Analog Programming (APG) and Isolated Analog Programming (ISOL)

Introduction

The rear panel connectors J1 and J3 provide an option to control and monitor the output of the power supply with analog signals. Connector J1 provides a non-isolated analog interface where all signals are referenced to the negative output terminal of the power supply. Connector J3 is an isolated interface and also provides an isolated auxiliary voltage output to aid analog programming.

Analog Programming (APG) of Output Voltage and Output Current

Analog programming allows control of the power supply’s output voltage, output current or both to be controlled from analog input sources. As the programming source is varied within the configured analog programming range (2–10 volts/kΩ max), the power supply’s output varies proportionally over its output range. For example, if you set the programming scale to 10 V voltage source and apply 5 V to the programming pins, the power supply will be programmed to 50% of the output capability for your power supply.

While analog programming mode is configured, you will not be able to make adjustments to the set points from the front panel or through the remote interfaces.

The front panel will display AnPr in the output current display when the 9-position mode control is turned to VOLTS or AMPS positions for the parameter(s) that are configured to be controlled by analog programming. If an adjustment of a parameter controlled by APG is attempted using a SCPI command, a “-221 Settings Conflict” error will be pushed onto the error queue.

Using analog programming requires that you make connections to the Isolated Analog Programming Connector or Analog Programming Connector on the rear panel of the power supply. Depending on your model, see “Rear Panel Connectors” on page 1–6 or “” on page 1–7.
