**Performance Characteristics:**
* **Dynamic Loading:** Capable of dynamic loading with speeds up to 20 kHz. The programmable slew rate allows for the simulation of transient load changes.
* **Slew Rate:** Fast response with slew rates ranging from 0.32 mA/µs to 10 A/µs.
* **Transient Response:** Capable of real-time power supply load transient response simulation.
* **Minimum Input Resistance:** Designed to sink high current even at very low voltages.
* **Current/Voltage Measurement Accuracy:**
* Voltage Measurement: ±0.025% of full scale + ±0.025% (Note: Some sources indicate 15-bit precision with accuracy of 0.05% + 0.05% full scale for the 6310 series, while others mention 16-bit precision with accuracy of 0.025%+0.025% of full scale for the 63101A).
* Current Measurement: ±0.05% of full scale + ±0.05% (Note: Some sources indicate 0.1% + 0.1% full scale for the 6310 series).
* **Measurement Resolution:** 16-bit precision voltage and current measurement with dual-range capability.
**Features:**
* **Parallel Operation:** Load modules can be paralleled for increased current and power handling capabilities, up to 1200W in total within a mainframe. Modules can be configured to work synchronously for testing multiple outputs simultaneously.
* **Programmable Sequences:** User programmable up to 100 sequences for automated testing applications.
* **Timing Function:** Precise time measurements from 1ms to 86,400s, useful for battery discharge testing and other applications.
* **Short Circuit Simulation:** Capability to simulate short circuit conditions.
* **Front Panel Operation:** User-friendly keypad for front panel operation and status indication.
* **Test Limits:** High/Low limits for testing parameters to determine GO/NG status.
* **Self-Test:** Self-test function upon power-on.
* **Remote Sensing:** Utilizes remote sensing to eliminate voltage drop errors.
**Protection Features:**
* **Full Protection:** Over Voltage (OV), Over Current (OC), Over Power (OP), Over Temperature (OT), and reverse polarity protection.
**Interfaces:**
* **Mainframe Dependent:** USB, GPIB & RS-232 interface connectivity is dependent on the mainframe used. The 6310 series can use either GPIB or RS232C, but not simultaneously.
**Physical:**
* **Module Design:** Designed as a module to be inserted into a mainframe.
