V Output Indicator
The V output indicator indicates that the test voltage is applied to the DUT .
Source V oltage key
The source voltage key sets the test voltage value from 0 to 1000 V . Resolution of the test
voltage is as follows:
V oltage Range Resolution
0 V T est V oltage 200 V 0.1 V
200 V < T est V oltage 1000 V 1 V
Current Limit K ey
The current limit key sets the limitation value of current owing through the DUT . The
4339B adjusts the test voltage so that the current owing through the DUT does not exceed
the current limit value . While the current limit is active and the source output is decreased,
the 4339B displays \OVER CURRENT ". The current limitation feature protects the DUT from
destruction due to high current ow . Current limits can be set to the following values:
0.5 mA (default)
1 mA
2 mA (at test voltage 0 to 500 V only)
5 mA (at test voltage 0 to 250 V only)
10 mA (at test voltage 0 to 100 V only)
Note
When the 16117B Low Noise T est Leads are used, the available current limit
setting is 0.5 mA only .
Measurement Time key
The measurement time key sets measurement time mode: Short, Medium(Med ), or Long.
A longer measurement time produces a more accurate measurement result. The current
measurement time mode setting is indicated by the Meas Time annunciator( 9 ). The default
setting is Medium.
A verage key
The average key sets the measurement averaging rate . The 4339B automatically averages the
measurement results by this rate . The averaging rate can be set as an integer from 1 to 256.
The default setting is 1.
