HP-IB Interface Capabilities:

SH1, AH1, T6, L4, SR1, RL1, PP1, DC1, DT0, C0, E1

Current Sink Capability:

Current sink limits are fixed approximately 10% higher than the maximum current source limits for a given operating voltage at any voltage above 2.5 V (see Chapter 4).

Command Processing Time: (see Figure 1-3):

7 milliseconds typical (with front panel display disabled). Using STO and RCL commands allows you to change all the voltage and current settings in about 10 mS (with front panel display disabled).

Series and Parallel Operation:

Two outputs can be operated directly in parallel or can be connected for straight series operation. Refer to Chapter 4 for more information.

Reactive Load Capability:

All outputs have been designed with the ability to operate with significant reactive loads without instability (refer to Figures 1-4 through 1-6).
