TOGGLE MODE: In toggle mode, the PEL input alternates between two user-defined input levels. Unlike transient-continuous mode, the input only changes from one level to another, one transition at a time. Transient Level Main Level Toggle t Typical Application: Testing the transient recovery time for a CV power supply. The recovery time for a power supply is defined as the time required for the supply to settle to a predefined settling band following a change in load current caused by an induced transient (pulse). LCL Operation: • From keypad select operating mode (CC, CV, CR, CP) • Select transient operation for toggle mode. • Set MAIN and TRANSIENT levels by pressing the “MAIN” and “TRANS” keys. • To begin the toggle operation, turn on the input and press the “TR ON/OFF. The LCD will display a flashing “TG” to indicate that the PEL is in toggle mode. All the operating modes can be programmed via the front panel or by way of the GPIB/RS232 Interface. In addition, each transient can be triggered through an external TTL compatible signal. 46
FOUR: REMOTE PROGRAMMING INTRODUCTION The Programming Electronic Load is provided with GPIB and RS-232 Standard Commands for Programmable Instruments (SCPI) interface for automated testing applications. The purpose of this section is to introduce the user to SCPI commands used to control the PEL via remote communication. INTRODUCTION TO GPIB & RS-232 (SCPI) COMMANDS The General Purpose Interface bus is synonymous with HP-IB standard bus used for controlling electronic instruments with a computer. Also called IEEE 488 bus because ANSI/IEEE Standards 488-1978 defines it, 488.1-1987, and 488.2-1987. Standard Commands for Programmable Instruments (SCPI) is a programming language developed to remotely control different test and measurement instruments over GPIB (IEEE 488) bus. SCPI functions with GPIB hardware conform to the IEEE 488.2 Standard Digital Interface for Programmable Instrumentation. It is a device independent command set and is layered on top of the hardware portion of IEEE 488.2. SCPI simplifies the programming task by defining a single comprehensive command set of programmable instrumentation, regardless of type or manufacturer. The same SCPI command can be applied to different classes of instruments. SCPI systems are much easier to program and maintain. In many cases, you can interchange or upgrade instruments without having to change the test program. SCPI also applies to RS-232 programming. The electronic load's GPIB address cannot be set via GPIB bus communication or program. The address needs to be set from the front panel keypad in the UTILITY function. 47
