Specifications

Introduction

Table A-1 lists the specifications of the dc source. Unless otherwise noted, specifications are warranted at 25°C ± 5°C after a 30-minute warm-up period. Sense terminals must be connected to their respective output terminals.

1Voltage accuracy specification in voltage priority mode guaranteed between –10.25V to +10.25V. 0.5A current range accuracy specification in voltage priority mode guaranteed between –0.5125A and +0.5125A. Readback for Voltage, 0.5A, and 15mA current ranges is based on capturing 5 data points at intervals of 30.4∝s and averaging the readings. Readback for 0.5mA current range is based on averaging the readings over 1 power line cycle (60 Hz = 548 points @ 30.4∝s). The default setting for all readback ranges is the average of 5 data points 30.4∝s apart.

2Program Vset to ±10V using a 20 ohm load resistor.

3Program current to +500mA using a 20 ohm load resistor. Program Vset to ±10.25V.

4Program current to ±0.5mA using a 16K ohm load resistor.

5Measured with a 10uF output capacitor with 0.2 ohm ESR across the output with the current limit set to +0.5125A. The load current rise time is approximately 10us for a current change of 0.25Ato 0.5A or 0.5A to 0.25A. Measure the output voltage recovery time to within 40mV of its final value.

6Measured following a voltage change of –1V to +1V or +1V to –1V with approximately 25us time constant with the current priority current level set to 0uA. Measure the output current recovery time to within ±1mA of its final value.
