:PULSe [1 / 2 / n]
Subsystem. Contains commands to control the
output pulse generation. Valid suffix range
depends on the number of channels (ChA = 1,
ChB = 2, etc). Command without suffix refers to
the currently selected logical instrument. See
INSTrument subsystem.
:OUTPut
Subsystem. Contains command to control
output mode.
:MODe
HIZ / LOZ
Selects output Amplitude mode: High
Impedance or Low Impedance
:AMP
4 V
– 45 V
Sets adjustable output level.
:MERRor
1
Command clears the last module error to allow
the unit to generate pulses again. Query
returns the last displayed error.
