Introduction to Programming
Initialization
Initialization
To make sure the bus and all appropriate interfaces are in a known state, begin
every program with an initialization statement. For example, HP BASIC
provides a CLEAR command which clears the interface buffer:
CLEAR 707 ! initializes the interface of the oscilloscope
When you are using GPIB, CLEAR also resets the oscilloscope's parser. The
parser is the program that reads in the instructions you send.
After clearing the interface, initialize the oscilloscope to a preset state:
OUTPUT 707;"*RST" ! initializes the oscilloscope to a preset
state
Autoscale
The AUTOSCALE feature of Agilent Technologies digitizing oscilloscopes
performs a very useful function on unknown waveforms by automatically setting
up the vertical channel, time base, and trigger level of the oscilloscope.
The syntax for the autoscale function is:
:AUTOSCALE<terminator>
Setting Up the Oscilloscope
A typical oscilloscope setup configures the vertical range and offset voltage, the
horizontal range, delay time, delay reference, trigger mode, trigger level, and
slope.
A typical example of the commands sent to the oscilloscope are:
:CHANNEL1:PROBE 10; RANGE 16;OFFSET 1.00<terminator>
:SYSTEM:HEADER OFF<terminator>
:TIMEBASE:RANGE 1E-3;DELAY 100E-6<terminator>
This example sets the time base at 1 ms full-scale (100
µ
s/div), with delay of
100
µ
s. Vertical is set to 16 V full-scale (2 V/div), with center of screen at 1 V,
and probe attenuation of 10.
Initializing the Oscilloscope
The commands and syntax for initializing the oscilloscope are discussed in the
chapter, “Common Commands.” Refer to your GPIB manual and programming
language reference manual for information on initializing the interface.
