Setting the Channel Timing Parameters
To define a pulse requires three parameters: The sync source, the delay to the
active edge, and the width of the pulse. Although each channel receives its start
pulse from the internal T
0
pulse, logically the start pulse can be assigned such
that the delay entered is relative to the T
0
pulse or any other channel pulse.
This allows dependent events to link. The unit will not allow a circular chain of
sync sources that would result in a channel triggering itself. The delay entered
is relative to the selected sync source.
Sync Source: Selects the channel sync source.
Wid: Sets the channel pulsewidth.
Dly: Sets the channel delay until the active edge.
Setting Pulse Output Configuration
The 9500+ supports two types of outputs: a high speed TTL/CMOS compatible
output; and, for applications which require different voltage levels or higher
current, an adjustable voltage output. The pulses can also be defined to be
active high or active low.
Pol: Sets the pulse polarity, active high or active low. Out:
Selects the output mode, TTL/CMOS or Adjustable
Ampl: Sets the output voltage level (unloaded) when in the
Adjustable mode.
Setting Pulse Mode of Operation
Each channel may be set independently to operate in one of four modes: normal,
single shot, burst, or duty cycle (within the CHANNEL menus):
• Mode: Selects the mode for the current channel. Additional
parameters are provided for the burst mode and the
duty cycle mode.
• Burst: Sets the number of pulses in the burst mode to
generate before inhibiting output.
• On: Sets the number of pulses to generate before inhibiting
output in Duty Cycle Mode.
• Off: Sets the number of pulses to inhibit before repeating
the On Cycle in Duty Cycle Mode.
Setting Pulse Gate Control
Enables the use of the external input to gate the channel output (within the
CHANNEL menu):
• Gate: Enables/disables the channel gating using the EXT/
GATE input.
