Pulse Current Measurements 3-7
• AUTO TIME — Use to automatically set the integration times for high, low, and average
pulse-current measurements. These times are based on detecting the pulse and remain
until another auto time is performed or the times are manually changed. Auto time
accounts for the internal (15μsec) delay but not the user trigger delay.
NOTE Do
not use AUTO TIME with the Model 2306-VS if the other channel has trigger
external enabled.
• PUL
SE TIMEOUT — Use to set the variable pulse current timeout feature for pulse
current measurements. The default value is 1.000 second (incremented in 1ms steps).
Refer to "Using FAST, SEARch, and DETect" for detailed usage information on
properly setting this TimeOUT variable.
Average readings count
Use the AVERAGE READINGS item of the PULSE CURRENT #1/#2 menu item to set the
average readings count. This count specifies the number of measurements (integrations) to aver-
age for each reading. For example, with measureme
nt count set to 10, each displayed reading
will reflect the average of 10 pulse current measurements. Each measurement needs to start after
detecting the respective edge for triggering.
NOTE Set A
VERAGE READINGS count in the range of 1 to 100.
Trigger delay, trigger level range, and trigger level
Use the following items of the PULSE CURRENT menu item to set trigger delay, trigger
level range, and trigger level:
• TRIGGER DELA
Y — Use to specify additional user trigger delay (0 to 100msec in
10µsec steps). See“Trigger delay” on page 3-3 for details. This user trigger delay is in
addition to the internal trigger delay of 15µsec.
• TRG LEV mA
Range — Model 2306-PJ battery channel only setting. Use to specify the
trigger level range resolution. Possible ranges are:
Model 2306-PJ (500mA current range only)
500mA FULL SCALE (0-500mA)
100mA FULL SCALE (0-100mA)
10mA FULL SCALE (0-10mA)
