SAMPle Subsystem

The SAMPle commands are used with the TRIGger commands to set up the triggering parameters. Use the
SAMPle commands to set a sample count, sample source, and delay time for triggered sampling.
It is recommended that all triggered measurements be made using an appropriate fixed
manual range. That is, turn autorange off
a fixed range using the SENSe:<function>:RANGe, CONFigure, or

SAMPle:SOURce
SAMPle:TIMer
SAMPle:COUNt {< count >|MIN|MAX|DEF}
SAMPle:COUNt? [{MIN|MAX|DEF}]
Specifies the number of measurements (samples) the instrument takes per trigger.

Return ten sets of four resistance measurements, using an external trigger to
start each measurement set:

The front panel sample annunciator ( " * " ) turns on during each measurement at slower rates. The
l
annunciator toggles at a fixed rate for fast measurements.
You can use the specified sample count in conjunction with a trigger count (TRIGger:COUNt), which
l
sets the number of triggers to be accepted before returning to the "idle" trigger state. The total num-
ber of measurements returned are the product of the sample count and trigger count.
You can store up to 1,000 measurements in the reading memory of the 34460A, 10,000 meas-
l
urements on the 34461A, 50,000 measurements on the 34465A/70A ( without the MEM option), or
2,000,000 measurements on the 34465A/70A ( with the MEM option). If reading memory overflows,
new measurements overwrite the oldest measurements stored; the most recent measurements are
always preserved. No error is generated, but the Reading Mem Ovfl bit (bit 14) is set in the Ques-
tionable Data Register's condition register (see
