Current Measurement Configuration - Agilent Technologies 34972A User Manual

Current Measurement Configuration

To connect a current source to the module's screw terminals, see page 28.
This section contains information to help you configure the instrument
for making current measurements on the 34901A multiplexer module.
This module has two fused channels for direct DC and AC current
measurements on the measurement ranges shown below.
10 mA 100 mA
Note: Current measurements are allowed only on channels 21 and 22 on
the 34901A module.
AC Low Frequency Filter
The instrument uses three different AC filters which enable you to either
optimize low frequency accuracy or achieve faster AC settling times. The
instrument selects the slow, medium, or fast filter based on the input
frequency that you specify for the selected channels.
Applies to AC current and AC voltage measurements only.
Input Frequency
3 Hz to 300 kHz (Slow)
20Hz to 300 KHz (Medium)
200 Hz to 300 kHz (Fast)
• The instrument selects the medium filter (20 Hz) when the function is
changed or after a Factory Reset (*RST command). An Instrument
Preset (SYSTem:PRESet command) or Card Reset (SYSTem:CPON
command) does not change the setting.
