Programming the 16533/34A Oscilloscope Module
Selecting the Module
Selecting the Module
Before you can program the oscilloscope, you must first "select" it, otherwise,
there is no way to direct your commands to the oscilloscope.
To select the module, use the system command :SELect followed by the
numeric reference for the slot location of the oscilloscope (1...10 refers to
slot A...J respectively). For example, if the oscilloscope card is in slot E, then
the command:
:SELect 5
would select this module. For a multi-card configuration you would select
the topmost card slot of the multi-card configuration. For more information
on the select command, refer to the Agilent Technologies 16500B/16501A
Programmer's Guide.
Setting up an Oscilloscope
The easiest and fastest way to set up the oscilloscope is to use the
AUTOSCALE command. The AUTOSCALE command causes the
oscilloscope to automatically select the vertical sensitivity, vertical offset,
trigger source, trigger level and timebase settings for optimum viewing of any
input signals. The trigger source is the lowest channel on which the trigger
was found. If no signal is found, the oscilloscope defaults to auto-trigger.
To demonstrate a quick oscilloscope setup, we will use the AC CAL signal
available at the rear panel of the card. This square wave is normally used for
calibration and probe compensation.
Connect the CAL OUTPUT signal from the rear panel output connector to
CHAN 1, also on the rear panel. Ensure that the mainframe is connected to a
controller. Enter the program listed on the next page and execute it.
