Command
:SOURce:CHANnel[m]:FREQuency
Syntax
:SOURce:CHANnel[m]:FREQuency<wsp><value>
Description
Set the laser frequency
Parameters
<value> is a valid numerical value which is in the range between the MIN and MAX response
queried with the FREQuency? command seen below, or found in the FLS-2800 specifications
Response
None
Example
SOUR:CHAN1:FREQ 1.92e+14
Command
:SOURce:CHANnel[m]:FREQuency?
Syntax
:SOURce:CHANnel[m]:FREQuency?<wsp>[MIN|MAX|SET|LOCK|ALL]
Description
Get the laser frequency
Parameters
MIN: Get the minimum programmable value
MAX: Get the maximum programmable value
SET: Get the desired set value (default)
LOCK: Query whether the laser is currently at the SET frequency
ALL: Returns all of the above parameters
Response
Returns the minimum, maximum or currently set frequency for the laser as specified by
parameters. The lock parameter will return as
true
or
false
Example
SOUR:CHAN1:FREQ? MAX -> 1.9214
Command
:SOURce:CHANnel[m]:FREQuency:FINE
Syntax
:SOURce:CHANnel[m]:FREQuency:FINE<wsp><value>
Description
Set or the laser frequency fine tuning
Parameters
<value>: A valid numerical value in the frequency fine tuning range. Fine tuning can increase
or decrease the frequency (positive or negative value). Valid range is from -6 GHz to 6 GHz in
1 MHz increments as detailed in the specifications.
Response
None
Example
SOUR:CHAN1:FREQ:FINE 2e+06
Command
:SOURce:CHANnel[m]:FREQuency:FINE?
Syntax
:SOURce:CHANnel[m]:FREQuency:FINE?<wsp>[MIN|MAX|ACT|ALL]
Description
Get the laser frequency fine tuning
Parameters
MIN: Get the minimum programmable value
MAX: Get the maximum programmable value
ACT: Get the current value (default)
ALL: Returns all of the above parameters
Response
Returns the minimum, maximum or currently set fine tuning frequency for the laser as
specified by parameters.
Example
SOUR:CHAN1:FREQ:FINE? -> 2.0006
