User’s Manual
Basic Pulse Mode operation
NOTE The following procedure assumes that the Model 2430 is already connected to
the DUT as explained in
Section 2 .
WARNING Hazardous voltages (>30V rms) can appear on the selected INPUT/
OUTPUT LO terminal when performing fast pulse operations. To
eliminate this shock hazard, connect the LO terminal to earth ground.
If using the front panel terminals, ground the front panel LO terminal.
If using the rear panel terminals, ground the rear panel LO terminal.
The ground connection can be made at the chassis ground screw on the
rear panel or to a known safety earth ground.
Front panel pulse-measure procedure
NOTE The following procedure assumes that you are already familiar with Section 3 ,
“ Basic source-measure procedure .”
Step 1: Select Pulse Mode, and set pulse width and pulse delay.
Press CONFIG SOURCE V or I to display source/pulse configuration menu. From the
SHAPE menu item, select PULSE and press ENTER. Pulse width and pulse delay can
then be set from the PULSE WIDTH and DELAY items of the menu. When finished, press
EXIT to return to the normal display. For details, see
“Pulse Mode configuration,”
page 5-10 .
NOTE The source field on the display will read Vpls or Ipls to indicate that the Pulse
Mode is selected.
Step 2: Set pulse measurement speed.
Available speed settings (0.004 to 0.100 PLC) are displayed by pressing SPEED. Select
the desired speed and press ENTER.
Step 3: Set pulse count.
Arm count and trigger count determine how many pulses will be sourced. For finite count
values, the pulse count is the product of the arm count and trigger count. With the arm
count set to infinite, the Model 2430 will continuously output pulses.
Arm and trigger counts are set from the trigger configuration menu which is displayed by
pressing CONFIG and then TRIG. Arm count is set from the ARM LAYER menu item and
trigger count is set from the TRIG LAYER menu item. See “
Front panel Pulse Mode con-
figuration ”, and “Set pulse count,” page 5-10 , for details.
