At any time, you can also set the overload time limit with
S
, INSTMT SETUP
softkey, OTHER SETUP softkey, TLIMDEF softkey, and then choose 1s to 60 s.
Perform the following procedure to test the overload protection of an oscilloscope:
1.
Connect the calibrator to Channel 1 on the oscilloscope.
2. Select the voltage type (DC or AC) using the OUT VAL softkey.
3. Key in the voltage level. (The default value is 5 V.)
4. If necessary, change the duration. (Refer to the procedure described above.) The
default duration is 10s.
5. Check for test results displayed with the UUTTRIP softkey.
Remote Commands and Queries
This section describes commands and queries that are used specifically for the SC1100
Option. Each command description indicates whether 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 indicating applicability to IEEE-488 (general purpose interface bus, or GPIB) and
RS-232 remote operations.
Sequential Commands Commands executed immediately as they are encountered in the
data stream are called 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 may be overlapped (interrupted) by the next
command before they have completed execution. When an overlapped command is
interrupted, it may take longer to execute while it waits for other commands to be
completed. To prevent an overlapped command from being interrupted during execution,
use
*OPC, *OPC?
, or
*WAI
. These commands prevent interruptions until they detect
the command’s 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 form a compound command sequence.
Care must be taken to ensure that commands are not coupled in a way that may cause
them to disable each other, since this may result in a fault. For more information, see
“Coupled Commands” in Chapter 5.
General Commands
Table 10-1 is a list of Scope command parameters.
Table 10-1. 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 previously in
standby. FUNC? returns SACV (for ac) or SDCV (for dc).
Example: SCOPE VOLT; OUT 4 V, 1 kHz
(ac voltage, 4 V peak-to-peak, 1 kHz.)
