The STATMENU:LINEn:LDI command sets the measurement that is to be displayed on line n of the
status menu to laser diode current ( LDI ).
None. The letter n is either 1 or 2, to indicate lines on the Status menu.
The default condition of the status menu displays laser diode current 1 ( LDI ) on line 1 and laser
diode current 2 ( LDI ) on line 2.
STATMENU:LINE1:LDI-response: laser diode current of laser 1 is displayed on line 1 of the status
menu.
STATMENU:LINE2:LDI-response: laser diode current of laser 2 is displayed on line 2 of the status
menu.
The STATMENU:LINEn:PPD command sets the measurement that is to be displayed on line n of
the status menu to optical power ( PPD ).
None. The letter n is either 1 or 2, to indicate lines on the Status menu.
Photodetector power is calculated via the CALPD conversion factor. The measurement is only as
accurate as the user's CALPD value.
STATMENU:LINE1:PPD-response: optical power is displayed on line 1 of the status menu.
STATMENU:LINE2:PPD-response: optical power is displayed on line 2 of the status menu.
The STATMENU:LINEn:VF command sets the measurement that is to be displayed on line n of the
status menu to laser diode forward voltage ( VF ).
None. The letter n is either 1 or 2, to indicate lines on the Status menu.
STATMENU:LINE1:VF-response: laser diode forward voltage of laser 1 is displayed on line 1 of the
status menu.
STATMENU:LINE2:VF-response: laser diode forward voltage of laser 2 is displayed on line 2 of the
status menu.
Requests the value in the status byte register.
Response is the sum of the enabled bits.
See Chapter Three for more information about register structure.
*STB?-Response 200 means the status byte condition and master status summary bits, and error
message bits, are enabled. (8 + 64 + 128 = 200)
