command:
[:SOURce[n]][:CHANnel[m]]:FREQuency:AUTO?
syntax:
[:SOURce[n]][:CHANnel[m]]:FREQuency:AUTO?
description:
Returns the current operation mode.
parameters:
Any value in the specified range (see appropriate User's Guide)
Also allowed:
MIN - minimum programmable value
MAX - maximum programmable value
DEF - default value
response:
0: "Grid Mode" (= Auto Mode off)
1: "Auto Mode"
example:
sour1:freq:auto? 0
affects:
81950A
Notes
This query is equivalent to [:SOURce[n][:CHANnel[m]]:WAVelength:AUTO?
command:
[:SOURce[n]][:CHANnel[m]]:MODout
syntax:
[:SOURce[n]][:CHANnel[m]]:MODout<wsp>FRQ|FRQRDY|0|1
description:
Sets the modulation output mode of the BNC connector on the front panel of tunable laser modules.
parameters:
FRQ or 0:
FRQRDY or 1:
modulation signal is output all the time
modulation is combined with the laser-ready signal.
In this case, the output is kept low when no optical signal is output (for example, while
the laser
is settling after a change of wavelength).
response:
none
example:
sour0:mod 0
affects:
Tunable laser sources with BNC output connector, except 81602A, 81606A, 81607A, 81608A and 81609A.
