Front Panel Operation

The numeric keys and rotary knob provide a convenient interface for setting output levels quickly and precisely. Voltage and Current can be set to a maximum resolution of 0.5mV (2mV for 9124) and 0.1mA respectively. Up to 50 parameters can be stored and recalled from internal memory.

Remote Interface

The power supplies can be remotely controlled from any PC with USB or RS232 interface, allowing the user to program and monitor all parameters through easy to use SCPI commands. The power supplies come with a RS232 to TTL serial converter cable and a USB to TTL serial converter cable. Additionally, model 9123A can be controlled via GPIB interface and includes a GPIB to TTL conversion adapter cable.

Extra Features

The 9120 series’ digital port offers a variety of configurations. The port can operate in Digital I/O, external Trigger and DFI/RI (Discrete Fault Indicator/Remote Inhibit) mode. The RI feature can be used for turning several power supplies On/Off simultaneously. External triggering can be used in combination with List mode.

The included Application Software supports front panel emulation and allows users to generate simple test sequences without the need to write source code. Additionally, the power supply comes with a built-in 5 1/2 digit DVM and high resolution milliohm meter supporting 4 wire measurements.
