Operation Complete Output Query. This query causes the electronic load to place an ASCII "1" in

the Output Queue when all pending operations are completed. Pending operations are complete

when:

All commands that were issued before an *OPC command have been executed.

Any change in the input level caused by these previous commands has been

completed. (Effects of slew time have been accounted for.)

No pending trigger level operations are set for the single electronic load or for any

channel of the multiple electronic load.

Unlike *OPC, *OPC? prevents processing of all subsequent commands. When all pending operations

are completed, an ASCII "1" is placed in the Output Queue. *OPC? is intended to be used at the end

of a command line so that the program can then monitor the bus for data until it receives the "1" from

the Output Queue.

Command Syntax *OPC?

Returned Parameters <NR1> , ASCII 1 is placed in the Output Queue when the electronic load

has complet

all pending operations.

*PSC

Power-on Status Clear Command/Query. Type Device Initialization Description This command

controls the automatic clearing at power turn-on of:

The Service Request Enable register.

The Standard Event Status Enable register.

If the command parameter = 0, then the electronic load can be programmed to request service at turn

on. Any non-zero parameter causes both registers to be cleared at turn on, preventing the electronic

load from being capable of requesting service at this time.

Command Syntax *PSC <NRf>

Parameters 0 or not zero

Suffix None

Query Syntax *PSC?

Returned Parameters <NR1> 0 = power-on clear flag is false; affe

cted re

gisters not cleared

at turn on.

1 = power-on clear flag is true; affected registers cleared at

turn on.

Suffix None

*RCL

Recall Instrument State Command. This command restores the electronic load to a state that was

previously stored in memory with a *SAV command to the specified location (see *SAV). *RCL also

does the following:

At power turn-on, the equivalent of an *RCL 0 is executed to restore the electronic load to the state

stored in location 0. The same state is also set if the *RCL command is directed to a location where

no state was stored since the last time power was cycled.

Note *RCL does not affect any Status Enable registers or Transition F

ilt

ers.

Command Syntax *RCL <NRf>

Parameters 0 through 3
