CALCulate:DBM:REFerence {< value
>|MINimum|MAXimum}
Select the dBm reference value. Choose from: 50, 75, 93, 110, 124, 125, 135,
150, 250, 300, 500, 600 , 800, 900, 1000, 1200, or 8000 ohms.
MIN
= 50
Ω
.
MAX
= 8000
Ω
. [Stored in non-volatile memory]
CALCulate:DBM:REFerence? [MINimum|MAXimum]
Query the dBm reference resistance.
CALCulate:LIMit:LOWer {<
value
>|MINimum|MAXimum}
Set the lower limit for limit testing. You can set the value to any number
between 0 and
±
120% of the highest range, for the present function.
MIN
= –120% of the highest range.
MAX
= 120% of the highest range.
[Stored in volatile memory]
CALCulate:LIMit:LOWer? [MINimum|MAXimum]
Query the lower limit.
CALCulate:LIMit:UPPer {< value
>|MINimum|MAXimum}
Set the lower limit for limit testing. You can set the value to any number
between 0 and
±
120% of the highest range, for the present function.
MIN
= –120% of the highest range.
MAX
= 120% of the highest range.
[Stored in volatile memory]
CALCulate:LIMit:UPPer? [MINimum|MAXimum]
Query the upper limit.
DATA:FEED RDG_STORE, {"CALCulate"|""}
Selects whether readings taken using the
INITiate
command are
stored in the multimeter’s internal memory (default) or not stored at all.
In the default state (
DATA:FEED RDG_STORE, "CALC"
), up to
512 readings are stored in memory when
INITiate
is executed.
The
MEASure?
and
CONFigure
commands automatically select
"CALC"
.
With memory disabled (
DATA:FEED RDG_STORE, ""
), readings taken
using
INITiate
are not stored. This may be useful with the min-max
operation since it allows you to determine an average of the readings
without storing the individual values. An error will be generated if you
attempt to transfer readings to the output buffer using the
FETCh?
command.
DATA:FEED?
Query the reading memory state. Returns
"CALC"
or
""
.
