3-30 Measurements and Sourcing Voltage
E) OHMS:AVOLtage:POINts?
This query returns the number of points per phase based on the user-supplied TIME value
above. If the number of points would be greater than the maximum of 1,000 (for example,
if you had set a new integration rate but not yet changed the AVOL:TIME value), then
-999 will be returned. A -999 return value indicates that you cannot send the
OHMS:AVOL:ARM command until you adjust either the time interval or the integration
rate to obtain a valid number of points.
F) OHMS:AVOLtage:ONEShot <b>
This command controls the one-shot A-V ohms mode. If the one-shot mode is ON, then
only a single reading is collected for each voltage phase at the end of the TIME interval
given above.
G) OHMS:AVOLtage:CYCLes <NRf>
This command sets the number of cycles to run A-V ohms. A cycle is defined as one
V-High and one V-Zero step.
H) OHMS:AVOLtage:UNITs <name>
This command sets the units that the A-V ohms readings will be stored and returned in,
amps or ohms.
I)
CLE manually clears the A-V ohms buffers. TRAC:CLEar will also do the same thing.
AUTO ON enables A-V ohms auto-clear. If enabled, arming the next A-V ohms run will
clear out the buffers. If disabled, subsequent A-V ohms runs will get averaged in with the
saved readings.
J)
This query returns the number of V-High/V-Low cycles that have been averaged to result
in the data stored in the A-V ohms buffer.
K) TRACe:DATA? [BUFFER]
This query returns data either from the normal buffer or the A-V ohms buffer. If A-V ohms
is not on and no A-V ohms readings have been collected, normal buffer readings will be
returned. If A-V ohms readings have been collected, A-V ohms readings will be returned.
L) TRACe:MODE?
This query returns the type of data stored in the buffer (either DC or AVOLtage).
OHMS:AVOLtage:CLEar
OHMS:AVOLtage:BCOunt?
