SCPI COMMAND SUMMARY

Pulse Subsystem

 

Since frequency and period are inversely related, if both are sent

 

in the same message, only the last one is applied. If the WIDth

 

command and either the FREQuency or PERiod command are sent

 

in the same message, they must be accepted without error if the

 

resulting pulse is possible.

 

 

 

• PULSe:FREQuency Cnum>[freq suffixllMAXimumlMINimum

 

• PULSe:FREQuency? [MAXimum IMINimum]

 

Sets and queries the frequency of the internal pulse generator. The

 

resolution of the frequency is such that the resulting period is set to a

 

resolution of 1 ps. The *RST value is 500 kHz.

 

• PULSe:PERiod <num>Ctime suffix] 1MAXimumlMINimum

 

• PULSe:PERiod? [MAXimumlMINimum]

 

Sets and queries the period of the internal pulse generator. The

 

resolution of this is 1 ps. The *RST value is 2 ps.

 

• PULSe:WIDTh Cnum>[time suffixllMAXimumlMINimum

 

• PULSe:WIDTh? [MAXimumlMINimum]

 

Sets and queries the width of the internal pulse generator. The *RST

 

value is 1 ps.

 

• PULM:SLEW Cnum>[time suffix]lMAXimumlMINimum

 

• PULM:SLEW? CMAXimumIMINimuml

 

Sets and queries the rise time for the pulse modulation. The typical

 

usage is MAX I MIN since calibrating the rise time of the pulses is not

 

common. Slow pulse is set by the command PULS:SLEW MAX. Any

 

value above 1.8 ~1s is set to maximum. The *RST setting is MIN.

.PULM:SLEW:AUTO ONlOFFlllO

•PULM:SLEW:AUTO?

Sets and queries the automatic setting of rise time for the pulse modulation system. The *RST setting is ON.

•PULM:SOURce INTernallEXTernallSCALar

•PULM:SOURce?

Sets and queries the source for the pulse modulation control signal. *RST value is INTernal.

•PULM:STATe ONlOFFlllO a PULM:STATe?

Sets and queries the state of pulse modulation. The *RST value is 0.

•ROSCillator:SOURce?

•ROSCillator:SOURce INTernallEXTernallNONE

 

Sets and queries the reference oscillator selection switch. The
