SW Square Wave Pulsing
Description
This command is used to turn on and off Square Wave pulsing. It
functions exactly the same as the WF command with all the same
forms. This is done to provide compatibility with other model types.
Supplying the optional parameter sets the number of pulses that will
be generated. The load will automatically return to the base drive
level when the set number of pulses has completed.
Command Syntax
SW [<NR1>]
SW OFF
Example
SW
This will turn on Square Wave pulsing until explicitly turned off.
SW 50
This will turn on Square Wave pulsing for 50 pulses and then return
to the base drive level.
SW OFF
This will turn off Square Wave pulsing.
Query Syntax
NONE
Returned Parameters NONE
T1 Pulsing Base Time
Description
This command is used to directly set the base time in microseconds
for square wave pulsing. This will also set the Duty Cycle (DU) and
Frequency (FQ) accordingly based upon the Pulsing Peak Time
(T2).
Command Syntax
T1 <NR1>
Example
T1 2000
This will set the pulse base time to 2000
µ
s. If T2 were 3000
µ
s, the
duty cycle (DU) would be 60% and frequency would be 200Hz.
Query Syntax
T1?
