in hertz.
n ] Oscillator frequency sweep step size and type
1 2
The frequency may be swept either linearly or logarithmically, as specified by
parameter n . The step size is specified by parameter n
2
Log sweep n = 0
2
In fixed point mode, n
In floating point mode n
Linear sweep n = 1
2
In fixed point mode, n
In floating point mode n
Oscillator frequency sweep stop frequency
Sets the stop frequency for a subsequent sweep of the internal oscillator frequency.
In fixed point mode, n is in millihertz.
In floating point mode n is in hertz.
[n ]] Set/read GPIB parameters
1 2
n sets the GPIB address in the range 0 to 31.
1
n sets the GPIB terminator and the test echo function according to the following
2
table:
n Terminator
0 [CR], test echo disabled
1 [CR], test echo enabled
2 [CR,LF], test echo disabled
3 [CR,LF], test echo enabled
4 no terminator, test echo disabled
5 no terminator, test echo enabled
When the test echo is on, every character transmitted or received via the GPIB port is
echoed to the RS232 port. This is provided solely as an aid to program development
and should not be enabled during normal operation of the instrument.
is the step size in thousandths of a percent.
