Initialization
To make sure the bus and all appropriate interfaces are in a known state,
begin every program with an initialization statement. HP BASIC provides a
CLEAR command which clears the interface buffer:
CLEAR 707 ! initializes the interface of the instrument
When you are using HP-IB, CLEAR also resets the oscilloscope’s parser. The
parser is the program which reads in the instructions which you send it.
After clearing the interface, initialize the instrument to a preset state:
OUTPUT 707;"*RST" ! initializes the instrument to a preset
state.
Information for Initializing the Instrument
The actual commands and syntax for initializing the instrument are discussed in
the common commands section of the online
HP 54645A/D Oscilloscopes
Programmer’s Reference
.
Refer to your controller manual and programming language reference manual
for information on initializing the interface.
