SC600 Oscilloscope Calibration Option
Remote Commands and Queries

9-29
Do the subsequent procedure to verify the overload protection of an oscilloscope:
1.
Connect the Calibrator to Channel 1 on the oscilloscope.
2. Select the voltage type (DC or AC) with the OUT VAL softkey.
3. Key in the voltage level. (The default value is 5 V.)
4. If necessary, change the time. (Refer to the procedure given above.) The default time
is 10s.
5. Look for test results shown with the UUTTRIP softkey.
Remote Commands and Queries
This section tells you commands and queries that are exclusive to the SC600 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 Each command and query has a check
box that shows applicability to IEEE-488 (general purpose interface bus, or GPIB) and
RS-232 remote operations.
Sequential Commands Commands done immediately as they are found in the data
stream are referred to as sequential commands. For more information, see “Sequential
Commands” in Chapter 5.
Overlapped Commands Commands
SCOPE
,
TRIG
, and
OUT_IMP
are designated as
overlapped commands because they can be overlapped (interrupted) by the subsequent
command before they have completed execution. When an overlapped command is
interrupted, it can take longer to do while it stops for other commands to be completed.
To prevent an overlapped command interruption during execution, use
*OPC
,
*OPC?
, or
*WAI
, which prevent interruptions until they sense command completion. For more
information, see “Overlapped Commands” in Chapter 5.
Coupled Commands
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
disable each other, since a fault can be the result. For more information, see “Coupled
Commands” in Chapter 5.
General Commands
Table 9-1 is a list of Scope command parameters.
Table 9-1. SCOPE Command Parameters
Parameter Description/Example
OFF
Turns the oscilloscope hardware off. Programs 0 V, 0 Hz, output at the NORMAL
terminals, standby.
VOLT
Oscilloscope ac and dc VOLT mode. Programs 20 mV peak-to-peak, 1 kHz, output at
the SCOPE BNC, output impedance 1 M
Ω
, standby if from OFF or if in standby.
FUNC? Shows SACV (for ac) or SDCV (for dc).
Example: SCOPE VOLT; OUT 4 V, 1 kHz
(ac voltage, 4 V peak-to-peak, 1 kHz.)
