[:SOURce]:REFerence
Command long form
This command node is only valid
when the SINE instrument is
selected.
[:SOUR]:REF[:STATe][?] <bool> OFF
This selects the Reference output
mode. The values of the
references will available at the
output in place of the existing
frequency and/or power
:[:SOUR]:REF:FREQuency? 1.0 MHz
Query only that will return the
value of the frequency reference.
:[:SOUR]:REF:POWer?
-10.0
dBm
Query only that will return the
value of the power reference.
[:SOUR]:REF:TRACk[?]
<name>
{FREQuency |
POWer | NONE}
NONE
This selects whether the reference
signal parameters track the
frequency or power on the main
sine instrument
[:SOUR]:REF:COPY
This copies the current values from
the main sine parameter to the
reference values.
There is no query form
[:SOUR]:REF:CONFirm[?]
<name>
{DISable |
ALWays |
ABSolute |
INCrease}
DISable
This command is used to
determine if an additional OUTP
ON command is needed before the
reference values are transferred to
the output terminal. This is to
ensure that the reference
parameters, which may be very
different to the main sine
instrument parameters is not
mistakenly output, potentially
damaging the unit under test.
[:SOUR]:REF:CONFirm:
ABSolute[?]
NRf -10 dBm
Sets the threashold at which the
additional OUTP:ON is needed
when switching to the reference
output.
[:SOUR]:REF:CONFirm:INC
rease[?]
NRf -10 dBm
Sets the increase of signal at
which the additional OUTP:ON is
needed when switching to the
reference output.
[1] These command nodes are only valid when the SINE instrument is selected.
