2. To change the front panel time interval and buffer size for output waveform
measurements, press Shift, Input. Then press q until you obtain the TINT
command. Use the Entry keys to enter a value from 15.6 microseconds to 1
second in seconds. Then press Enter.
TINT 0.002

Continue by pressing Shift, Input and q until you obtain the POINT command.
Press ä to select a different buffer size. The choices are: 1, 2, 4, 8, 16, 32, 64,
128, 256, 512, 1024, and 2048. Then press Enter.
One reason to change the front panel time interval and data points is if the
waveform being measured has a period shorter than 3 times the present front
panel acquisition time.

For current measurements, press Shift, Input. Then press ä until you obtain the
CURR:RANG AUTO command. Press Enter to activate autoranging. Two other
selections are also available. Select the HIGH range when measuring currents
above 20 mA. Select the LOW range for improved resolution when measuring
currents below 20 mA. Note that the LOW range is only appropriate for making
dc measurements.

For output waveform measurements, press Shift, Input. Then press q until you
obtain the CURR:DET command. Check to make sure that the ACDC current
detector is selected. This provides the best accuracy for waveform measurements.
Only select the DC current detector if you are making dc current measurements
and you require a dc measurement offset better than 2mA on the High current
measurement range. Press Enter to activate any changes.

NOTE: In the LOW current measurement range, the current detector is fixed at DC. With the
current detector in dc, accurate current measurements cannot be made on waveforms
with frequency contents over 1 kilohertz.
