4. Data stored in memory overwrites the data from a previous command.
5. Each reading stored in memory is four bytes (REAL 32-bit). This
format cannot be changed.
6. Each multimeter instrument within the HP 75000 Series B or Series C
mainframe is allocated enough memory to store a minimum of
100 readings.
If greater than 100 readings are requested, the mainframe multiplies
the
TRIGger:COUNt setting by the SAMPle:COUNt setting to
determine the exact number. If enough memory is available, an
additional amount is allocated to the multimeter and the readings are
stored. If enough memory is not available, an error message occurs
and the command is aborted.
The number of additional readings which can be stored in memory
depends on the amount of memory in your system and on the number
of instruments which use the memory.
7. The memory allocated to the multimeter above the amount required
to store 100 readings remains dedicated to that multimeter until
*RST
is executed or until power is cycled. Once de-allocated, the memory
is available to any instrument.
Example: Storing
Readings in Mainframe
Memory
To store measurements in mainframe memory, execute:
INIT[:IMMediate]
following the CONFigure command (or any applicable low-level commands).
10 !Configure the multimeter.
20 OUTPUT 70903;"CONF:FRES 1861,MAX,(@100:103)"
30 OUTPUT 70903;" RES:OCOM ON"
40 OUTPUT 70903;" TRIG:COUN 3"
50 !
Place the multimeter in the wait-for-trigger state, store the readings
60 !in memory.
70 OUTPUT 70903;"INIT"
Retrieving Data From
Mainframe Memory
Data stored in mainframe memory is retrieved using:
FETCh?
Once the data is fetched, it is available to the computer via the output
buffer. Refer to the next example.
