MOD

The LDX-32420 allows a modulated voltage signal to be
superimposed on the current source output. The input for
this signal is a BNC located in the MOD section labeled
External. This port is configured as a differential input
allowing the shell to be grounded through the connecting
instrument. The input impedance is 1 K. The voltage to
current transfer function depends on the range of the
instrument and is specified just below the BNC connector
as shown.
