Requests the value in the service request enable register.
Response is the sum of the enabled bits.
See Chapter Three for more information about register structure.
*SRE?-Response 136 means the service request enable register condition summary and error
message bits are enabled (8 + 128 = 136).
The STATMENU:LINEn: command path is used to access the selected channel's status menu
display selection commands. (n can be either 1 or 2). Line 1 only displays measurement from laser
source 1 and line 2 displays measurements from laser source 2. The letter n is either 1 or 2, to
indicate lines on the Status menu.
The following commands may be reached directly from the STATMENU:LINEn: command path.
STATMENU:LINEn:IPD
STATMENU:LINEn:LDI
STATMENU:LINEn:PPD
STATMENU:LINEn:VF
The STATMENU:LINEn? query returns name of the measurement that is currently being displayed
on line n of the status menu. (n can be either 1 or 2).
None. The response is character data which represents the measurement that is currently being
displayed on line 1 of the selected channel's portion of the status menu.
The possible responses are 1. "LDI" laser diode current.
2. "IPD" photodiode current.
3. "PPD" optical power.
4. "VF" laser diode forward voltage.
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.
The letter n is either 1 or 2, to indicate lines on the Status menu.
STATMENU:LINE1?-response: "PPD", means that optical power from laser 1 is selected to be
displayed on line 1.
STATMENU:LINE2?-response: "PPD", means that optical power from laser 2 is selected to be
displayed on line 2.
The STATMENU:LINEn:IPD command sets the measurement that is to be displayed on line n of the
status menu to photodiode current ( IPD ).
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:IPD-response: photodiode current of laser 1 is displayed on line 1 of the
STATMENU:LINE2:IPD-response: photodiode current of laser 2 is displayed on line 2 of the sta-tus
menu.
