4-20 Sweeps Model 6220/6221 Reference Manual
Return to Section 4 topics
1.0E-13, and Error +420 Log sweep zero adjusted will be issued. Note that
start or stop values are not restored back to zero if the SPACing is subse-
quently changed back to LINear, so make sure the start and stop values are
correct after sending the SOUR:SPACing command.
When the sweep is armed with the ARM command, an internal sweep table of
output DAC values is processed. During this build, the unit cannot respond to
key presses or remote commands. If there are more than 3,000 points in the
sweep table, the message “Building Sweep table Please wait.....” is shown on
the display and remains until the sweep table is built. A 10,000 point sweep
will require about eight seconds to build.
5. SOUR:SWE:ABOR ‘ Abort sweep immediately
Terminates any sweep in progress and sets the source value to zero and the
operate state to OFF. Starting another sweep after the SOUR:SWEep:ABORt
command will require re-arming. Note that this command is also used to exit
Differential Conductance or Delta mode and resume normal current source
operation.
6. SOUR:SWE:SPAC <name> ‘ Select sweep type
This command chooses the LINear staircase, LOGarithmic staircase, or LIST
(custom) sweep type. See Table 4-5 and following notes for details on custom
sweep commands.
7. SOUR:SWE:POIN <n> ‘ Set sweep points
Use this command to set the number of sweep points for staircase sweeps
(65,535 maximum). The number of points in a custom sweep is determined by
the LIST parameters (see Table 4-5).
8. SOUR:SWE:RANG <name> ‘ Set source ranging for sweeps
Selects how the source range will be handled with sweeps. AUTO selects the
best source range at each point, and FIXed leaves the source at the range the
unit was on when the sweep started (Error -221 Settings Conflict will occur if
the sweep is started from a source range that is too low). BEST causes the
source range to be set to the correct range for the highest point in the sweep.
9. SOUR:SWE:CAB <b> ‘ Abort sweep on compliance
When set to ON, terminates any sweep in progress when compliance is
detected during a sweep. The source value is set to zero, and the operate
state is set to OFF.
10. SOUR:SWE:COUN <n> ‘ Set sweep count
Use this command to set the number of sweeps to run. An INFinite sweep
count will select continuously repeating sweeps.
