Remote Operation
OUTPut:RECOrder:FAST
Description:
Set or return the state of the recorder “fast mode” setting. OFF is the instrument’s power-
on default setting, and uses standard recorder output speed (about 50ms). Display and
other functions including bus operation have priority over recorder output update. ON
enables a special, high-speed recorder output mode. This mode gives priority to updating
the recorder output, and should only be used where the absolute, fastest recorder output
response is required. Latency will be under 10ms in Modulated Mode. Note that display
update speed and bus response may be slowed.
Syntax:
OUTPut:RECOrder:FAST <asc>
Argument:
<asc> = OFF, ON
Valid Modes:
Any
OUTPut:RECOrder:CALibration:SLOPe
Description:
Adjusts the slope, or gain of the recorder output. This command is typically used with a
recorder Zero Adj command to calibrate the recorder output for maximum absolute accu-
racy. The setting represents the deviation in percent from the factory default slope value,
and may be adjusted in 0.01% increments, corresponding to 1mV at fullscale, although
actual output resolution is 5mV. Changing the slope “pivots” the curve around the 0.0 volt
setting, and will have maximum effect at -10.0 volts and +10.0 volts. Note that this setting
is not permanent unless “Save Cal” is used.
Syntax:
OUTPut:RECOrder:CALibration:SLOPe <n>
Argument:
<n> = -10.0 to +10.0 %
Valid Modes:
Any
OUTPut:RECOrder:CALibration:ZERO
Description:
Adjusts the zero, or voltage offset of the recorder output. This command is typically used
with a recorder Slope Adj command to calibrate the recorder output for maximum absolute
accuracy. The setting increases or decreases the actual output voltage by a fixed amount,
and may be adjusted in 1mV increments, although actual output resolution is 5mV. Chang-
ing the offset moves the entire curve up or down, and has equal effect at all output levels.
Note that this setting is not permanent unless “Save Cal” is used.
Syntax:
OUTPut:RECOrder:CALibration:ZERO <n>
Argument:
<n> = -1.000 to +1.000 V
Valid Modes:
Any
OUTPut:RECOrder:CALibration:SAVE
Description:
Saves the recorder Zero and Slope adjustments to the instrument’s non-volatile calibration
memory once they have been set. If this step is not performed, the settings will revert back
to the previous settings next time instrument power is applied.
Syntax:
OUTPut:RECOrder:CALibration:SAVE
Argument:
None
Valid Modes:
Any
