COMMAND REFERENCE
INTRODUCTION
This chapter is a guide to all of the device-dependent commands for the LDX-3200 Series Precision Current Source.
This chapter is divided into two parts. The first part contains an overview of the remote commands used by the
LDX-3200 Series Precision Current Source. The second part contains all of the LDX-3200 Series Precision Current
Source commands in alphabetical order. Figure 4.1 shows the format for the device command descriptions in this
chapter. The commands which emulate local (front panel) operation are denoted by the solid box next to the Local
label in the upper left corner of the command description.
