FUNC?
- R eturns the output waveform selection status. R e­
sponse: FUNC SINE;, FUNC SQUA R E;, FUNC TR I­
ANGLE;, FUNC DC;, FUNC SPULSE; or FUNC
DPULSE;.
DC [ < volts > ]
Selects d e output at the current value of the DC
parameter, or at the level specifie d by the optional
argument.
DC?
R eturns the current setting of the DC output function.
R esponse: DC < volts > ;
Parameter
AMPLitu d e < volts >
Sets the peak-to-peak output voltage (into 50 ohms)
to the value specifie d by the argument.
AMPL?
R eturns the current output amplitu d e. R esponse:
AMPL < volts > ;
DISPiay < parameter >
Changes the d isplay to show the parameter spe­
cifie d in the argument an d its current value. Par­
ameters: F R EQuency, AMPLitu d e, OFFSet, WIDth,
F R QS T A R T, DELay, F R QS T OP, NBU R st, or R A T E.
DISPiay?
R eturns the parameter that is currently shown in the
d isplay win d ow. R esponse: F R EQ;, AMPL;, OFFS;,
WID;, F R QS T A RT ;, DELAY;, F R QS T OP;, NBU R ;, or
R A T E;
F RE Quency < freq > [: < units > ]
Sets the output frequency to the argument value.
F R EQ?
R eturns the current output frequency. R esponse:
F R EQ < freq > ;
NBU R st [ < # cycles > ]
Sets the number of cycles for output in burst mo d e.
NBU R st?
R eturns the current number of cycles set for the N
BU R S T comman d . R esponse: NBU R S T <# cycles > ;
OFF Set < volts >
Sets the open-circuit offset voltage to the argument
value in volts. Argument
o
turns the offset off.
OFFSet?
R eturns the current offset setting. R esponse: OFFS
< volts > ;
PE R IOD < perio d > [: < units > ]
Changes the perio d of the output waveform. It is
an alias for the frequency parameter.

Programming
PERIOD?
R eturns the current perio d setting. R esponse: P ER ­
IOD < perio d > ; or PE R IOD O; (Perio d mo d e off).
P R EL E VEL < T IL
I
CMOS
I
ECL >
Sets pre d etermine d output levels for T T L, CMOS,
or ECL.
R A T E < rate > [: < units > ]
Sets the internal trigger inte rv al. Units: S, MS, US.
RATE?
R eturns the current internal trigger interval. R e­
sponse: R A T E < rate > ;
Trigger Mode
F R QLck ON
I
OFF
Enables/ d isables internal software control of the
output frequency.
F R QLck?
R eturns the status of the frequency lock mo d e.
R esponse: F R QL ON;, or F R QL OFF;
MODE CON T
Selects continuous output mo d e.
MODE TR IG
Selects triggere d output mo d e.
MODE BU R S T
Selects the burst trigger mo d e.
MODE GA T ED
Selects the gate d trigger mo d e. Sen d ing < G ET >
toggles the gate on or off.
MODE SYN T
Selects the frequency lock mo d e (Option 02), with
continuous output only.
MODE?
R eturns mo d e status. R esponse: MODE CON T ;,
MODE TR IG;, MODE BU R S T ;, MODE SYN T ;, or
MODE GA T E;
Trigger Source
TR IG IN T
Selects the internal trigger as trigger source.
TR IG EXT
Selects the external trigger as trigger source.
TR IG MANual
Selects the manual trigger function as the trigger
source.
TR IG?
R eturns the trigger source setting. R esponse: TR IG
IN T ;, TR IG EX T ; or TR IG MAN;
