:
CALCulate:DATA:CWAVelengths?
Function Queries the wavelength value of the OSNR(WDM),
WDM, EDFA-NF, WDM FIL-PK, or WDM FIL-BTM
analysis results.
Syntax
:CALCulate:DATA:CWAVelengths?
Example
:CALCULATE:DATA:CWAVELENGTHS? ->
+1.55000000E-006,+1.56000000E-006
Explanation • If the analysis function has not been executed, a
query error occurs.
• “0” is returned if there is no relevant return value.
• The number of channels to be
output can be acquired by the
:
CALCulate:DATA:NCHannels?
command.
• The value to be output depends on the analysis
performed.
OSNR(WDM) : WAVELENGTH or MEAS WL
WDM : WAVELENGTH or MEAS WL
EDFA-NF: WAVELENGTH
WDM FIL-PK: NOMINAL WAVELENGTH
WDM FIL-BTM: NOMINAL WAVELENGTH
• Data is output in either ASCII or binary form,
depending on the setting of
:FORMat[:DATA]
.
• This is a sequential command.
:CALCulate:DATA:DFBLd?
Function Queries the DFB-LD analysis results.
Syntax
:CALCulate:DATA:DFBLd?
Example
:CALCULATE:DATA:DFBLD? ->
Explanation • If the :CALCulate[:IMMediate] command has not
been executed, a query error occurs.
• “0” is returned if there is no relevant return value
(for example, if the analysis that was executed
was not a DFB-LD analysis).
• This command returns analysis results that
are not returned from the “:CALCulate:DATA?”
command, such as the OSNR value. The
following items are returned. The items are listed
here as abbreviations. For the meaning of these
abbreviations, see section 7.7.
<peak wl>,<peak lvl>,<center wl>,<spec
wd>,<smsr(L)>,<smsr(R)>,<mode
ofst(L)>,<mode ofst(R)>,<snr>,<power>,<rms>,<
Krms>
• This is a sequential command.
• This command can be used on the AQ6370C/
AQ6370D/AQ6373B/AQ6375B.
:CALCulate:DATA:NCHannels?
Function Queries the number of channels of the
OSNR(WDM), WDM, EDFA-NF, WDM FIL-PK, or
WDM FIL-BTM analysis results.
Syntax
:CALCulate:DATA:NCHannels?
Example
:CALCULATE:DATA:NCHANNELS? -> 16
Explanation • If the analysis function has not been executed, a
query error occurs.
• “0” is returned if there is no relevant return value.
• The value is output as ASCII data, regardless of
the setting of
FORMat[:DATA]
.
• This is a sequential command.
:CALCulate:DATA:OSLope?
Function Queries the OUTPUT SLOPE value of the
OSNR (WDM) and WDM analysis results.
Syntax
:CALCulate:DATA:OSLope?
Response <NRf> = Output slope value [dB/nm]
or [dB/THz]
Example
:CALCULATE:DATA:OSLOPE? ->
+2.45352623E-001
Explanation • A query error will occur if the analysis function
is not implemented.
• “0” is returned if there is no relevant return
value (for example, if the analysis that was
executed was not a WDM analysis).
• Analysis results can be queried even if the
output of the OUTPUT SLOPE value is set to
OFF.
• ASCII data is returned regardless of the
setting specified by the :FORMat:[DATA]
command.
• This is a sequential command.
•
This command can be used on the AQ6370C/
AQ6370D/AQ6373B/AQ6375B.
:CALCulate:DISPlay
Function Sets/queries the display format of analysis
results.
Syntax
:CALCulate:DISPlay<wsp>0|1|2|3|4
:CALCulate:DISPlay?
0: TRACE&TABLE
1: TABLE
2: TRACE
3: GRAPH&TABLE
4: GRAPH
Example
:CALCULATE:DISPLAY 1
:CALCULATE:DISPLAY? -> 1
Explanation
•
This is a sequential command.
•
This command can be used on the AQ6370C/
AQ6370D/AQ6373B/AQ6375B.
:CALCulate:DISPlay:GRAPh:LMARKer:Y
Function Sets/queries the position of line marker Y1 or
Y2 on the graph display of analysis results.
Syntax
:CALCulate:DISPlay:GRAPh:LMARker:Y<
wsp>1|2,<NRf>[DB]
:CALCulate:DISPlay:GRAPh:LMARker:Y?
<wsp>1|2
1: Line marker Y1. 2: Line marker Y2.
<NRf>: Line marker position
Example
:CALCULATE:DISPLAY:GRAPH:LMARKER:
Y 1,3.4
:CALCULATE:DISPLAY:GRAPH:LMARKER:Y?
1 -> +3.40000000E+000
Explanation
•
This command is valid when the EDFA-NF
analysis results are being displayed on a graph.
•
This is a sequential command.
•
This command can be used on the AQ6370C/
AQ6370D.
