SCPI COMMAND SUMMARY
PULM:INTernal:PERiod <num>[time suffix]|MAXimum|MINimum
PULM:INTernal:PERiod? {MAXimum|MINimum]
Sets and queries the perio d of the internal pulse generator.
The *RST value is 2
s.
PULM:INTernal:TRIGger:SOURce INTernal|EXTernal
PULM:INTernal:TRIGger:SOURce? [MAXimum|MINimum]
Sets and queries the setting of the internal pulse generator's trigger
source. When INTernal, pulse p erio d and frequency determine the
repetition rate of the pulse train. When in EXTernal, the repetition
rate is set by the EXT PULSE in jack. After *RST, the value is
INTernal.
PULM:INTernal:WIDTH <num>{time suffix]|MAXimum|MINimum
PULM:INTernal:WIDTH? [MAXimum|MINimum]
Sets and queries the width of the internal pulse generator. The *RST
value is 1
s.
Pulse Subsystem
Since frequency and p erio d are in
versely related, if b oth 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 <num>[freq suffix]|MAXimum|MINimum
PULSe:FREQuency? [MAXimum|MINimum]
Sets and queries the frequency of the internal pulse generator. The
resolution of the frequency is such that the resulting perio d is set to a
resolution of 1
s. The *RST value is 500 kHz.
PULSe:PERiod <num>[time suffix]|MAXimum|MINimum
PULSe:PERiod? [MAXimum|MINimum]
Sets and queries the perio d of the internal pulse generator. The
resolution of this is 1
s. The *RST value is 2
s.
PULSe:WIDTh <num>[time suffix]|MAXimum|MINimum
PULSe:WIDTh? [MAXimum|MINimum]
Sets and queries the width of the internal pulse generator. The *RST
value is 1
s.
PULM:SLEW <num>[time suffix]|MAXimum|MINimum
PULM:SLEW? [MAXimum|MINimum]
Sets and queries the rise time for the pulse mo dulation. The typical
usage is
MAX|MIN
since calibrating the rise time of the pulses is not
common. Slow pulse is set by the command
PULS:SLEW MAX
.Any
value ab ove 1.8
s is set to maximum. The *RST setting is
MIN
.
