SC300 Oscilloscope Calibration Option
Summary of Commands and Queries
10
10-25
Each option in the Wavegen menu is given below.
•
OUTPUT @ SCOPE Shows the location of the signal output. If the signal does not
show on the oscilloscope, push

. To disconnect the signal, push

.
•
WAVE Moves through the three types of waveforms that are available. You can
select a square, sine, or triangle wave as the output.
•
SCOPE Z Toggles the output impedance setting of the Calibrator between 50
Ω
and
1 M
Ω
.
•
OFFSET Shows the offset of the generated wave. To change the offset, key in the
new value, and push

. The rotary knob does not change the offset, it changes
the actual voltage output.
When you change the offset, you must stay between specified limits to prevent
clipping the peaks. The limit depends on the p-p value of the wave. The maximum
peak excursion is equal to the offset plus half of the p-p value of the wave. See
“Wave Generator Specifications” in this chapter.
•
MODE Shows that you are in Wavegen mode. Use the softkey to change modes and
open the related menus for the other four oscilloscope calibration modes.
Summary of Commands and Queries
This section tells you about commands and queries that are used only for the oscilloscope
calibration option. Each command description shows if it can be used with IEEE-488 and
RS-232 remote interfaces and identifies it as a Sequential, Overlapped, or Coupled
command.
IEEE-488 (GPIB) and RS-232 Applicability
IEEE-488 RS-232
x x
Each
command and query have a check box that shows applicability to IEEE-488 (general
purpose interface bus, or GPIB) and RS-232 remote operations.
Sequential Commands
Sequential
x
Commands done immediately as occur in
the data stream are named sequential commands. For more information, see “Sequential
Commands” in Chapter 5.
Overlapped Commands
Overlapped
x
Commands
SCOPE
,
TRIG
, and
OUT_IMP
are overlapped commands because they can be overlapped (interrupted) by the
subsequent command before they are complete. When an overlapped command is
interrupted, it can take longer to do the command while it stops for other commands to
complete. To prevent an overlapped command from interruption during execution, use
*OPC
,
*OPC?
, or
*WAI.
These commands prevent interruptions until they sense that
the command is complete. For more information, see “Overlapped Commands” in
Chapter 5.
Coupled Commands
Coupled
x
SCOPE
and
OUT
_
IMP
are coupled commands
because they can be coupled (combined) with other commands to make a compound
command sequence. Precautions are necessary to make sure that commands are not
coupled so that they can cause them to disable each other, since this can end in a fault.
For more information, see “Coupled Commands” in Chapter 5.
