5.1.6.3
Current measurement - indirect, via shunt resistor
The circuit is closed or opened through the relay. The voltage drop on the shunt resis-
tor is measured with a voltmeter via the R&S analog bus. The current can be calcula-
ted from the voltage and the value of the shunt. The second relay contact is used to
eliminate the measurement error caused by the resistance of the switching contact.

5.1.6.4
Current measurement - direct, up to 1 A
The current is measured directly with a current measurement device via the analog
bus.

Multiplexer - test object signals
Up to four test object signals can be multiplexed to a single local bus. If necessary, the
local bus can be connected with up to three additional local buses or with the global
R&S analog bus.
