B.145 TRIGger:SOURce COMMAND
Syntax:
Short Form: TRIG:SOUR {BUS | EXT | IMM}
Long Form: TRIGger:SOURce {BUS | EXT | IMM}
Description: Selects the active trigger source. When TRIG:SOUR BUS is set, an event trigger is created by
sending either *TRG or GPIB <GET> commands. When TRIG:SOUR EXT is set, the trigger is created
by connecting the external trigger line (J2, pin 4 or pin 3 of the mating connector for J2) to analog sig-
nal ground (J2, pin 1 or J2 mating connector, pin 1). The trigger must be armed by sending either
INIT:IMM or INIT:CONT enable (ON) commands prior to sending the selected trigger command. (see
PAR. A.16). Receipt of the active trigger causes the power supply to program to the previously stored
values of VOLT:TRIG and CURR:TRIG (actual output voltage/current is dependent upon the load).
Sending TRIG:SOUR IMM causes the next VOLT:TRIG or CURR:TRIG to immediately program the
output, regardless of trigger arming. *RST sets TRIG:SOUR to IMMediate. Related Commands:
<GET>, *TRG, INIT:IMM, INIT:CONT.
B.146 TRIGger:SOURce? QUERY
Syntax:
Short Form: TRIG:SOUR?
Returns: BUS, IMMEDIATE or EXTERNAL
Description: Identifies whether internal, immediate or external trigger is activated.

The Device error bit may be set when the status monitoring functions of the power supply detect an overvoltage/under-
voltage condition.

Device Error bit 3
Indicates the power supply or one of the connected power
supplies has detected an error. These errors are an indica-
tion of a hardware problem in either the BOP or the BOP
system consisting of a master and up to four slave BOPs to
create additional current or voltage. The last two digits of the
error code indicate the type of error and its source; xx indi-
cates the position of the unit on the BITBUS:
xx = 1: Device 1 (Master)
xx = 2: Device 1 (Slave 1)
xx = 3: Device 1 (Slave 2)
xx = 4: Device 1 (Slave 3)
xx = 5: Device 1 (Slave 4)
(1)
Device Error bit 3
Indicates a hardware problem has been detected in either
the BOP power supply or an auxiliary power supply, such as
Kepco's MST, MAT, MBT or low power (under 1KW) BOP,
connected to the BITBUS. The last two digits of the error
code indicate the type of error detected,; yy indicates the
position of the unit on the BITBUS
yy = 2: Device 2 through yy = 15: Device 15
