Test Signal
Frequency
75 kHz to 30 MHz, 100 Hz solution
Frequency accuracy
±0.01%
Signal modes
Normal—Program selected voltage or current at the
measurement terminals when they are opened or
shorted, respectively
Constant—Maintains selected voltage or current at
the device under test (DUT) independent of
changes in the device’s impedance.
Signal level
The following test signal level accuracy is specified
for an ambient temperature range of 23 °C ± 5 °C
and the test cable length is 0 m.

For the temperature range of 0 °C to 55 °C, multi-
ply the temperature induced setting error listed in
Figure 1-5 to the test signal setting accuracy. When
test cable length is 1 m or 2 m, add the following
error due to test cable length.
