Use the Meter menu for making front panel measurements:
Action
1.
For current measurements, press Shift, Input. Then press
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.
2.
For output waveform measurements, press Shift, Input. Then press
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 1mA 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.
3.
To change the front panel time interval and buffer size for output waveform
measurements, press Shift, Input. Then press
command. Use the Entry keys to enter a value from 15.6 microseconds to 1 second
in seconds. Then press Enter.
4.
Continue by pressing Shift, Input and
Press
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.
5.
On the Function keypad press Meter and press
to access the following measurement parameters:
♦
dc voltage and current
♦
peak voltage
♦
minimum voltage
♦
high level of a voltage pulse waveform
